Abstract
Release of untreated textile effluents, especially into water bodies contributes immensely in making the environment unhealthy, and thereby affecting entire life of humans, plants and other aquatic animals. This eventually affects the quality of water and limits its utilization. This study was carried out to determine some physical and chemical parameters of Challawa textile industrial effluent in Kano, Nigeria. Physicochemical characterization of textile effluents collected from Challawa industrial estates was carried out and the parameters considered in this study were Temperature, pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolve Oxygen and Electrical Conductivity EC . Using morphological and biochemical characteristics, three (3) species of bacteria (Pseudomonasearuginosa, Pseudomonasflourescens and Bacillusmegaterium) were obtained from the central laboratory of Bayero University, Kano for their ability to degrade textile effluents and grow on minimum basal medium efficiently and rapidly. The biodegradation and decolourisations of the bacterial species were carried out for 5 days and the results were expressed in percentages with Pseudomonasearuginosa (99.60%), Pseudomonasflourescens and Bacillusmegaterium (89.00%) The results showed high rates of physicochemical parameters. Analysis of variance of the results revealed that, there was statistically significant differences (p ≤ 0.05) in Temperature, pH and DO after bioremediation. While there was no significant difference in the reduction efficacy of BOD, COD and EC. The selected bacterial species represent a promising tool for application in bioremediation of textile industrial effluents and the biodegradation potential observed would increase the applicability of these microorganisms for treatment of textile effluents before disposal to appropriate channel.
