The effect of different in-vitro temperature were investigated in relation to the growth and production of antibiotic substance by Streptomyces carcinomycicus in order to find out the maximum production of antibiotic substance occurred at 25°C, 30°C and 35°C in vitro temperature. The results of experiment are inconformity with the earlier observations that actinomycetes generally appears to be mesophilic according to the temperature relations.
