“…An increase of the initial pyridine concentration to 3000 mg L À1 resulted in the complete failure to degrade pyridine. Similar phenomena were also observed by other researchers in the pyridine biodegradation systems [42,43], which could be attributed to the high recalcitrance and high toxicity of pyridine. In addition, the pyridine concentration in raw industrial wastewater was generally in the range of 20-500 mg L À1 [34].…”

“…16S rRNA ampliWcation was described as in a previous study [3], and the sequence was analyzed by an ABI 3730xl DNA analyzer (Applied Biosystems, USA). The result was blasted with other published 16S rRNA sequences by using the BLAST program of the National Center for Biotechnology Information (NCBI) database.…”

A new bacterial strain, Shinella zoogloeoides BC026, which utilizes pyridine as its sole carbon, nitrogen and energy source, was isolated from the activated sludge of a coking wastewater treatment plant. The BC026 strain completely degraded up to 1,806 mg/l of pyridine in 45.5 h. The optimum degradation conditions were pH 8.0 and temperature 30-35 degrees C. According to product monitoring and genetic analysis, the pyridine ring was cleaved between C(2) and N, resulting in 58% of pyridine-N being directly converted into ammonium. Providing glucose as the extra carbon source, the degradation of pyridine was not affected, while the growth of the strain was promoted, and 41% of pyridine-N was converted into ammonium with a C/N ratio of 35. The ammonium was utilized rapidly by the strain, and a portion of it was transformed into nitrate, then to nitrite, and finally to dinitrogen if enough extra carbon was provided. Considering these characteristics, this strain may accomplish heterotrophic nitrification and aerobic denitrification simultaneously.

Pyridine, heterocyclic aromatic compound is known to be toxic, carcinogenic and teratogenic to several living organisms. In this study, two aerobic bacteria ITR-CEM1 and ITRCEM2 capable for pyridine degradation were isolated and characterized as Bacillus cereus (DQ435020) and Alcaligenes faecalis (DQ435021), respectively. For pyridine degradation, mixed bacterial culture was found more effective compared to axenic culture ITRCEM1 and ITRCEM2 degrading 94.23, 67.84, and 83.35% pyridine, respectively, at 144 h incubation period at pH 7.0 ± 0.1, temp 37 ± 2°C and shaking rate 125 rpm in MSM containing 1% glucose and 0.2% peptone as carbon and nitrogen source, respectively. The presence of phenol and formaldehyde in MSM has shown inhibitory effect on pyridine degradation whereas picoline has favored the bacterial growths and pyridine degradation. Further, the HPLC analysis has shown the reduction in peaks compared to controls, indicating that reduction in peak area might be largely attributed to the bacterial degradation of pyridine by bacterial catabolic enzymes.
