Seventeen
strains of
actinomycetes antagonistic to
yeast and moulds have been tested for their
ability to produce
amylase,
lipase,
gelatinase and caseinase using solid media containing
starch,
Tween-20,
gelatin and skimmed
milk, respectively,
Enzyme producing potential of test
strains is expressed in ternis of relative
enzyme activity (REA).
Actinomycetes strain Streptomyces somaliensis GS 1242 and
Streptomyces sampsonii GS 1322 showed higher
amylase production (REA 6.5) while maximum
lipase activity was noted in
Streptomyces strain SAP 1089 (REA 7.0).
Gelatinase activity was noted higher is S. sampsonii GS 1322 (REA 9.6) and S. somaliensis GS 1242 (REA 8.8).
Enzyme producing potential of these
strains has been discussed in terms of their industrial significance.
