Abstract

The effect of inorganic phosphate concentrations on antibiotic and extracellular protein production by Myxococcus coralloides D have been examined. Antibiotic production by growing cells of this myxobacterium was maximal at phosphate concentrations of 10-20 mM, but was inhibited by concentrations higher than 20 mM. The total extracellular protein and the extracellular protein per cell ratio were independent of phosphate levels in the culture broth.

摘要

研究了无机磷酸盐浓度对珊瑚状粘球菌D产生抗生素和细胞外蛋白质的影响。这种粘细菌生长细胞产生抗生素的量在磷酸盐浓度为10-20 mM时最大，但高于20 mM的浓度会抑制其产生。细胞外蛋白质总量和每个细胞的细胞外蛋白质比率与培养液中的磷酸盐水平无关。
