“…It can utilize a wide variety of organic compounds such as aromatic hydrocarbons, nucleic acids and their degradation products, herbicide, etc. Therefore, Athrobacter species were thought to play a significant role in the biodegradation of organic matter (Cacciari and Lippi 1987;Crocker et al 2000;Jones and Keddie 2006;Niewerth et al 2012). However, Arthrobacter have been rarely reported as cellulose-degrading bacteria (Jones and Keddie 2006;Soares et al 2012).…”

“…The low minimum growth rate, the accumulation of a large amount of reserve material, the rapid and drastic decrease in endogenous metabolism and the long survival times during starvation, the high resistance to desiccation in soil and the small spheroidal shape of cells under conditions of nutrient depletion might be the basis for the ecological prominence of Arthrobacter in arid soils (Cacciari and Lippi 1986). Chen and Alexander (1973) studied survival of Arthrobacter as a function of a w and found that the minimum a w for growth was 0.940.…”

Identification of large linear plasmids in Arthrobacter spp. encoding the degradation of quinaldine to anthranilate

Arthrobacter nitroguajacolicus Rü 61a, which utilizes quinaldine as sole source of carbon and energy, was shown to contain a conjugative linear plasmid of approximately 110 kb, named pAL1. It exhibits similarities with other linear plasmids from Actinomycetales in that it has proteins covalently attached to its 59 ends. Southern hybridization with probes for the genes encoding quinaldine 4-oxidase and N-acetylanthranilate amidase indicated that pAL1 contains the gene cluster encoding the degradation of quinaldine to anthranilate. A mutant of strain Rü 61a that had lost pAL1 indeed could not convert quinaldine, but was still able to grow on anthranilate. Conjugative transfer of pAL1 to the plasmid-less mutant of strain Rü 61a and to Arthrobacter nicotinovorans DSM 420 (pAO1) occurred at frequencies of 5?4610 "4 and 2?0610per recipient, respectively, and conferred the ability to utilize quinaldine. Five other quinaldine-degrading Gram-positive strains were isolated from soil samples; 16S rDNA sequence analysis suggested the closest relationship to different Arthrobacter species. Except for strain K2-29, all isolates contained a pAL1-like linear plasmid carrying genes encoding quinaldine conversion. A 478 bp fragment that on pAL1 represents an intergenic region showed 100 % sequence identity in all isolates harbouring a pAL1-like plasmid, suggesting horizontal dissemination of the linear plasmid among the genus Arthrobacter. INTRODUCTIONBacteria of the genus Arthrobacter are considered to be ubiquitous in soil and have been found to be among the predominant members of culturable communities from several terrestrial subsurface environments (Crocker et al., 2000). Among the explanations advanced for their ubiquity or even predominance in soil are their resistance to desiccation and nutrient depletion, and their nutritional versatility. Arthrobacter spp. utilize a wide and varied range of natural as well as xenobiotic compounds and thus may play a significant role in the mineralization of organic matter in the environment (Cacciari & Lippi, 1987).Arthrobacter nitroguajacolicus strain Rü61a (formerly assigned to the species Arthrobacter ilicis) utilizes quinaldine (2-methylquinoline), a constituent of coal tar, as sole source of carbon and energy (Hund et al., 1990). Degradation via the anthranilate pathway ( Fig. 1) is initiated by the oxidation of quinaldine to 1H-4-oxoquinaldine, catalysed by quinaldine 4-oxidase (Qox). 1H-4-oxoquinaldine 3-monooxygenase subsequently generates 1H-3-hydroxy-4-oxoquinaldine, which undergoes 2,4-dioxygenolytic ring cleavage to form carbon monoxide and N-acetylanthranilate. This unusual mode of ring cleavage is catalysed by a cofactor-less 2,4-dioxygenase that does not share any similarity with aromatic ring cleavage dioxygenases, but seems to belong to the a/b-hydrolase fold superfamily of proteins (Fetzner, 2002). In the next step, an amidase (Amq) catalyses the hydrolysis of N-acetylanthranilate to anthranilate. We have characterized the gene cluster encoding this 'upper part' of th...
