Out of the nine isolated actinomycetes
screened for antimicrobial activity against five
bacterial and three fungal strains by agar
streak method, six, namely, A1, A2, A3, A4,
A5 and A6 showed significant antimicrobial
activity against both Gram-positive and
Gram-negative organisms. However, A4
showed a very broad spectrum with the
highest scores (Table 2).
development of actinomycetes populations in
the soil [3-7]. The presence of relatively large
populations of actinomycetes in the soil
samples of Belgaum indicates that it is a
suitable ecosystem that promotes the
isolation of actinomycetes during screening
programmes.
