“…Similar results were observed in various reported microorganisms [31,32]. Our data indicates that the studied alkaliphile, Bacillus badius D1 strain can degrade aniline more efficiently than the earlier reported neutrophilic bacteria [33][34]. The degradation rate of aniline was found to be varied with various pH ranging from 7.0 to 11.0.…”

“…Anilines being organic derivatives, in which hydrogen atoms from the aromatic cycle are replaced by organic radicals, have a toxic influence on living organisms in aquatic basins 22 , 32 , 33 . The studied aromatic amines by analogy could be considered as well toxic to aquatic microorganisms.…”

The toxic effects of ammonium derivatives in the river water depend dramatically on their natural or synthetic origins and on their chemical structures. It has been proved that 1-naphtylamine (1-NA) and diphenylamine (DPA) breaking impact on the ammonium oxidation and especially on nitrite ions oxidation processes in natural waters is associated with its toxicity. The NH4+ oxidation process slows down for about five days and ten days in river water samples with 0.5 mg/L DPA and corresponding 0.5 mg/L 1-NA. The NO2− oxidation delay in model samples of river water with 0.025 and 0.05 mg/L 1-NA, is four days and 35 days in the one with 0.5 mg/L 1-NA. For the sample with 0.05 mg/L DPA the delay of the NO2− oxidation is approximately of six days and 25 days for sample with 0.5 mg/L, DPA. The laboratory simulations have revealed: (1) absorption–desorption, the micro biotic reaction to the instantaneous increase of the concentration of ammonium ion in the river water (so-called shock/stress effect) and (2) the NH4+ increase stimulated by a certain (0.05 mg/L) concentration of 1-NA.The diethylamine (DEA) decomposition leads to increasing with approximately 3.8 mg/L NH4+ in river water samples of 20.0 mg/L DEA.

“…The bacterial species of Pseudomonas (Kahng et al, 2000a;Tanaka et al, 2009), Comamonas (Boon et al, 2000), Rhodococcus (Zhuang et al, 2007), Acinetobacter (Wyndham, 1986), Frateuria (Murakami et al, 2003), Moraxella (Zeyer et al, 1985), Delftia (Kahng et al, 2000a;Zhang et al, 2008) and Nocardia (Wang et al, 2006) have been shown to be efficient degraders of aniline and its derivatives (Liu et al, 2002). These bacteria showed the ability to efficiently biodegrade aniline under neutral and moderate conditions (Li et al, 2010) and up till now, aerobic biological treatment was reported to remove aniline efficiently (Chengbin et al, 2009;Takeo et al, 1998b;Zhang et al, 2008).…”

Aromatic amines are potential mutagens and carcinogens, so biodegradation of them may protect our environment by safely getting rid of these compounds. In the present study, 5 aniline degrading isolates were recovered from 30 samples of sewage and agricultural wastewater, The five isolates were identified biochemically and by 16S rRNA gene sequence analysis as Achromobacter sp. (2 isolates), Pseudomonas sp. (2 isolates) and Enterobacter sp. (1 isolate). Biodegradation of aniline was measured by HPLC, and within 10 days, aniline degradation percentage was variable ranging from 27% to 61% of the initial aniline concentration with the formation of catechol as the byproduct which was further biodegraded to cis, cis muconic acid confirming that the isolate was following the ortho-cleavage pathway. Additionally, the ability of these isolates to degrade aniline was confirmed by measuring the optical density (OD) of the growth of the five isolates in the presence of aniline as sole carbon source using the microtiter plate method at 620 nm. The genomic DNA and plasmid of the isolates were then extracted. Screening for selected genes, known to encode aniline depredating enzymes; cat1,2, cat2,3, tadR, and tdnQ using PCR was done. It revealed the presence of cat1,2, tadR, and tdnQ in the plasmid preparation. Significance, and Impact of study: It was concluded that aniline is degraded by the five isolates through a pathway involving enzymes performing ortho-cleavage of the benzene ring and these isolates could have a potential role for use in bioremediation of aniline contaminated environments.
