Cool story on the importance of feedback loop and a phase transition in co-culture growth on chitin with connected modeling

Uwe now switches to a stable 10-member course gut community (from OMM12 strains) and the influence of different polymers

and back to marine systems and chitin particles (spatial restrictions) through the PNAS paper of @sammy-pontrelli.bsky.social

Sarahi explains their work on microbial diversity in enrichment pure cultures - the value of community-based cultivation to discover different ecological strategies, autotrophy for amino acids and vitamins

See their work in @commsbio.nature.com

Sarahi highlights the biological organization concepts applied for microorganisms from cell, population, and pairwise interactions to consortium, microbial cohort, and finally to community level

James explains that their mother machines, growing the wild type and clock mutant next to each other in the mother machines and they observed a minor difference in growth at the first 12 hour which translates to fitness difference

#MibiNet

James finishes with highlighting the importance of clock on fitness of Synecococcus

Refers to Woelfle et al 2004 and Hellweger 2010 - fitness caused by clock deletion could be measured in competition in flask, but not at single cell level

#MibiNet

James explains their experiments with mother machines (microfluidic devices) to follow gene expression at single cell level for circadian clock expression: removing input had hardly influence, unlike core clock mutants

See their @natcomms.nature.com paper

#MibiNet

James explain how a simple clock can regulate more complex processes in the cells that are not happening every 24 hours

#MibiNet

James introduces circadian clock from humans and animals to plants and focuses on cyanobacterial clock, KaiA, KaiB, and KaiC including the clock in the test tube
