Abstract: | Extracellular amylase production by a newly isolated alkali-thermotolerant strain Streptomyces gulbargensis DAS 131 was optimized and characterized. The highest amylase production was achieved by growing S. gulbargensis DAS 131 in media with 1% starch. Strain exhibited maximal activity at pH 9.0 and 45A degrees C and relatively stable in alkaline conditions (pH 11). Starch and peptone were found to be the good source of carbon and nitrogen with a yield of 2,216.6 and 2,156.1 U, respectively. Maltose and maltotriose were the main end products of starch hydrolysis, indicating alpha-amylase activity. SDS-PAGE analysis revealed a monomeric form with a molecular weight of 55 kDa. |
