Naphthalene degradation by Pseudomonas sp. HOB1: in vitro studies and assessment of naphthalene degradation efficiency in simulated microcosms.
Journal of Hazardous Materials, 2009Co-Authors: Hilor Pathak, Datasha Kantharia, Ankita Malpani, Datta MadamwarAbstract:Abstract Naphthalene, being a ubiquitous pollutant of the environment and a perilous material, its biodegradation has been receiving constant Scientific Consideration. Highly potential, naphthalene degrading bacteria were isolated from sediments of polluted Amlakadi canal, Gujarat, India. Among the isolates, Pseudomonas sp. HOB1, showed ability to degrade 2000 ppm naphthalene within 24 h. The culture exhibited potential to tolerate as high as 60,000 ppm of naphthalene. Statistical approach was used to analyze the effect of physiological parameters and initial biomass concentration on naphthalene degradation. Naphthalene degradation was found to be augmented in the pH range of 7.5–8.5. Naphthalene degradation was maximum in the temperature range of 35–37 °C and initial inoculum size of more than 1.8 ml of 1.0 A660. Simulated microcosm studies in the presence and absence of indigenous microflora confirmed its ability for naphthalene degradation and to colonize the soil. Pseudomonas sp. HOB1 was found to be highly potent in degrading higher concentrations of naphthalene under laboratory conditions as well as in simulated microcosms.

in vitro studies on degradation of synthetic dye mixture by comamonas sp vs mh2 and evaluation of its efficacy using simulated microcosm
Bioresource Technology, 2011Co-Authors: Hilor Pathak, Meeta Rathod, Sonal Patel, Kishor ChauhanAbstract:Abstract Reactive azo dyes are considered as one of the most detrimental pollutants from industrial effluents and therefore their biodegradation is receiving constant Scientific Consideration. A bacterial isolate VS-MH2, originating from dye contaminated sites of Gujarat, India, was exploited for its ability to degrade a synthetic dye mixture (SDM) (comprising of four azo reactive dyes) under static conditions. The identification of the isolate by 16S rRNA gene sequencing revealed it to be Comamonas sp. The biodegradation of the SDM was analyzed by UV–vis spectroscopy, IR spectroscopy and GC–MS analysis. The isolate showed high metabolic activity towards SDM and degraded it completely (100 mg L −1 ) within 30 h at pH 7 and 35 °C. Simulated microcosm studies in the presence and absence of indigenous microflora confirmed the ability of Comamonas sp. VS-MH2 for dye degradation and to colonize the soil. This is the first investigation reporting the degradation of SDM by Comamonas sp. under simulated soil microcosms.
