Abstract: New strains with higher penicillin G and V production were isolated using mutagenic factors in mutual combination. Penicillin production by these strains depended upon the C source in the medium. Individual strains reacted differently to the change of C source. In the absence of precursors, the strains produced a different no. of natural penicillins. A direct relation between increasing production of penicillins and the concn. of 6-aminopenicillanic acid in the filtrate was not established.
