phylogenetic analysis of the coryneform bacteria by 5s rrna sequences.	nucleotide sequences of 5s rrnas from 11 coryneform bacteria were determined. these were the type strains of corynebacterium glutamicum, corynebacterium xerosis, brevibacterium linens, arthrobacter globiformis, cellulomonas biazotea, aureobacterium testaceum, curtobacterium citreum, pimelobacter simplex, and caseobacter polymorphus and representative strains of "corynebacterium aquaticum" and corynebacterium xerosis. a phylogenetic tree constructed from the sequences of these bacteria and publis ...	1987	3106318
cloning and sequencing of trehalose synthase gene from pimelobacter sp. r48.	the gene encoding trehalose synthase (catalyzing the conversion of maltose into alpha, alpha-trehalose by intramolecular transglucosylation) was cloned from pimelobacter sp. r48. sequence analysis revealed a 1719-bp synthase gene and a 573-residue amino-acid sequence. the 220 n-terminal residues were homologous to those of maltases from saccharomyces carlsbergensis and aedes aegypti.	1996	8645698
purification and properties of a novel enzyme, trehalose synthase, from pimelobacter sp. r48.	a novel enzyme, trehalose synthase, was purified from a cell-free extract of pimelobacter sp. r48 to an electrophoretically homogeneous state by successive chromatographies on deae-toyopearl 650, butyl-toyopearl 650, and mono q hr5/5 columns. the molecular weight of the enzyme was estimated to be 62,000 by sds-polyacrylamide gel electrophoresis, and the enzyme had a pi of 4.6 by gel isoelectrofocusing. the enzyme catalyzed the conversion of maltose into trehalose by intramolecular transglucosyla ...	1996	8829531
influence of a supplementary carbon source on biodegradation of pyridine by freely suspended and immobilized pimelobacter sp..	the effect of the presence of supplementary glucose or acetate on the growth and pyridine-degrading activity of freely suspended and calcium-alginate-immobilized pimelobacter sp. was investigated. although the supplementary carbon sources could be degraded simultaneously with pyridine, pimelobacter sp. exhibited a preference for pyridine over supplementary carbon sources. thus, the pyridine-degrading activity of the freely suspended cells was not decreased significantly by the addition of either ...	1996	8867640
the application of serological techniques to the taxonomy of arthrobacter and related organisms.	antisera were raised against rods of 17 named arthrobacter and aureobacterium strains. antigenic relationships between these strains, other soil bacteria and new arthrobacter isolates from several soils were studied, using agglutination, immunodiffusion, immunofluorescence and elisa techniques. many of the named arthrobacter species had common antigens, and there were also common antigens amongst named arthrobacter strains and many fresh arthrobacter isolates. agglutination, elisa and immunofluo ...	1996	8868431
cloning and sequencing of trehalose synthase gene from thermus aquaticus atcc33923.	the gene encoding trehalose synthase (catalyzing the conversion of maltose into alpha, alpha-trehalose by transglucosylation) was cloned from thermus aquaticus atcc33923. sequence analysis revealed a 2892 bp synthase gene and a 963 residue amino-acid sequence. the 547 n-terminal residues were homologous to the full-length synthase from pimelobacter sp. r48 (53.8% identity).	1997	9042362
cloning and characterization of the gene for amylosucrase from neisseria polysaccharea: production of a linear alpha-1,4-glucan.	the gene for the amylosucrase from neisseria polysaccharea (atcc 43768) was cloned by use of a functional expression system in escherichia coli xl1-blue. the deduced amino acid sequence of the protein has homology to the sequences of the alpha-amylase class of enzymes, with the highest similarities being found to the sequences of the trehalose synthase from pimelobacter sp. strain r48 (17) and amylomaltase from thermotoga maritima (11). however, the regions of highest homology within the alpha-a ...	1997	9150231
nocardioides pyridinolyticus sp. nov., a pyridine-degrading bacterium isolated from the oxic zone of an oil shale column.	a bacterial strain which is able to degrade pyridine was previously isolated from the oxic zone of an oil shale column and described as pimelobacter sp. strain os4t. however, pimelobacter species have been transferred to the genera nocardioides and terrabacter. strain os4t was identified as a member of the genus nocardioides on the basis of chemotaxonomic analysis and phylogenetic inference based on 16s ribosomal dna (rdna) sequence analysis. the g+c content of strain os4t is 72.5 mol%. the cell ...	1997	9336889
[conversion of 17 alpha-methyltestosterone to methandrostenolone by the bacterium pimelobacter simplex vkpm ac-1632 with the presence of cyclodextrins].	conditions of conversion of 17 alpha-methyltestosterone to methandrostenolone with the presence of modified beta-cyclodextrins (methylcyclodextrin, hydroxypropylcyclodextrin, and hydroxyethylcyclodextrin) in the steroid:cyclodextrin ratio 1:1 were studied. the experimental solutions of modified beta-cyclodextrins were prepared in deionized water with 5-7% methanol. under the conditions found to be optimal, 1,2-dehydrogenation of 17 alpha-methyltestosterone was carried out with 2-4 g/l pimelobact ...	2008	19145970
biodegradation of 17alpha-methyltestosterone and isolation of mt-degrading bacterium from sediment of nile tilapia masculinization pond.	the fast growing and highly tolerant fish nile tilapia is one of the most commonly raised fish in the aquaculture industry. to produce an all-male population, a common practice is to feed the nile tilapia fry with 17alpha-methyltestosterone (mt)-impregnated food. uneaten fish food with mt may accumulate in the masculinization ponds and be released into the receiving waters. not much is known about the fate of mt in the fish farms and in the receiving streams. the objective of this study is to in ...	2009	19182335
[conversion of soybean sterols into 3,17-diketosteroids using actinobacteria mycobacterium neoaurum, pimelobacter simplex, and rhodococcus erythropolis].	abstract-soybean sterols were converted into androst-4-ene-3,17-dione (ad) and 9alpha-hydroxyandrost-4-ene-3,17-dione (9-oh-ad) using three actinobacterium strains. the transformation of a microcrystallic substrate (particle size 5-15 nm) or the transformation in the presence of randomly methylated beta-cyclodextrin (mcd) were carried out by mycobacterium neoaurum with a phytosterol load of 30 g/l over 144 h with an ad content of 14.5 and 15.2 g/l, respectively. ad obtained in the presence of mc ...	2011	21790029
