Miikka B. Laine et al. demonstrate a refined phospholipid fatty acid (PLFA) analysis protocol that improves lipid separation and quantification in soil samples, revealing that freeze-dried storage at −80 °C preserves microbial community ratios better than −20 °C storage.

How do you exist? I studied plfa and managed to show and complete most of the puzzles, but some eluded me.

I have never met a physics person who also loved dependent types.

I apologize if I am too enthusiastic but I am so glad you exist

man PLFA is so good

Who's hiring functional programmers in 2026?

I've got a recent graduate who has been doing really good work on error messages in dependent types, who's taken both my PLAI and PLFA classes.

Sadly I haven't been at conferences for a while, so I don't know who's giving out shirts these days. Is […]

For this study, we developed a new method, #2H-vapor-PLFA-SIP, which labels soil with 2H-labelled water vapor, allowing to study the activity/growth of microbial communities without altering the soil moisture. Thanks to all involved!

Nutrients, Vol. 17, Pages 821: Organ-Specific Responses to Chronic High-Fat Diets in Mice: Insights into Phospholipid Fatty Acid Distribution
Background/Objectives: This research aimed to investigate phospholipid fatty acid (PLFA) distribution in the brain, kidneys, and white adipose tissue (WAT) and lipid profiles in response to high-fat diets. Methods: Adult female C57BL/6 mice were fed high-fat diets containing 25% linseed, palm, or sunflower oil for 100 days. The fatty acid composition of dietary oils and tissue PL were analyzed using gas–liquid chromatography. Results: Linseed oil increased n-3 polyunsaturated fatty acids (PUFAs) with subsequent conversion into long-chain n-3 PUFAs in the brain and kidney PL, while only alpha-linolenic acid was elevated in WAT. Palm and sunflower oils resulted in unique PLFA distributions in the kidneys and WAT. Palm oil raised linoleic acid without conversion to pro-inflammatory n-6 PUFAs. Sunflower oil increased saturated palmitic acid, as opposed to the rise in monounsaturated oleic acid. Linseed oil also significantly improved lipid profiles, reducing LDL and increasing HDL levels while enhancing cardiovascular indices. Conclusions: This study demonstrates that dietary oils significantly impact organ-specific PLFA profiles, with linseed oil enriching brain and renal n-3 PUFAs, while palm and sunflower oils induce distinct modifications in the kidney and WAT. Moreover, linseed oil offers notable cardioprotective benefits due to the favorable lipid profile changes. These findings highlight the importance of dietary fat selection in achieving balanced lipid metabolism and suggest that diverse oil combinations may be essential for optimizing health outcomes.

Main Responsibilities

• Conduct soil and plant sampling in field experiments
• Analyze microbial communities (amplicon sequencing, PLFA, enzyme assays)
• Investigate microbial traits and C/N cycling under drought
• Collaborate in data analysis and publication writing

If you are interested in the PLFA method and his interpretation, plese have a look at our recent perspective lead by a fantastic researcher, Stefan Gorka, and in collaboration with my dear colleagues @christinakaiser.bsky.social and Hannes Schmidt

This latest paper instead allows us to quantify growth rates via PLFA, both at the community level and group specific. We found that whole community level and bacteria growth rates drop by half, while fungi do not decrease and even increase their growth rates

The study started in 2020 when we put together a great idea with @loutsi.bsky.social @joergschnecker.bsky.social @andreasrichter.bsky.social, to expand the vapor method to qSIP and deuterium in PLFA, sampling an incredible multifactorial experiment called ClimGrass

If you haven’t watched Unification yet it’s the best Trek in ages and will bring a tear to your eye if Kirk/Spock are your thing.

Shatner doing it after Paramount has phased him out was incredible.

We updated existing conversion factors for PLFA and ergosterol biomarkers based on analyses in 30 soil fungal isolates and an updated literature review, and established one for fungal rDNA copy numbers - showing also the pros and cons of such an approach

After 2 months, I‘m back in the lab extracting fatty acids from various deep-sea organisms to assess their potential food sources and to better understand PLFA biosynthesis pathways when combining it with deuterium (stable isotope of hydrogen) enrichments.
