| numerical analysis of relationships among rapidly growing, scotochromogenic mycobacteria. | numerical analysis of the relationships among rapidly growing, scotochromogenic mycobacteria was carried out; a dendrogram was prepared by a single linkage method and the separation between species was tested. the following were distinct species: mycobacterium alichiense; mycobacterium rhodesiae;mycobacterium chubuense; mycobacterium obuense; mycobacterium gilvum; mycobacterium duvalii; mycobacterium flavescens; and mycobacterium vaccae. mycobacterium tokaiense was reduced to a synonym of m. chu ... | 1977 | 853289 |
| mycolic acid patterns of some rapidly-growing species of mycobacterium. | representative strains of some rapidly-growing species of mycobacterium were degraded by both acid methanolysis and alkaline hydrolysis followed by phase-transfer catalysed conversion to methyl esters. patterns of mycolic acids and other long-chain components were determined for 56 samples by two-dimensional thin-layer chromatography. representatives of mycobacterium chitae contained epoxymycolates and alpha and alpha'-mycolates, lacking oxygen functions in addition to the 3-hydroxyacid unit; a ... | 1985 | 4050199 |
| phylogenetic evidence for transfer of pentachlorophenol-mineralizing rhodococcus chlorophenolicus pcp-i(t) to the genus mycobacterium. | we determined the nucleotide sequence of a 16s rrna gene of rhodococcus chlorophenolicus pcp-i(t) (= dsm 43826t) (t = type strain). sequence comparisons revealed that there was a close relationship between strain pcp-i(t) and strains belonging to the genus mycobacterium. the sequence data were used to construct a phylogenetic tree, which showed that mycobacterium chubuense is the closest relative of strain pcp-i(t). we propose that strain pcp-i(t) should be transferred to the genus mycobacterium ... | 1994 | 7520738 |
| isolation and identification of mycobacteria from soils at an illegal dumping site and landfills in japan. | in order to study the diversity and community of genus mycobacterium in polluted soils, we tried to isolate mycobacteria from 11 soil samples collected from an illegal dumping site and 3 landfills in japan. using culture methods with or without acanthamoeba culbertsoni, a total of 19 isolates of mycobacteria were obtained from 5 soil samples and 3 of them were isolated only by the co-culture method with the amoeba. conventional biochemical tests and sequencing of the hsp65, rpob, and 16s rrna ge ... | 2006 | 16858142 |
| surface spreading motility shown by a group of phylogenetically related, rapidly growing pigmented mycobacteria suggests that motility is a common property of mycobacterial species but is restricted to smooth colonies. | motility in mycobacteria was described for the first time in 1999. it was reported that mycobacterium smegmatis and mycobacterium avium could spread on the surface of solid growth medium by a sliding mechanism and that the presence of cell wall glycopeptidolipids was essential for motility. we recently reported that mycobacterium vaccae can also spread on growth medium surfaces; however, only smooth colonies presented this property. smooth colonies of m. vaccae do not produce glycopeptidolipids ... | 2008 | 18689490 |
| biodegradation of vinyl chloride, cis-dichloroethene and 1,2-dichloroethane in the alkene/alkane-oxidising mycobacterium strain nbb4. | mycobacterium chubuense strain nbb4 can grow on both alkanes and alkenes as carbon sources, and was hypothesised to be an effective bioremediation agent for chlorinated aliphatic pollutants. in this study, the ability of nbb4 to biodegrade vinyl chloride (vc), cis-dichloroethene (cdce) and 1,2-dichloroethane (dca) was investigated under pure-culture conditions and in microcosms. ethene-grown nbb4 cells were capable of biodegrading vc and cdce, while ethane-grown cells could biodegrade cdce and d ... | 2011 | 21365473 |
| characterization of three mycobacterium spp. with potential use in bioremediation by genome sequencing and comparative genomics. | we provide the genome sequences of the type strains of the polychlorophenol-degrading mycobacterium chlorophenolicum (dsm43826), the degrader of chlorinated aliphatics mycobacterium chubuense (dsm44219) and mycobacterium obuense (dsm44075) that has been tested for use in cancer immunotherapy. the genome sizes of m. chlorophenolicum, m. chubuense, and m. obuense are 6.93, 5.95, and 5.58 mb with gc-contents of 68.4%, 69.2%, and 67.9%, respectively. comparative genomic analysis revealed that 3,254 ... | 2015 | 26079817 |

| untangling the multiple monooxygenases of mycobacterium chubuense strain nbb4, a versatile hydrocarbon degrader. | mycobacterium strain nbb4 was isolated on ethene as part of a bioprospecting study searching for novel monooxygenase (mo) enzymes of interest to biocatalysis and bioremediation. previous work indicated that strain nbb4 contained an unprecedented diversity of mo genes, and we hypothesized that each mo type would support growth on a distinct hydrocarbon substrate. here, we attempted to untangle the relationships between mo types and hydrocarbon substrates. strain nbb4 was shown to grow on c2 -c4 a ... | 2011 | 23761275 |
| mycobacteria are hidden endophytes in the shoots of rock plant [pogonatherum paniceum (lam.) hack.] (poaceae). | a mycobacterium was isolated from micropropagated pogonatherum paniceum and identified as a close relative of mycobacterium cookii. the endophyte diversity in the shoots of potted and micropropagated p. paniceum plants was studied by culture-independent techniques. group- and strain-specific pcr demonstrated that the p. paniceum plants harboured the isolated mycobacterium strain as a minority. altogether 101 clones of the pcr products were sequenced. the shoots of potted p. paniceum plants harbo ... | 2010 | 23766233 |
