oldies but goodies from 𝕏 - now for #MicroSky on 𝕏 by 𝗠𝗮𝗴𝘁𝗲𝗿𝗶𝗮 𝗨𝗣𝗩/𝗘𝗛𝗨 @MagteriaUPV on Sep 10, 2020 Here is our contribution to #InternationalMicroorganismDay A group of the magnetotactic bacteria MSR-1 🦠 filled with nanomagnets (magnetosomes) 🧲 @femsmicro.bsky.social

What are those three white blobs, and why do we spend hours at our microscopes recording movies like this? 🧐 Take a look at this short article on the 'bead assay' - a simple yet powerful technique that helps us, and many others, uncover the secrets of the bacterial flagellar motor!

New preprint! We find the relationship between the flagellar motor (FM) speed and the proton motive force (PMF) to be nonlinear in E. coli, limited by the maximum torque that a motor can supply. Surprisingly, this max. torque is reachable physiologically. (1/9) biorxiv.org/cgi/content/...
