Determination of alpha-amylase activity of Streptomyces spp isolated from Bangladeshi soils.

Streptomyces, the largest genus of actinobacteria, is a group of bacteria which is most commonly isolated from soil. In this study, total 24 indigenous Streptomyces spp. were isolated from soil samples collected from different parts of Bangladesh Of them, two species designated as S-31 and S-109 were studied to determine their alpha-amylase activity. The α-amylase activity of S-31 and S-109 was 2.26 unit/ml and 2.67 unit/ml .Based on this study, it can be concluded that both species of Streptomyces were good candidate for amylase production.
