These pesticides have a negative impact on the soil health and its microbial population. The present investigation was done to evaluate the impact of insecticide Chlorantraniliprole on the total microbial populations, enzymatic activity and various physical parameters (pH, electrical conductivity and organic carbon) in Phaseolus vulgaris cultivated soils. Soil samples were collected before the insecticide spray and on the 3rd, 10th, 20th and 30th day after the insecticide spray from the Phaseolus vulgaris cultivated fields of Singanayakanahalli, Doddaballapur, (Field 1), from fields sprayed with the recommended amount of the pesticide (Field 2) and from field treated with only manure (Field 3) (University of Agricultural Sciences; Bengaluru). Results indicated a significant reduction in the microbial populations and the enzymatic activity. After this initial reduction, ...

Wide range of application of synthetic dyes in industrial and clinical set ups has led to an increased discharge of these dyes into the environment. The dyes being toxic and carcinogenic have to undergo efficient treatment before releasing into the environment. Different physical and chemical methods have been adopted for the treatment of dye effluents. However biological methods are more favoured as they are cost efficient and environment friendly. Most of the biological treatments of dyes rely on microorganisms like bacteria, fungi, algae and yeast. This review aims at providing a detailed account of bacterial degradation of widely used dyes belonging to the class of triphenylmethane dyes.
