Optimization of biomass production by autochthonous Pseudomonas sp. MT1A3 as a strategy to apply bioremediation in situ in a chronically hydrocarbon-contaminated soil.

These days, petroleum hydrocarbon pollution has become a global problem, because of this, bioremediation is presented as a strategy for cleaning up sites contaminated with organic pollutants, and it has an increasing role in relation to the potential it presents as a non-invasive and cost-effective...

description These days, petroleum hydrocarbon pollution has become a global problem, because of this, bioremediation is presented as a strategy for cleaning up sites contaminated with organic pollutants, and it has an increasing role in relation to the potential it presents as a non-invasive and cost-effective technology. The aim of this study is to optimize the biomass production of Pseudomonas sp. MT1A3 strain as a soil bioremediation approach for petroleum hydrocarbon polluted environments. Factorial experimental designs were employed to study the effect of several factors of composition medium and incubation conditions on biomass production. Agro-industrial wastes such as peanut oil as carbon source, NaNO3 as nitrogen source and incubation temperature were found to be significant independent variables. These factors were further optimized using Box–Behnken design. Combination of peanut oil 18.69 g/L, NaNO3 2.39 g/L and 26.06 °C incubation temperature was optimum for maximum biomass production of MT1A3 and the model validated in a bioreactor allowed to obtain 9.67g/L. Based on these results, this autochthonous strain was applied in bioaugmentation as a bioremediation strategy through microcosm designs, reaching 93.52% of total hydrocarbon removal at 60 days. This constitutes a promising alternative for hydrocarbon-contaminated soil.
