Study of Environmental Conditions on Protease Production by Bacillus sp. from Lignite Mine of Gujarat

Varjani Sunita J

Abstract :

The major cause of acid mine dranage (AMD) or acid rock drainage (ARD) is mining activities of lignite and metal sulphidic mines. The harsh environmental conditions in terms of pH, iron, metals and dissolved solids are responsible for damage of surrounding aquatic and terrestrial ecosystem. Lignite mine ARD of Panandhro showed pH 2.0. Proteases are class of enzymes, which occupy key position in various commercial fields. Protease producing gram positive bacterial isolate belonging to genus Bacillus was isolated from this extreme ecosystem and was used for protease production study under environmental parameters such as aeration and agitation, medium pH and incubation temperature. The isolate showed optimum growth in well aerated condition. The optimum pH and temperature were 7.2 and 37°C, respectively
