Abstract
The aim of work was to check and make comparison of efficacy for five approaches for petroleum crude contaminated agricultural soil remediation by making use of soil microcosms. Concerning the published literature in our information, this is the first report comparing five approaches i.e. abiotic losses, native microbial flora, nutrient amendments and pre-adapted native microbial culture and concurrent amendments of nutrients + pre-adapted native microbial culture for agricultural soil bioremediation using Pseudomonas aeruginosa NCIM 5514 by performing soil microcosm experiments. 96.00 ± 0.18% degradation of petroleum hydrocarbon fractions in 60 days of the experiment was observed when nutrients and P. aeruginosa NCIM 5514 were applied concomitantly. In nutrients- and P. aeruginosa NCIM 5514-added microcosm reduction in nitrogen, organic carbon, and phosphorus was noted. P. aeruginosa NCIM 5514, can be applied as a prospective bioremediation agent to remediate petroleum crude contaminated soil.
