Mutants of Escherichia coli K12 strain WGAS-GF+/LF+ were selected for their inability to use fumarate as terminal electron acceptor for supporting growth on glycerol or lactate in an atmosphere of H2 plus 5% CO2. Eighty-three mutants were grouped into seven different categories according to their ability to grow on different media and their ability to produce gas during glucose fermentation. En...
Fumarate reductase from Escherichia coli functions both as an anaerobic fumarate reductase and as an aerobic succinate dehydrogenase. A site-directed mutation of E. coli fumarate reductase in which FrdB Pro-159 was replaced with a glutamine or histidine residue was constructed and overexpressed in a strain of E. coli lacking a functional copy of the fumarate reductase or succinate dehydrogenase...
Rupatadine fumarate is a potent dual antagonist of histamine and platelet-activating factor antagonist (PAF antagonist) and used to treat allergies. During the process development of rupatadine fumarate, five related substances were observed in Rupatadine fumarate and one new related compound was observed during the stress oxidative degradation study. These related substances were identified as...
BACKGROUND/AIMS Motility is a feature of many pathogens that contributes to the migration and dispersion of the infectious agent. Whether gentamycin has a post-antibiotic effect (PAE) on the swarming and swimming motility of Escherichia coli (E. coli) remains unknown. In this study, we aimed to examine whether short-term pretreatment of sub-inhibitory concentrations of gentamycin alter motility...
Escherichia coli K-12, grown under anaerobic conditions with glucose as the sole source of carbon and energy without any terminal electron acceptor added, contains a fumarate reductase system in which electrons are transferred from formate or reduced nicotinamide adenine dinucleotide via menaquinone and cytochromes to fumarate reductase. This fumarate reductase system plays an important role in...
