“…These results suggest that an ortho cleavage pathway may be present in this strain. Contrary to our results, Bae et al (1996) and Liu et al (2002) found that the degradation of aniline goes through meta cleavage; also, Mulla et al (2011) found that Micrococcus sp. strain SMN-1 degraded 2-nitrotoluene through 3-methylcatechol by a meta-cleavage pathway, with release of nitrite.…”

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.

“…Utilization of aromatic compounds as sole carbon sources was determined by using a minimum salt medium (Bae et al, 1996) T to use aromatic compounds in liquid medium with the same components without Noble agar. To minimize evaporation of phenolic compounds, these tests were performed in 160 ml serum bottles with butyl robber stoppers.…”

Nocardioides daeguensis sp. nov., a nitratereducing bacterium isolated from activated sludge of an industrial wastewater treatment plant A Gram-reaction-positive, rod-shaped, non-spore-forming bacterium (strain 2C1-5 T ) was isolated from activated sludge of an industrial wastewater treatment plant in Daegu, South Korea. Its taxonomic position was investigated by using a polyphasic approach. On the basis of 16S rRNA gene sequence similarity, the closest phylogenetic relatives were the type strains of Nocardioides nitrophenolicus (98.6 % similarity), N. kongjuensis (98.5 %), N. caeni (98.4 %), N. simplex (98.3 %), N. aromaticivorans (98.1 %) and N. ginsengisoli (97.5 %); the phylogenetic distance from other species with validly published names within the genus Nocardioides was greater than 3 %. Strain 2C1-5 T was characterized chemotaxonomically as having LL-2, 6-diaminopimelic acid in the cell-wall peptidoglycan, MK-8(H 4 ) as the predominant menaquinone and iso-C 16 : 0 , C 16 : 0 and C 17 : 1 v6c as the major fatty acids. The G+C content of the genomic DNA was 74.9 mol%. These chemotaxonomic properties and phenotypic characteristics supported the affiliation of strain 2C1-5 T to the genus Nocardioides. The results of physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 2C1-5 T from existing species with validly published names. Therefore, strain 2C1-5 T represents a novel species of the genus Nocardioides, for which the name Nocardioides daeguensis sp. nov. is proposed, with the type strain 2C1-5 T (5JCM 17460The genus Nocardioides was proposed by Prauser (1976) with Nocardioides albus as the type species. Since then, species affiliated with the genus Nocardioides have been actively isolated and studied taxonomically. At the time of writing, the genus comprises 57 species with validly published names, including the recently described species 3These authors contributed equally to this work.

“…Table 2 shows the effect of the phenol addition on the kinetics of PNP degradation. The rapid degradation of PNP in the presence of phenol seemed to be due to the increased cell mass rather than to the enhancement of the specific PNP degrading activity (Bae et al, 1996b). On the other hand, Schmidt et al (1987) reported that phenol had an inhibitory effect on the kinetics of PNP mineralization by Pseudomonas sp.…”

“…However, chloro-and methylaromatic compounds were simultaneously degraded via the same initial degradation pathway with the conversion to the corresponding substituted catechols (Pettigrew et al, 1991;Rojo et al, 1987;Taeger et al, 1988). Bae et al (1996b) also reported that the mixture of 4-chlorophenol and phenol was degraded via the meta-cleavage pathways of 4-chlorocatechol and catechol, respectively.…”

A p-nitrophenol (PNP)-and phenol-mineralizing bacterium (strain NSP41) was isolated from an industrial wastewater and identified as a member of the genus Nocardioides. PNP was degraded via a hydroquinone pathway, and phenol was degraded through a catechol pathway in strain NSP41. Both enzyme systems for the degradation of PNP and phenol were induced simultaneously in the presence of both compounds. Although both enzyme systems were induced at the same time, PNP and phenol were degraded by the hydroquinone and catechol pathway, respectively. However, during the simultaneous degradation in the low phenol concentration, after the exhaustion of phenol, some PNP was transformed by the catechol pathway and 4-nitrocatechol was transiently accumulated. Kinetically, the addition of phenol greatly enhanced the apparent PNP degradation rate, which may be due to the increased cell mass by the assimilation of phenol.
