Physicochemical properties and biodegradability of crude oil

Article Abstract:

The degradation of crude oil by microbacteria is one of the natural ways to decontaminate accidental spillages of petroleum, whose components are grouped into the saturates, the aromatics, the resins, and the asphaltenes. Results of observations on four crude oil samples (Arabian light, Dubai, Maya and Shengli) by the SM8 and Acinobacter bacteria show that the degree of biodegration of petroleum components was different in each sample. The saturated portion of the samples were also more biodegradable than the aromatic fractions.

Use of benzoate to establish reactive buffer zones for enhanced attenuation of BTX migration: aquifer column experiments

Article Abstract:

Evaluation of benzoate used as a cosubstrate for benzene, toluene and o-xylene (BTX) aerobic degradation reveals that the compound may be used to establish and sustain in situ reactive zones. Benzoate has been found to enhance BTX degradation kinetics and attenuate BTX breakthrough in aquifer columns. The study also evaluates the feasibility of injecting benzoate as BTX degrader growth enhancer and buffer zone former.
