Abstract
The object of this paper is to determine the optimum pH for the production of earthy-musty odor substances on Actinomycetes. Mikawa A strain (Streptomyces griseofuscus) and Biwako B strain (S. resistomycificus var.) were incubated and shaked. Since the pH values of these medium changed, they were controlled by adjustment during the incubation and shaking. It was concluded that the optimum pH of Mikawa A strain was between pH 5.4 and 7 and of Biwako B strain was between pH 5 and 6. The optimum pH of these Actinomycetes were different from that of Cyanobacterium, Phormidium tenue, between pH 8 and 9.This publication has 0 references indexed in Scilit:
