“…Moreover, these microorganisms can lead to the formation of heteroatom oxidized, N- or O-demethylated and hydroxylated metabolites (Lisowska and Długoński 2003 ; Črešnar and Petrič 2011 ; Zhang et al 1996 ). Data concerning the pathway of carbazole bioconversion by filamentous fungi are still very limited in contrast to the information documenting the degradation ability of different bacteria (Zhao et al 2011 ; Loh and Yu 2000 ; Larentis et al 2011 ; Yoon et al 2002 ). For this reasons we studied ability to carbazole degradation by Cunninghamella strains.…”

“…Nitrogen heterocyclic aromatic compounds are one of the most important classes of the environmental pollutants, which have been detected in air, soil, and water samples (Singh et al 2011a , b ; Xu et al 2006 ). Besides quinolone and pyridine, carbazole is a common contaminant generated from petrochemical and coking industries (Zhao et al 2011 b). This compound contaminates shale oil, crude oil, coal tar, and petroleum distillates (Castorena et al 2006 ).…”

“…The hydrophobic character of the xenobiotic promotes its accumulation in sediment, which may result in its long lasting harmful influence on aquatic organisms (Singh et al 2011b ; Zhao et al 2011 ; Loh and Yu 2000 ). Microbial degradation can be an efficient method for the conversion of dangerous xenobiotics; therefore, a search for microorganisms capable of their utilization and finding the mechanisms of these processes are very important (Xu et al 2006 ).…”

Nitrogen heterocyclic compounds, especially carbazole, quinolone, and pyridine are common types of environmental pollutants. Carbazole has a toxic influence on living organisms, and the knowledge of its persistence and bioconversion in ecosystems is still not complete. There is an increasing interest in detoxification of hazardous xenobiotics by microorganisms. In this study, the ability of three filamentous fungi of the Cunninghamella species to eliminate carbazole was evaluated. The Cunninghamella elegans IM 1785/21Gp and Cunninghamella echinulata IM 2611 strains efficiently removed carbazole. The IM 1785/21Gp and IM 2611 strains converted 93 and 82 % of the initial concentration of the xenobiotic (200 mg L−1) after 120 h incubation. 2-Hydroxycarbazole was for the first time identified as a carbazole metabolite formed by the filamentous fungi of the Cunninghamella species. There was no increase in the toxicity of the postculture extracts toward Artemia franciscana. Moreover, we showed an influence of carbazole on the phospholipid composition of the cells of the tested filamentous fungi, which indicated its harmful effect on the fungal cell membrane. The most significant modification of phospholipid levels after the cultivation of filamentous fungi with the addition of carbazole was showed for IM 1785/21Gp strain.

“…These organisms have been identified by other researchers to be associated with biodegradation [17,18]. Molecular studies on microbial diversity have interestingly been related to degradation potentials of these organisms by various researchers [17,18,19]. The research of [17] examined the degradation of benzo[α]pyrene by a group of bacteria by using the DGGE technique, in order to determine their dynamics during the degradation process, and identified Sphingomonas paucimobilis EPA505, Mycobacterium str.PYR-1, and Alcaligenes denitrificans WW1 to be present in the consortium.…”

In order to strengthen the removal efficiency of heterocyclic nitrogenous compounds in industrial wastewater, a new bacterial strain identified as Bacillus sp. LH-1 was isolated, which could use quinoline as its sole carbon, nitrogen and energy source. The inducing conditions and kinetic properties of quinoline biodegradation by the strain were explored. The results showed that the strain Bacillus sp. LH-1 exhibited maximum tolerance of 700 mgL-1 quinoline concentration. After the strain was activated under the conditions of 200 mgL-1 quinoline for 120 h, the quinoline degradation was triggered, and the quinoline degradation rate increased approximately 10 times, from 2.030mg (L•h)-1 to 21.508 mg (L•h)-1. When the initial concentration of quinoline was 300 mgL-1 , more than 97% quinoline degradation occured within 12 h at pH 7 and at a temperature of 37ºC. The degradation kinetics of quinoline by strain Bacillus sp. LH-1 followed Haldane's model and indicated that the strain isolated in this study could be used for degradation of heterocyclic nitrogenous compounds in industrial wastewater.
