D. Roy et al., ANILINE DEGRADATION IN A SOIL SLURRY BIOREACTOR, Journal of environmental science and health. Part A: Environmental science and engineering, 32(8), 1997, pp. 2367-2377
This research was designed to determine the feasibility of the biodegr
adation of aniline in a soil slurry system. Microorganisms isolated fr
om an aniline-contaminated site were classified to be Achromobacter xy
losoxidans and a Pseudomonas species. A mixed culture of bacteria was
observed to grow on aniline as the only source of carbon. Studies cond
ucted in liquid media demonstrated simultaneous oxygen uptake and anil
ine removal at a concentration of 700 mg/L. The optimum pH for the bio
degradation of aniline by the classified microorganisms in liquid medi
a at a concentration of 700 ppm was determined to be between pH 7 and
pH 8. Biodegradation studies were conducted in soil slurry system usin
g soil similar to that at the aniline-contaminated site. These studies
investigated the role of abiotic processes in the removal of aniline,
the ability of indigenous microorganisms to degrade aniline, and the
effect of amendment with an acclimated bacterial population and the ad
dition of nutrients. The ability of aniline to serve as a sole source
of nitrogen and carbon was also investigated.
