Production of thermo stable alkaline xylanase from Bacillus species

S.Sridevi, Sandhya, G.Narasimha

The aim of the present study is to determine the effect of cultural conditions on the xylanase production from Bacillus sps isolated fromsoil contaminatedwith cottonmill industrial effluents of Chittoor,A.P., India, when grown on liquid media with rice bran,grass, corn cob and sugarcane baggage as carbon sources. Among the carbohydrates used in the study, glucose is found to be best inducer for xylanase production by Bacillus sps. Yeast extract and potassium dihydrogen phosphate were found to be best nitrogen and phosphorous sources for optimum xylanase production by the bacterial isolate at temperature 50ï‚°C with pH 9.
