Abstract
The defined medium A of W. R. Sistrom (W. R. Sistrom, J. Gen. Microbio l. 22:77-85, 1960) has been modified to allow the growth of Rhodospiri llum rubrum in large-scale batch cultures under dark, semiaerobic cond itions. The simultaneous use of two substrates, NH4-succinate (46 mM) and fructose (0.3%), which are utilized in aerobic and fermentative me tabolism, respectively, leads to very high cell densities with a maxim al yield of photosynthetic membranes.
