amylase,, Polyextremophiles, mango pickle, Bacillus megaterium.Abstract
An organism having ability to produce extracellular salt stable and thermostable amylase was isolated from mango pickle. Identification of the bacterium was done based upon morphological and biochemical tests as Bacillus megaterium. Further this strain was screened for the amylolytic activity in presence of salt using starch agar plates with 11 % NaCl and results indicated that it was amylase producer. It has produced 1.63 U/ml of polyextremophilic amylase. Highest catalytic activity of the enzyme was recorded at temperature of 60°C and pH 9 and enzyme remained stable with 11% salt concentration.
