Application of low-cost adsorbents for dye removal – A review

Removal of synthetic dyes from wastewaters: a review.

The removal of colour from textile wastewater using whole bacterial cells: a review

A variety of synthetic dyestuffs released by the textile industry pose a threat to environmental safety. Azo dyes account for the majority of all dyestuffs, produced because they are extensively used in the textile, paper, food, leather, cosmetics and pharmaceutical industries. Existing effluent treatment procedures are unable to remove recalcitrant azo dyes completely from effluents because of their color fastness, stability and resistance to degradation. Bacterial decolorization and degradation of azo dyes under certain environmental conditions has gained momentum as a method of treatment, as these are inexpensive, eco-friendly and can be applied to wide range of such dyes. This review mainly focuses on the different mechanisms of decolorization and discusses the effect of various physicochemical parameters on the dye removal efficiency of different bacteria. The enzymatic mechanisms involved in the bacterial degradation of azo dyes, the identification of metabolites by using various analytical techniques, and the nature of their toxicity has been investigated. This review provides an overview of bacterial decolorization/degradation of azo dyes and emphasizes the application of these processes for the treatment of azo dye-containing wastewaters.

Thermostable alkaline protease from bacillus brevis and its characterization as a laundry detergent additive

Culture-based methods are important in investigating the microbial ecology of natural and anthropogenically impacted environments, but they are extremely biased in their evaluation of microbial genetic diversity by selecting a particular population of microorganisms. With recent advances in genomics and sequencing technologies, microbial community analyses using culture-independent molecular techniques have initiated a new era of microbial ecology. Molecular analyses of environmental communities have revealed that the cultivable fraction represents <1% of the total number of prokaryotic species present in any given sample. A variety of molecular methods based on direct isolation and analysis of nucleic acids, proteins, and lipids from environmental samples have been discovered and revealed structural and functional information about microbial communities. Molecular approaches such as genetic fingerprinting, metagenomics, metaproteomics, metatranscriptomics, and proteogenomics are vital for discovering and characterizing the vast microbial diversity and understanding their interactions with biotic and abiotic environmental factors. This chapter summarizes recent progress in the area of molecular microbial ecology with an emphasis on novel techniques and approaches that offer new insights into the phylogenetic and functional diversity of microbial assemblages. The advantages and pitfalls of commonly used molecular methods to investigate microbial communities are discussed. The potential applications of each molecular technique and how they can be combined for a greater comprehensive assessment of microbial diversity has been illustrated with example studies.
