“…These microorganisms include Bacillus sp., B. subtilis IS13, (Niazi et al 2001;Andretta et al 2004), Pseudomonas sp., P. veronii, P. fluorescens, (Thakur et al 2002;Nam et al 2003;Shah and Thakur 2003), and P. aeruginosa Shah and Thakur (2003); Premalatha and Rajkumar (1994), Flavobacterium (Saber and Crawford 1985), Sphingomonas chlorophenolica ATCC 39723 (Xun et al 1999), Desulfomonile tiejei DCB-1 (Mohn and Kennedy 1992), Arthrobacter chlorophinolicus A6 (Agneta et al 2004). Recently we have reported two aerobic bacterial strains namely Bacillus cereus (DQ002384), ITRC S 6 and Serratia marcescens (AY927692), ITRC S 7 (Chandra et al 2006b) which have been shown to marked degradation of PCP in mineral salt medium in presence of glucose and peptone.…”

Two PCP-degrading bacterial strains, Bacillus cereus (ITRC-S6) and Serratia marcescens (ITRC-S7) were used for the treatment of pulp and paper mill effluent at conditions; 1.0% glucose and 0.5% peptone at 30 +/- 1 degrees C at 120 rpm for 168 h of incubation. These two bacterial strains effectively reduced colour (45-52%), lignin (30-42%), BOD (40-70%), COD (50-60%), total phenol (32-40%) and PCP (85-90%) within 168 h of incubation. However, the highest reduction in colour (62%), lignin (54%), BOD (70%), COD (90%), total phenol (90%) and PCP (100%) was recorded by mixed culture treatment. The bacterial mechanism for the degradation of pulp and paper mill effluent may be explained by an increase in the cells biomass using added co-substrates resulting liberation of significant amount of chloride due to bacterial dechlorination of chlorolignins and chlorophenols this showed reduction in colour, lignin and toxicity in the effluent. Further, GC-MS analysis of ethyl acetate-extractable compounds from treated pulp paper mill effluent reinforces the bacterium capability for the degradation of lignin and pentachlorophenol, as many aromatic compounds such as 2-chlorophenol, 2, 4, 6-trichlorophenol and tetrachlorohydroquinone, 6-chlorohydroxyquinol and tetrachlorohydroquinone detected which were not present in the untreated effluent.

“…Andretta et al 24 described that for 4,5,6‐trichloroguaiacol degradation by Bacillus subtilis the growth phase was important, differently than that observed in propanil degradation by E. cloacae . Only the stationary phase inoculums caused degradation because the higher biomass induced a rapid decrease in glucose, producing equilibrium between the concentrations of glucose and the xenobiotic, triggering the biodegradation process.…”

“…Some culture mediums were evaluated aiming to extend the time of cell viability and to facilitate the monitoring of degradation by HPLC, since culture mediums containing yeast extract (peptone or tryptone) can difficult the HPLC analysis. Among the culture mediums evaluated were those used by Nawab et al 23 and Andretta et al 24, which could be used for the HPLC analysis but did not increase cell viability. It was not possible to find any medium able to extend the survival of the RR01.…”

Biodegradation of Herbicide Propanil and Its Subproduct 3,4‐Dichloroaniline in Water

The rational use of pesticides generates an impact which is normally reversed and eliminated by the environment itself. However, the indiscriminate use of pesticides makes its natural degradation rhythm difficult, prolonging their presence in the soil for a great deal of time. Aiming towards a decrease in the environmental impact of pesticides, soil microorganisms capable of degrading pesticides, such as propanil, were investigated. An Enterobacter cloacae strain, isolated from rice field soil, was exposed to the herbicide propanil alone and in a mixture containing also bentazone, clomazone, quinclorac, and 2,4-D. This bacterium was able to eliminate 100% of the applied propanil in 28 days. Propanil degradation in the 5-herbicide mixture was much lower than that of individual pesticide degradation. The aeration of the system helped to degrade propanil and its subproduct 3,4-dichloroaniline much faster. LC with UV detection was used to determine the remaining concentrations of the herbicides and their subproducts.

“…More recently, Rhodococcus aetherivorans strain M8 was shown to degrade cyclic ether tetrahydrofuran (Tajima et al 2011). The fact that Bacillus species can withstand harsh environments due to their resistant spores has made them a perfect candidate for removing pollutants in the environment (Andretta et al 2004). Members of the genus Stenotrophomonas can be found in soil, and several species have been associated with biodegradation of xenobiotic compounds such as herbicides, insecticides, and keratin (Ryan et al 2009).…”

In this study, 11 bacteria isolated from Tapis crude oil-contaminated sites were identified by using biochemical tests and 16S rDNA gene sequencing. Their abilities to biodegrade Tapis crude oil was determined by gas chromatography before they were further screened for biosurfactant activity by employing qualitative (blood agar hemolysis, microplate assay, drop-collapse test), semiquantitative (emulsification formation), and quantitative (surface tension measurement) methods. Four isolates, namely, Acinetobacter baumanii UKMP-12T, Pseudomonas aeruginosa UKMP-14T, Rhodococcus sp. UKMP-5T, and Rhodococcus sp. UKMP-7T, exhibited high percentages in total petroleum hydrocarbon (TPH) degradation. A strong correlation between the emulsification index (E 24 ) and surface tension measurement (r s = +.866) as shown by Spearman rank correlation analysis suggested that these two methods were more reliable to predict biosurfactant activity. The TPH removal was also positively correlated to the ability of bacterial isolates to reduce the surface tension of growth medium, as revealed by Pearson correlation test (r p = +.886). In conclusion, not all the biosurfactant detection protocols employed were effective. Nevertheless, the measurement of surface tension and E 24 determination provided a rather rapid, easy, reproducible, and accurate result in identifying bacteria with biosurfactant-producing ability.
