Abstract

The effect of bacteria on crude oil degradation in loamy and clay soil for water and ethanol biostimulant extraction from Bryophylum pinnatum leaf was investigated to ascertain the potential of the bacteria counts in the bioreactors sampled. At the progressive phase, the bacteria counts were more with bioreactors induced with ethanol solvent extract as the volume of the dosage increases compared to the bioreactors induced with the water extract. The research revealed that the bacteria growth was not induced by any factor at the progressive stage of the process, however a rapid increase in bacteria was experienced with increase in TPH degradation in each of the bioreactors. The biostimulant used in this investigation has revealed its potential in mitigating and restoration of a contaminated site by the application of solvent extraction techniques and approach of bioremediation concept. However, the bacteria counts were more on loamy soil with increase in ethanol application of solvent extraction compared to water application of solvent extracts, as well as in the case of clay soil, the same trend of characteristics was followed. But the bacteria count in clay soil was low compared to the loamy soil and this characteristic was attributed to the porosity of the soil type.
