    SIPs with Standards

    Stable Isotope Probing (SIP) is a powerful technique for studying microbial communities. These experiments can show which microbes are handling specific nutrients, or what they're doing with those nutrients, and even how quickly. But there's a catch: SIP labwork and analysis can be very demanding. The JGI offers SIP analysis to make these experiments accessible to more researchers. Ultimately, the goal is to generate SIP data that can be useful to multiple teams and analyses.This episode, Rex Malmstrom (JGI), and Roli Wilhelm (Purdue University), share a few different ways they're working to make this technique, SIP, more standardized -- more reproducible, more reusable, and more insightful, for the future of studying microbial communities.Links from this episode:Submit your own proposal to work with the JGIFind all episode transcripts on our websiteJGI's Micro-Scale Applications GroupMISIP: a data standard for the reuse and reproducibility of any stable isotope probing-derived nucleic acid sequence and experimentHT-SIP: a semi-automated stable isotope probing pipeline identifies cross-kingdom interactions in the hyphosphere of arbuscular mycorrhizal fungiWebinar: Metagenome quantitative SIP at the JGI: https://www.youtube.com/watch?v=5OgLDTw7eYA Genome Insider: Party in the Rhizosphere Genome Insider: A Powerful Technique to Study Microbes, Now Easier Simulating metagenomic stable isotope probing datasets with MetaSIPSim Microbes Persist: Systems Biology of the Soil Microbiome Science Focus Area (SFA), led by Dr. Jennifer Pett-Ridge at Lawrence Livermore National Laboratory (LLNL)Our contact info:X: @JGIEmail: jgi-comms at lbl dot gov

    Biofuels and bioproducts are a way to kick our addiction to fossil fuels. In this episode, we get a peek into how scientists Aindrila Mukhopadhyay and Steve Singer are harnessing the versatile bacterium Pseudomonas putida to break down biomass and help bring about a more sustainable, bio-based economy. They conduct research at the Joint BioEnergy Institute (JBEI), a JGI partner and one of the four US Department of Energy Bioenergy Research Centers. Find more info on this episode, including the transcript, at https://jgi.doe.gov/genome-insider-s2ep3-better-living-through-bioenergy/

    Diatoms, a group of tiny algae, are also known as “living opals” because of the strange, beautiful properties of their silica shells. But what genes are responsible for such mesmerizing exteriors? Setsuko Wakao and Kris Niyogi, biologists at UC Berkeley and Lawrence Berkeley National Laboratory, aim to find out.

    A tall native plant of the North American prairie, switchgrass (Panicum virgatum) has long been a tantalizing potential biofuel feedstock. But switchgrass has a complex genome and, as a species, encompasses dizzying diversity. So, a team of scientists made an ambitious plan to link the plant’s diverse traits — height, biomass, hardiness to cold, etc. — to its genes. The undertaking took shovels, trucks — and more than a decade. With the results just published in the journal Nature, listen to the episode for a romp through their switchgrass story.

    Life as we know it wouldn’t exist without cyanobacteria; they began oxygenating Earth over two billion years ago. A team of researchers set out to Yellowstone National Park to study how cyanobacteria are living, communally, in microbial mats. Along the way, they’ve encountered surprises, adopted new technologies, and made a few discoveries about the microbial mat denizens.
