Significance and Impact of the Study: This study presents a bacterial consortium consisting of Rhodococcus sp.T3-1, Delftia sp.T3-6 and Sphingobium sp.MEA3-1 could completely mineralize acetochlor by biochemical cooperation. The study reveals the metabolic mechanism of acetochlor biodegradation and highlights the potential of the bacterial consortium for cleaning up acetochlor and its metabolites subsisting in the environment. AbstractOwing to acetochlor persistence in the environment and its perceptible threats to the ecosystem and human health, it is urgent to search for effective approaches to decontaminate acetochlor. In this study, an acetochlor-degrading enrichment culture was obtained by continuous enrichment from acetochlorcontaminated soil and named T3. T3 could completely degrade 100 mg l À1 acetochlor and butachlor within 6 days. Two bacterial strains Rhodococcus sp.T3-1 and Delftia sp.T3-6 and one strain Sphingobium sp.MEA3-1 were isolated and identified from T3 by using acetochlor and MEA as sole carbon source, respectively. These three bacteria could completely mineralize acetochlor by the cooperative metabolism. The biochemical pathway of acetochlor degradation by these three bacteria in a consortium was proposed: acetochlor to 2 0 -methyl-6 0 -ethyl-2-chloroacetanilide (CMEPA) by Rhodococcus sp. T3-1, CMEPA to 2-methyl-6-ethyl aniline (MEA) by Delftia sp.T3-6 and MEA by Sphingobium sp.MEA3-1 based on the identified degradation intermediates. Under laboratory conditions, the consortium was effective in the acetochlor mineralization.

“…The presence of aniline in the environment is potential threat to living organisms. The degradation of aniline by neutrophilic bacteria have been studied by various reporters [25][26][27]. The degradation of aniline in alkaline conditions were earlier reported [28,29], still the degradation of aniline by Bacillus badius D1 can't be compared with it due to little different experimental condition.…”

Aniline and its derivatives are common environmental pollutants formed by incomplete degradation of some pesticides (linuron and propanid) in soil (Sheludchenko et al 2004). The small scale greenhouse activity around the lake would provide source for the bacteria in the sediments.…”

Small artificial lakes are ubiquitous in various natural environments. Small impoundments increase the residence time of water, thereby increasing the potential for retention of nutrients through biological and physical processes. We examined bacterial community structure of Lake Maslak, a small freshwater impoundment located in a densely populated region. The objective of our study was to investigate bacterial communities of the lake sediment which has not been determined and to elucidate the factors controlling bacterial diversity and the biogeochemical processes within the lake. For these purposes, surface water, lake bed sediments, and one core sample were collected. Microbiological characteristic of the lake bed and core sediments was determined by denaturing gradient gel electrophoresis targeting the 16S rRNA gene. Along with the microbiological studies, physicochemical (O(2), pH, temperature) and geochemical properties of the surface (NO (3) (-) , NO (2) (-) , NH (4) (+) ,PO (4) (-) ,SO (4) (2-) , K(+), Mg(2+), Ca(2+)) and pore water (K(+), Mg(2+), Ca(2+)) were determined in addition to heavy metals contents (Co Cu, Fe, Zn, Pb, Cd). Eight lake bed and one core sediments were also collected and analyzed for heavy metals and elemental compositions. Nitrate concentration in the surface water ranges from 0.27-1.8 mg/L, and ammonium (0.0-0.83 mg/L) appears to follow nitrate concentration. Sulfate concentration in the surface water (mean 60 mg/L) is greater than those measured in the pore water (mean, 37.5 mg/L). Fe, Zn, Pb, and Cd were not determined in the surface water, whereas Co was significantly higher both in the surface and pore water. Unlike Co, Pb, Zn, and Cd were not measured in the pore water. Lakebed and core sediments show significant enrichment in Pb, Zn, and Cu, indicating anthropogenic pollution. Consistent with geochemical parameters, microbiological analysis suggests a diverse bacterial community in the lake sediments and influence of anthropogenic pollution (e.g., atmospheric emission) on bacterial community.
