Chitinase-producing bacteria were isolated from diseased insect [Pieris brassicae Linnaeus (Lepidoptera: Pieridae) and Spodoptera litura Fabricius (Lepidoptera: Noctuidae)] cadavers. Serratia marcescens strain SEN showed highest enzyme production at temperature 27 °C and pH 9.0 and was selected for further studies. It possessed exochitinase, endochitinase(More)
Bacillus licheniformis strain SSA 61, originally isolated from Sambhar salt lake, was observed to grow even in the presence of 25 % salt stress. Osmoadaptive mechanisms of this halotolerant B. licheniformis strain SSA 61, for long-term survival and growth under salt stress, were determined. Proline was the preferentially accumulated compatible osmolyte.(More)
Bacteria capable of degrading the sulfonated azo dye Red HE7B were isolated from textile mill effluent contaminated soil. The most efficient isolate was identified as Bacillus sp. Azo1 and the isolate could successfully decolorize up to 89 % of the dye. The decolorized cultural extract analyzed by HPLC confirmed degradation. Enzymatic analysis showed(More)
