Podcasts about microbial

This episode was recorded at the 2025 Florida Ruminant Nutrition Symposium. Microbial protein has always been Dr. Frikins' main interest. It's the most important and consistent source of protein for the cow, with a very high amino acid content. Histidine is the only exception, but bypass protein sources high in histidine complement microbial protein well. Our assessment of microbial protein is all based on prediction models. In his presentation, Dr. Firkins talked about what we can do to have consistently high microbial protein production and how to make the best use of the models. He touched on starch and fat content as two areas of focus, emphasizing a balanced diet to achieve a balanced supply of microbial protein. (5:36)Dr. Firkins notes that about 90% of the bacteria in the rumen can't be cultured, and there is great diversity in the rumen. There's a core group of bacteria that almost every cow has that are really good at their job because they've been co-selected along with the cow for fiber digestion. The panel discusses how much the microbiome changes over time, host interactions with the microbial population, and inoculation of calves at birth and weaning. (8:47)Dr. De Souza and Dr. Faciola talk about starch associative effects and their impacts on fiber digestibility, how sugars impact the rumen and butyrate production, and the importance of butyrate in de novo milk fat synthesis. Dr. Frikins hypothesizes that when sugars improve fiber digestibility, the sugar stimulates how fiber digesters do their job. Some studies have shown an increase in rumen pH when sugars are supplemented, which may be part of the mechanism of improved fiber digestibility. However, he doesn't recommend using sugars when there is a lot of starch in the diet. (13:38)Dr. Faciola and Dr. Firkins discuss some of the finer points of the dietary starch and fiber digestibility relationship. What are you replacing when you add more starch? What is the proper amount of effective fiber in higher-starch diets? On the other hand, if you decrease starch a little bit, there might be more room for fat. Well-managed cows with adequate effective fiber can probably handle more starch. Dr. Firkins underlines that starch is more digestible than fiber and thus supports microbial protein, but an optimum level is desirable, perhaps 28-20%. (20:37)The panel talks about microbial growth efficiency and the energy-spilling mechanisms some bacteria have. Some models suggest that starch-digesting bacteria have higher maintenance energy requirements. The group then pivots to methane production and available feed additives marketed to reduce methane. Dr. Firkins notes that there is quite a bit of variability in the additives. He emphasizes that if we're using these products, we need to know and measure what's in them and have them be consistent. This is challenging due not only to variability in product, but also rumen adaptation. Dr. Firkins also reminds the audience that improving the cow's efficiency in general in a variety of ways will lead to a smaller environmental footprint. This can range from improving reproductive efficiency to understanding differences in the microbiome of cows who emit more or less methane and trying to shift microbial populations to those with lower emissions. (23:12)Dr. De Souza and Dr. Firkins discuss fatty acid supplementation and fiber digestion relationships. Dr. Firkins explains that in the microbiology literature, it's common to culture bacteria in a simple or complex medium, then add yeast culture. Interestingly, the yeast culture contains a lot of palmitic acid, which has been shown to improve fiber digestibility. He suggests the cell membrane of the bacteria is very critical. When fat supplementation depresses fiber digestibility, he suspects it's disrupting the bacterial membrane. Dr. De Souza recommends 1-2% palmitic acid in the diet for optimal results. (33:58)The panel touches on the importance and relevance of in vitro fermentation work, why histidine is the limiting amino acid in microbial protein, and Dr. Firkins' passion for protozoa. (43:08)Panelists share their take-home thoughts.

This episode was recorded in Reno, Nevada, during the 2025 Western Dairy Management Conference. The panel discusses their individual experiences with outbreaks in different states. Beth talks about her group's microbial surveillance technology they used to compare rectal swabs from positive and non-positive herds. They noted elevations in specific virulent E. coli, Salmonella spp., and Clostridium perfringens in the HPAI-positive herds. Enrique noted that in California, the outbreak began in the South Valley during periods of heat stress, which exacerbated symptoms. He also felt that some dairies panicked a little and moved cows too much, which did not help. In the North Valley, the outbreak happened in cooler weather, and dairies purposefully did not move cows out of their pens and provided supportive therapy within the pen. (5:25)Dr. Schcolnik emphasized making sure i's are dotted and t's are crossed in your nutrition program to help manage through an outbreak. The immune system is an obligate glucose utilizer, so energy is key, as are protein and trace minerals. He noted they also added binders to diets, and either probiotics or double doses of yeast to keep the rumen healthy. Decreasing intake is a big symptom, so he recommends vitamin B supplementation to stimulate appetite. (12:30)The panel discusses how the Texas and California outbreaks differed from one another, including heat stress, recovery in milk production after infection, bird migration and cattle movement. Enrique notes that in California, it seemed like transmission was going downwind. Animal movement, wild birds and milk trucks were also implicated. (14:31)Several companies are investing in vaccine development, but the virus mutation is a challenge. Dr. Spencer wonders if the vaccine will end up resembling the human flu vaccine where you hope to target the general structure of the virus to reduce impact. The panel talks about natural immunity and how cows will be impacted in the lactation after they were ill. Dr. Schcolnik has observed that a percentage of cows who were dry during the outbreak aren't performing as well after freshening. He hypothesizes this could be due to mammary cell death during infection, as the virus lyses the cell as it exits the cell. (24:41)The panel discusses practical recommendations for dairy producers to prepare for or help mitigate during an outbreak. Biosecurity is key. Vaccines are hopefully on the way, but until then, minimizing cattle movements within the herd, post-dipping cows as soon as possible after the machine falls off and minimizing splashing of milk are all good practices. The panel looks forward to more research about all the different ways the virus transmits. They're also eager to learn more about treatment plans and what has worked for different dairies regarding giving fluids, altering rations, boosting the immune system, managing co-infections and impacts on calves and heifers. (29:18)Lastly, panelists share their take-home thoughts. (37:33)Scott invites the audience to Bourbon and Brainiacs at ADSA in Louisville - a bourbon tasting with all your favorite professors!

In this episode, we detail the oral microbiome and its relationship with the intestinal microbiome, detailing the oral-gut microbiota axis. We discuss the stepwise development of oral biofilm, the transition from plaque to dental calculus, and potential systemic impacts of oral dysbiosis, while highlighting intestinal health and focusing on Fusobacterium nucleatum. We then detail possible symptoms of oral dysbiosis as well as testing modalities. Topics:1. Overview of the Oral Microbiome and the Oral-Gut Axis - The oral cavity and the gut: microbially dense sites. - These regions are anatomically distinct but connected and capable of influencing each other. - The oral microbiome: bacterial species, fungi, viruses, archaea, protozoa. - Microbial distribution is influenced by the topography and chemistry of various oral surfaces. 2. Oral Cavity Anatomy and Microenvironments - The oral cavity is divided into the vestibule and oral cavity proper. - Lined by oral mucosa, which varies in structure. - These anatomical variations create unique ecological niches that support different microbial populations. 3. Tooth Structure and Relevance to Microbial Colonization - Teeth are embedded in the alveolar processes of the maxilla and mandible. - Tooth structure. - Long-term microbial colonization and biofilm development. 4. Biofilm / Dental Plaque Development - Biofilm begins with the formation of the acquired pellicle.- Pioneer species secreting extracellular polymeric substances (EPS).- Secondary colonizers coaggregate.- Coaggregation is species-specific.- Example.- Aerobes can lower local oxygen levels, creating micro anaerobic niches that support obligate anaerobes. 5. Maturation of the Biofilm  - Biofilm composition shifting to anaerobic, proteolytic species such as P. gingivalis. - F. nucleatum: a bridge species. 6. Mineralization and Formation of Dental Calculus - Mineralization, calcium and phosphate deposition. - Dental calculus. - Can promote further accumulation and worsen inflammation. 7. Oral Dysbiosis  - An imbalance in the oral microbial community. - Potential signs and symptoms. - Halitosis, swollen or bleeding gums, tooth sensitivity, new cavities, dry mouth or altered taste, recurrent infections, coated tongue, plaque buildup near the gumline. 8. Oral-Gut Axis and Systemic Implications - Physical, chemical, biochemical, and immunological barriers aid in preventing oral bacteria from colonizing the gut. - Oral bacteria can potentially impact intestinal health. -  F. nucleatum and IBD. 9.

This Podcast Extra episode is from John's Ask Me Anything webinar from April 14. Drawing from his extensive research and firsthand experience, John will provide insights and practical solutions to help growers achieve healthier, more resilient crops. In this discussion, the topics cover: Nutritional management with copper, nitrogen, potassium, and calcium prevents wheat and barley lodging better than PGRs.  Soil aeration and oxygen flow enhance paramagnetism more effectively than paramagnetic rock powders. Side-dressing potassium, like potassium nitrate, benefits soil biology more than broadcasting potash. Adequate calcium and boron levels, plus soil aeration, reduce clubroot in brassicas. Compost, low soil carbon, and lack of humic substances cause high chloride in plant sap, mitigated by humicarb. Selenium may influence fatty acid profiles and yield in forages, but its role in oil crops is unclear. Balancing potassium and calcium with manganese and boron ensures optimal plant health. Microbial activity and preventing soil drying enhance potassium availability in clay soils. Micropack offers higher performance than seaweed or fish-based foliar sprays for tropical fruit groves. Deeper earthworm presence reflects better soil aeration and structure, not necessarily overall soil health. Seed Flare may penetrate sunflower shells but is less effective on stone fruit, needing experimentation. BioCoat Gold is best as a seed treatment but can be applied in-furrow.  About John Kempf John Kempf is the founder of Advancing Eco Agriculture (AEA). A top expert in biological and regenerative farming, John founded AEA in 2006 to help fellow farmers by providing the education, tools, and strategies that will have a global effect on the food supply and those who grow it.

Dr. Amato is a biological anthropologist studying the influence of gut microbes on host ecology and evolution. Her research examines how changes in the gut microbiota impact host nutrition, energetics, and health. She uses non-human primates as models for studying host-gut microbe interactions in selective environments and for providing comparative insight into the evolution of the human gut microbiota. Her main foci are understanding how the gut microbiome may buffer hosts during periods of nutritional stress and how the gut microbiome programs normal inter-specific differences in host metabolism. In this realm, she is also interested in global variation in the human gut microbiome and its implications for local human adaptation. Dr. Amato obtained her A.B. in Biology from Dartmouth College and her Ph.D. in Ecology, Evolution and Conservation Biology from the University of Illinois at Urbana-Champaign. She completed a postdoc at the University of Colorado Boulder. She joined the Department of Anthropology in 2015. She is also affiliated with the Interdisciplinary Biological Sciences Graduate Program and sits on the Executive Committee of the Northwestern Institute on Complex Systems.

A road trip to a gypsum quarry in Algeria led Youcef Sellam on a journey of scientific discovery. From the road trip to an internship in Italy, he and his colleagues later discovered microbial fossils—marking a first for Algerian gypsum. As a Ph.D. student at the University of Bern, Sellam and his team took this research further. They used a special instrument to detect the chemical signatures of these ancient microbes, demonstrating a method that could one day help search for traces of life on Mars. Their findings, published in Frontiers in Astronomy and Space Sciences, highlight how chemical analysis can reveal biological traces in minerals. Join planetary scientist Beth Johnson and Youcef for a discussion of how this research brings us one step closer to understanding how we might detect past life on the Red Planet.

In this podcast, Dr. Anne Madden, founder of the Microbe Institute, shares why understanding microbes is important and why she is compelled to educate others.

Most dairy farms are trying to push the envelope from the conventional 4L of milk replacer per day to a higher volume to support lean structural growth of replacement heifers. Concerns of ruminal leakage resulting in fermentation has been cited as a concern, but is that based on an incomplete picture?  We know microbial protein offers a nearly perfect alignment of amino acid requirements for the bovine, however nutrition programs have discounted milk replacer to exclusively providing rumen undegradable protein (RUP) – protein that skips the rumen and is absorbed in the abomasum. Marcos Marcondes, researcher from the Miner Institute, wanted to see if feeding higher volumes would change the flow of protein and energy to the calf and the physiology of the rumen, due to leakage. To test this question he fed a standard rate and double rate of milk replacer with colbalt to mark and track the flow of digestion through preweaned animals. Leakage was found in the rumen on both treatments, but the results were positive. Energy, in the form of volatile fatty acids, and microbial protein added to the fuel for these growing animals.  Listen in to better understand the kinetics of digestion and questions that still remain for this phase of production.

In this episode, we detail the cellular make-up of the gastric lining, highlighting hydrochloric acid (HCl) secretion and its role in digestion, micronutrient absorption, and microbial defense. We discuss potential pathophysiological consequences of hypochlorhydria, including impaired digestive signaling, bacterial overgrowth in the small intestine (SIBO), and more. Lastly, we detail upstream microbial control, focusing on the influence of the oral microbiome and oral dysbiosis.Topics: 1. Introduction- Highlighting the stomach and hypochlorhydria / low stomach acid, as well as microbial balance, dysbiosis, and overgrowth.- Discussion of intestinal microbiome and oral microbiome. 2. Gastric Anatomy and Mucosal Layers- The stomach: cardia, fundus, body, pylorus.- The gastric mucosa: epithelial lining, lamina propria, muscularis mucosae.- The epithelial layer: mucous cells, parietal cells, chief cells, enteroendocrine cells.- Beneath the mucosa: submucosa and muscular layers that contribute to gastric motility, mechanical digestion, and more. 3. Mucous Cells - The surface epithelium and gastric pits.- Secretion of thick, viscous mucus.- Protecting the epithelium.- The mucus traps bicarbonate ions: neutral microenvironment that protects against acid-induced damage. 4. Parietal Cells and Gastric Acid Secretion- Secretion of hydrochloric acid (HCl): denatures dietary proteins, sterilizes ingested food.- Parietal cells produce intrinsic factor: binds vitamin B12 to facilitate absorption in the ileum. 5. Chief Cells and Pepsinogen- Secretion of pepsinogen: activated by low pH into the proteolytic enzyme pepsin.- Pepsin and protein digestion.- Release of gastric lipase. 6. Hydrochloric Acid: Digestive and Protective Roles- Immune defense.- Pepsinogen activation.- Adequate gastric acidity essential for properly acidified chyme.- Priming release of bile and pancreatic enzymes. 7. The Small Intestine, Stomach, and Microbial Regulation- The pyloric sphincter.- The stomach supports minimal microbial diversity.- Acidic barrier aids in limiting the entry of opportunistic microbes into the small intestine. 8. Hypochlorhydria, Low Stomach Acid- Hypochlorhydria can compromise one of the body's defense mechanisms.- Colonization of the small intestine.- Insufficient pepsinogen activation and possible protein digestion impairment.- Suboptimal chyme formation and downstream digestive capacity.- Possible symptoms of hypochlorhydria.- Possible impaired absorption of micronutrients including vitamin B12, iron, calcium, magnesium.- H. pylori infection, autoimmunity, aging. 9. The Oral Microbiome, Intestinal Microbiome, and Dysbiosis- Oral and environmental microbes.- Altered gastric pH, bile, digestive enzymes, and more.- The oral cavity as the gateway to the GI tract.- Oral microbial species.- Oral hygiene and oral microbiome health. 10.

SpaceTime Series 28 Episode 29The Astronomy, Space and Science News PodcastExploring Callisto's Ocean Potential, Laser Fossil Detection on Mars, and ISS Cleanliness ConcernsIn this episode of SpaceTime, we dive into exciting new research suggesting that Jupiter's moon Callisto may harbor a subsurface ocean, potentially making it another ocean world in our solar system. This revelation builds on data from NASA's Galileo spacecraft, which hinted at the presence of a salty liquid water ocean beneath Callisto's icy crust. Advanced modeling techniques have strengthened these claims, setting the stage for further exploration by NASA's Europa Clipper and ESA's Juice missions.Lasers on Mars: Searching for Ancient LifeWe also discuss innovative research that proposes using lasers to identify ancient microbial fossils on Mars. Scientists have successfully detected microbial fossils in gypsum on Earth, raising hopes that similar techniques could uncover evidence of past life on the Red Planet. The findings suggest that gypsum deposits on Mars could conceal traces of ancient life, preserved in mineral formations that formed when water evaporated billions of years ago.Health Implications of Sterility on the ISSAdditionally, we explore a new study indicating that the overly sterile environment of the International Space Station may be negatively impacting astronaut health. The research suggests that introducing a diverse range of microbes could potentially alleviate immune dysfunction and other health issues experienced by crew members during long missions in space.00:00 Space Time Series 28 Episode 29 for broadcast on 7 March 202500:49 New findings on Callisto's potential subsurface ocean06:30 Implications for future missions to Jupiter's moons12:15 Using lasers to detect ancient life on Mars18:00 Analysis of gypsum deposits and their significance22:45 Concerns regarding ISS cleanliness and astronaut health27:00 Overview of March's night sky and celestial events30:15 Celebrating PI Day and its significance in astronomywww.spacetimewithstuartgary.comwww.bitesz.com
