TWiM investigates the high variability in the rate and amount of current production from microbial fuel cells, and how bacteria link their growth rate to external nutrient conditions via a protein that functions as a cellular rheostat.
TWiM reveals environmental integrons, bacterial genetic elements notorious for their role in spreading antibiotic resistance, and how Salmonella invasion is controlled by competition among intestinal chemical signals.
On this episode of TWiM, using colicins to ferry DNA into cells through an iron transporter, and construction of highly efficient microbial fuel cells that produce more electrical current than previously observed.
