Expression Profile of R. Capsulatus on different nitrogen sources and different concentrations of acetate

ABSTRACT: The influence of different nitrogen sources on transcriptome of Purple non sulfur bacterium R. Capsulatus was investigated by comparing expression profile on 5mM ammonium chloride and 2 mM glutamate. Carbon source was 40mM acetate on both conditions. To study the effect of different acetate concentrations, 40mM and 80mM acetate were used with 2 mM glutamate as nitrogen source. Bacteria were grown anaerobically under continuous illumination (200 W/m2) in 150 ml volume photobioreactors at 30M-BM-0C. For microarray analysis, RNA samples were collected after 16h of inoculation from 1.5x109 cells. A microarray chip for Rhodobacter capsulatus was not commercially available. For that reason, a GeneChipM-BM-. array was custom designed and manufactured by Affymetrix, Santa Clara, California.
