Effect of remediation strategy on crude oil biodegradation kinetics and half life times in shoreline sediment samples

effect of remediation strategy on crude oil biodegradation kinetics and half life times in shoreline sediment samples

bioremediation, the process by which microorganisms degrade organic compounds to non-toxic or less toxic substances, has been widely used for cleanup of coastal ecosystems after oil spills. in this study, the hydrocarbon degradation rate and half lives in three bioremediation strategies (natural attenuation, biostimulation, and bioaugmentation) were compared in weathered crude oil (wco) contami...

Effect of Salinity, Temperature, pH and Crude Oil Concentration on Biodegradation of Crude Oil by Pseudomonas aeruginosa

The present study was carried out to evaluate the effect of culture conditions on biodegradation of crude oil by Pseudomonas aeruginosa. P. aeruginosa was isolated from sea water using Bushnell Haas agar supplemented with 0.1% crude oil. The strain was cultured at different temperature, pH a salinity and crude oil concentrations. Maximum growth and biodegradation occurred at 38C, pH 8.0, 35‰ an...

Effect of Crude Soybean Oil Sediment as a Substitute for Refined Soybean Oil in Broiler Diet

Four hundred fifty day old unsexed broiler chicks were used in a 35-day trial at Chittagong veterinary and animal sciences university farm to find out the effect of using crude soybean oil sediment (CSOS) as a substitute for refined soybean oil (RSO) in broiler diet. The experiment was carried out following completely randomized design. The chicks were randomly distributed in three treatment gr...
