Synthesis and antibacterial activities of new dibenzothiazepine derivatives
1196-1201A number of substituted
dibenzo[b,f][1,4]thiazepines
analogues carrying heterocyclic and aliphatic moiety attached to C-11 position
have been synthesized and evaluated their antibacterial activities against gram positive and gram negative
bacteria. Derivatives of imidazole, 2-methyl imidazole and pyrrolidine exhibit
significant antibacterial activities
Decolorization and biodegradation of azo dye, reactive blue 59 by aerobic granules
The present study deals with development of aerobic granules from textile wastewater sludge and challenged with different concentration of reactive blue 59 (RB59) to test their dye degradation potential. The granules efficiently degraded reactive blue 59 and also sustained higher dye loading of up to 5.0 g l−1. The significant induction of enzymes azoreductase and cytochrome P-450 indicated their prominent role in the dye degradation while genotoxicity studies demonstrated that the biotransformed product of the dye as non-toxic. The microbial community of the textile dyes degrading aerobic sludge granules analyzed by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE), revealed significantly diverse dye degrading microbial community belonging to alpha-, beta-, and gamma-proteobacteria
