| arthrobacter rhombi sp. nov., isolated from greenland halibut (reinhardtius hippoglossoides). | two strains of a hitherto undescribed gram-positive coryneform bacterium isolated from greenland halibut (reinhardtius hippoglossoides) were characterized by phenotypic and molecular taxonomic methods. comparative 16s rrna gene sequencing studies demonstrated that the unknown strains constitute a new line within the genus arthrobacter. the nearest relatives of the bacterium from fish were members of the arthrobacter nicotianael arthrobacter sulfureus group. the unknown bacterium was readily dist ... | 1999 | 10425782 |
| transformation of 2-aminoacetophenone to ( s) -2-amino-1-phenylethanol by arthrobacter sulfureus. | a new isolate of arthrobacter sulfureus , when incubated at 50 g resting cells (dry cell wt) l(-1) with 50 g glucose l(-1) and 1 g 2-aminoacetophenone l(-1) in 50 mm potassium buffer (ph 7, 4 ml) at 30 degrees c, produced ( s )-2-amino-1-phenylethanol (e.e. >99%) with 75% yield in 6 h. | 2004 | 15483382 |
| arthrobacter psychrophenolicus sp. nov., isolated from an alpine ice cave. | on the basis of phenotypic, genotypic and chemotaxonomic characteristics, a novel species belonging to the genus arthrobacter is described. a facultatively psychrophilic bacterium, strain ag31(t), was isolated from an alpine ice cave. the aerobic, gram-positive, non-spore-forming, non-motile strain exhibited a rod-coccus growth cycle and produced a yellow pigment. good growth and phenol biodegradation occurred at a temperature range of 1-25 degrees c. up to 10 mm phenol was utilized as a sole ca ... | 2004 | 15545436 |
| arthrobacter gangotriensis sp. nov. and arthrobacter kerguelensis sp. nov. from antarctica. | two coryneform bacteria were isolated from a penguin rookery soil sample collected in antarctica, near the indian station dakshin gangotri (strain lz1y(t)), and from sea water from kerguelen island, antarctica (strain kgn15(t)). they have morphological and chemotaxonomic properties (peptidoglycan a4alpha type; major menaquinones mk-8, mk-9 and mk-10; predominant fatty acids anteiso-c(15 : 0) and anteiso-c(17 : 0)) that are characteristic of members of the genus arthrobacter. the isolates shared ... | 2004 | 15545486 |
| desulphurization of dibenzothiophene and diesel oils by bacteria. | to study the desulphurization of dibenzothiophene (dbt), a recalcitrant thiophenic component of fossil fuels, by two bacteria namely rhodococcus sp. and arthrobacter sulfureus isolated from oil-contaminated soil/sludge in order to use them for reducing the sulphur content of diesel oil in compliance with environmental regulations. | 2005 | 15715638 |
| environmental parameters conditioning microbially induced mineralization under the experimental model conditions. | microbially induced calcium carbonate precipitation is one of the biomineralization types closely dependent on the parameters of the microenvironment. minerals are precipitated as a product of environmental and bacterial cell interactions, however, this system has very little control via microorganisms. the aim of research was to determine the influence of abiotic factors (ph, temperature, agitation speed of bacterial culture and calcium ion source) on the mineralization induced by arthrobacter ... | 2016 | 26894236 |
| taxonomic studies on arthrobacter nicotianae and related taxa: description of arthrobacter uratoxydans sp. nov. and arthrobacter sulfureus sp. nov. and reclassification of brevibacterium protophormiae as arthrobacter protophormiae comb. nov. | dna homology studies were performed on various strains of arthrobacter and related organisms with peptidoglycans (mureins) of the a3α and a4α variations. homology values above 20% show strains with the a4α variation to form a coherent group, which is here designated as the "nicotianae" group of organisms. members of this group show homology values of lower than 20% with strains of the "globiformis" group (arthrobacter globiformis and relatives), having a a3α peptidoglycan variation. however, the ... | 1983 | 23194805 |
| purification and characterization of a novel nadph-dependent 2-aminoacetophenone reductase from arthrobacter sulfureus. | a novel 2-aminoacetophenone reductase was purified to homogeneity from arthrobacter sulfureus bw1010. the enzyme is a monomer with a molecular weight of approximately 60 kda. using nadph as coenzyme, it catalyzes the reduction of ketones, especially amine phenyl ketones, and stereospecifically reduces 2-aminoacetophenone to (s)-2-amino-1-phenylethanol (e.e > 99.8%) with the optimal ph at 7.5. | 2015 | 25488497 |
