Isolation and Characterization of Bacteria of Amnura and Baliadangi soil series of Bangladesh

Bacteria, single celled and ancient form of life, are living in any condition. Their isolation and identification are important for their classification. This study was for isolation and characterization of bacteria from Amnura and Baliadangi soil series. Isolated colonies of bacteria were evaluated in size, pigmentation, form, margin and elevation. It has been observed that Baliadangi soil was found to have more bacterial population than that of Amnura soil. From simple and negative staining, shape and arrangement were determined. Majority of the bacteria were Gram- negative, spore forming and capsuled. The presence of rod shaped bacteria (Bacillus) compared to round shaped (Coccus) in soils is a finding.
