Table 1. The correlation between the colony morphology and production of wanlongmycin of wild and mutant type strains.



The type of
strain

Colony morphology of strain

Wanlongmycin
concentration
(µg/ml)

Wild type strain

small, transparent, slippery, and did not produce any colored matter or spores

125.67 ~ 148.95

Mutant type A
strain

large, transparent, slippery, and did not produce any coloring matter or spores

162.14 ~ 271.24

Mutant type B
strain

large, coarse, and produced yellow matter and a few spores

155.68 ~ 238.98

Mutant type C
strain

large, coarse, and produced no colored matter but many spores

146.26 ~ 196.28

Mutant type D
strain

large, coarse, and produced no colored matter and a few spores

105.60 ~ 148.12

Mutant type E
strain

large, coarse, and produced little colored matter and many spores

67.87 ~ 126.35

Fifty strains of every type strain were investigated to ascertain the wanlongmycin production of wild type strain and mutant type strains.
