Transcription profiling of G sulfurreducens GGS nitrogen fixation

ABSTRACT: G. sulfurreducens (ATCC #51573) was obtained from the laboratory culture collection of Dr. Derek Lovley. Cells were grown under strict anaerobic conditions at 30 °C in chemostats, as previously described (for more information see Esteve-Núñez, A., M. M. Rothermich, M. Sharma, and D. R. Lovley. 2004. Growth of Geobacter sulfurreducens under nutrient-limiting conditions in continuous culture. Environ. Microbiol.:in press.), with acetate (5 mM) as the electron donor and fumarate (27.5 mM) as the electron acceptor. For growth in the absence of fixed nitrogen, the ammonium chloride (4.7 mM) was omitted from the medium and fumarate served as the electron acceptor. Therefore, cultures with ammonium chloride were limited by acetate while cultures without ammonium chloride were limited by nitrogen.
