The mutants of Shewanella oneidensis MR 1 resistant to fosfomycin, a toxic analogue of phospho enolpyruvate, were obtained. The mutants exhibited increased reducing activity and higher rates of lactate utilization. A correlation was shown between the rates of metabolism of oxidized substrates and the rate of reduction of methylene blue, a mediator of electron transport. The mutants of S. oneidensis MR 1 may be used in microbial fuel cells for intensification of energy production from organic compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
