“…Aniline concentration was dropped from 100 to 4.0 mg l -1 within 7 days especially at pH 7.0, which mean that the biodegradation efficiency could reach as high as 96%. The results are consistent with previous studies which have found that most degrading bacteria, such as Candida tropicalis AN1 (Wang et al, 2011) and Frateuria (Murakumi et al, 1999), could degrade aniline at a narrow pH range of 6.0 and 8.0. Degradation of aniline also reached the maximal values at a range of temperature levels between 28 to 35 °C.…”

“…On the contrary, the aniline degradation declined sharply when the temperature dropped to 20 °C and under, indicating that the lower temperature is not beneficial for the biodegradation of aniline by the strain KH-A5. These growth conditions of E. ludwigii KH-A5 for aniline degradation were similar those of other bacteria reported previously (Wang et al, 2011;Sarwade and Gawai, 2014).…”

Aniline is a harmful substance that pollutes the environment and seriously endangers human health. In the present study five different bacteria were enriched and isolated from the soil around Shiraz refinery (Iran) as aniline degrading bacteria. They were identified as Enterobacter ludwigii KH-A5, Raoultella planticola KH-A2, Alcaligenes faecalis KH-A3, Serratia marcescens KH-A4 and Microbacterium barkeri KH-A1 based on 16S rDNA gene sequencing. The highest aniline degradation rate (96%) was observed by E. ludwigii KH-A5. This strain with the greatest amount of minimum inhibitory concentration (MIC) was the most aniline resistant bacterium. The optimum pH and temperature that supported biodegradation of aniline by strain KH-A5 were 7.0 and 28-35 °C, respectively. The maximum growth and biodegradation of aniline by KH-A5 were observed at the initial aniline concentration of 100 mg l -1. The strain could growth on aniline up to concentration of 700 mg l -1 with the degradation rate of 11%. Further studies demonstrated that the addition of 0.5 g l -1 glucose or potassium nitrate as a second carbon or nitrogen source could slightly enhance the biodegradation efficiency from 96.0% to 99.0%. However, even more addition of glucose or potassium nitrate could not further enhance the biodegradation process but delayed the biodegradation of aniline by the strain KH-A5. It could be concluded that these new strains, particularly E. ludwigii KH-A5, have a potential use for bioremediation of the site contaminated with aniline.

“…strain F3 was used to evaluate naphthalene degradation in petroleum-contaminated soil and a reduction of 61.11% in initial concentration was observed [32]. Kafilzadeh and Khezri [39] revealed that E. ludwigii KH-A5 showed highest degradation rate (96%) which is likely to be due to high levels of enzyme production responsible for aniline biodegradation under favourable growth conditions, similar to those of other bacteria reported previously [40,41].…”

A bacterial strain has been isolated from petroleum contaminated soil with in southeastern Turkey. This isolated strain was characterized to determine its hydrocarbon biodegradation potential. Phenotypic features and of 16 S gene sequence analysis of rRNA revealed that strain D8 belongs to the Enterobacter genus and most closely resembles Enterobacter ludwigii (100%). The optimum temperature and pH values for the growth of E. ludwigii D8 were found to be 30°C and 5.0, respectively. This bacterial strain grew in long and medium chain hydrocarbons such as 1% decane, pentadecane and squalene separately at the end of 3 day incubation in the basal medium (BM) under optimum conditions. It was shown that E. ludwigii strain D8 degrades about 27% of crude oil incubated for 5 days, while it degrades 29% of pentadecane after 3 days of incubation determined by Gas chromatography-MS analysis. The biodegradation potential of petroleum hydrocarbons of E. ludwigii strain D8 isolated and characterized in this study indicates that this strain may play a role in the bioremediation process.

Aniline is a toxic aromatic compound causing environmental pollution, especially water problems, which harmfully affect to human and aquatic species. Seven bacterial strains were isolated from the sewerage of biological and chemical laboratories using aniline as a sole carbon and nitrogen source. Among them, Pseudomonas moraviensis AN-5 showed the highest efficiency. The aniline-degrading P. moraviensis AN-5 utilized aniline completely after 3 days at concentrations ≤ 4.0 mM. The addition of yeast extract and succinate stimulated the growth and aniline degradation of the strain. The investigation of aniline degraration pathway of P. moraviensis AN-5 showed that aniline was degraded by AN-5 via the ortho-clevage pathway.
