Abstract
Rhodobacter sphaeroides is non-sulfur purple photosynthetic bacteria exhibiting versatile growth capabilities in aerobic or anaerobic culture condition. In this study, seven organic acids were used in order to analyze the effect of cell growth according to various carbon sources. R. sphaeroides were cultured on sistrom’s minimal medium in the presence of acetate, citrate, lactate and 4 carbon-organic acids such as fumarate, malate, succinate and oxaloacetate during 60 hr, respectively. The result showed that growth rate under the culture condition with 4 carbon-organic acids was more increased than those with acetate, citrate and lactate. Moreover the growth rate of R. sphaeroides was drastically enhanced when used succinate as a carbon source. It means that R. sphaeroides is effectively able to use 4 carbon-organic acids as carbon source.
