“…strain SMN-1 degraded 2-nitrotoluene through 3-methylcatechol by a meta-cleavage pathway, with release of nitrite. The results are in agreement with the results of Loidl et al (1990) and Sutherland et al (1981) who found that aniline and benzoic were degraded via ortho pathway. A new UV spectrum at 257 nm which may be β-carboxy -muconate was detected in enzyme reaction products of protocatechuic acid as substrate with catechol 1,2-dioxygenase enzyme (Ornston and Stanier, 1966).…”

Corynebacterium sp was isolated from the soil by using 3-5 dinitro benzoic acid (DNB) as a sole carbon source. The highest rate of degradation of aniline (AN) or DNB was found in the exponential phase of the growth of the bacterium. After 24 h, about 50% of DNB and 30% of AN were degraded by Corynebacterium sp. At a concentration of 0.5 to 1 g/L of AN or DNB, good growth was obtained and the protocatechuic acid was detected. The optimum concentration of yeast extract was 2 g/l. Catechol 1-2 dioxygenase was induced in the cells grown on a medium containing AN or DNB. A significant activity of this enzyme was detected, which means that ortho cleavage pathway may be present in Corynebacterium sp.

“…Conversion of DNB and AN to brown coloured oxygenated products was reported by Parris (1980). Polymerization of highly reactive catechol or protocatechute was reported also by Loidl et al (1990) and Bachofer et al (1975); it may give a reason for the accumulation of the brownish product.…”

“…3,7) Recently, many studies on aniline mainly focused on biodegradability, metabolic pathway by pure culture of microorganisms and removal of aniline in wastewater treatment systems. [8][9][10][11][12][13][14] Studies researching into the degradation of aniline by bacteria as the sole source of carbon have been done by many researchers. 4,8) However, few studies have focused on the processes and degradation ability of bacteria to utilize aniline as the sole source of nitrogen.…”

“…Anilines are metabolized to the corresponding catechols via one or more oxidative reactions catalyzed by aniline dioxygenases, liberating ammonia and subsequently undergoing metabolic transformations (Liodl et al, 1990;Fuchs et al, 1991). Bacterial degradation of aromatic compounds has frequently been shown to be plasmid encoded (Chakrabarty, 1976).…”

Aniline, a serious environmental threat and health risk to living organisms is being released into the soil and water bodies owing to its expanded use in industry. The objective of the present study was to isolate a strain from rhizospheric soil samples of wheat (Triticum aestivum L.) taken from an agricultural site near the industrial area of Faisalabad, with the capability of degrading aniline with its maximum activity. The isolated strain was identified as Staphylococcus aureus ST1 a newly reported strain for aniline degradation. The strain ST1 showed tolerance up to 2000 ppm for aniline on mineral salt media plates and its degradative ability was checked through shake flasks experiments using HPLC. The strain was capable of degrading aniline and utilizing it as a sole source of carbon and energy. Maximum reduction of aniline concentration in medium up to 59.65% was observed after 72 h. An enhancement in biodegradation was observed using glucose as an additional growth substrate. The degradative products analyzed by HPLC were catechol, phenol and some other unknown compounds. Plasmid curing showed the involvement of plasmid encoded genes which was later followed by the isolation of plasmid DNA, which was found to be a large one of ~40 kb having restriction sites for enzymes (EcoRI, BamHI, ClaI, StuI, PstI, and HindIII) used.
