| chryseobacterium soli sp. nov. and chryseobacterium jejuense sp. nov., isolated from soil samples from jeju, korea. | two yellow-pigmented bacterial strains, js6-6(t) and js17-8(t), isolated from soil samples from jeju, republic of korea, were studied to determine their taxonomic positions. the cells of the two bacteria were aerobic, gram-negative, non-motile, straight rods. 16s rrna gene sequence analysis indicated that both isolates should be placed in the genus chryseobacterium of the family flavobacteriaceae. their 16s rrna gene sequences showed similarities of 93.7-97.5 % to those of type strains of the ge ... | 2008 | 18218951 |
| chryseobacterium piscicola sp. nov., isolated from diseased salmonid fish. | eight bacterial strains isolated from diseased rainbow trout (n=5) and atlantic salmon (n=3) were characterized by phenotypic and molecular taxonomic methods. the isolates were negative for the gram-reaction, non-motile, rod-shaped and catalase- and oxidase-positive. colonies on solid media were yellow, smooth, shiny and circular with regular edges. growth occurred at 4-28 degrees c (optimum, 15 degrees c) and with 0-3 % nacl (optimum, 0.5 %). analysis of the 16s rrna gene sequence allocated the ... | 2009 | 19643904 |
| novel ultramicrobacterial isolates from a deep greenland ice core represent a proposed new species, chryseobacterium greenlandense sp. nov. | three novel orange, ultramicrobacterial isolates, umb10, umb14, and umb34(t) were isolated from enrichment cultures inoculated with a melted 3,043 m deep greenland ice core sample. phylogenetic analysis of the 16s rrna gene sequences indicated that the isolates belonged to a single species within the genus chryseobacterium. they were most closely related to chryseobacterium aquaticum (99.3%), chryseobacterium soli (97.1%), and chryseobacterium soldanellicola (96.9%). genomic hybridization showed ... | 2010 | 19888547 |
| chryseobacterium ginsenosidimutans sp. nov., a bacterium with ginsenoside-converting activity isolated from soil of a rhus vernicifera-cultivated field. | a gram-reaction-negative, strictly aerobic, non-motile, non-spore-forming, rod-shaped bacterial strain, designated thg 15(t), was isolated from soil of a field cultivated with rhus vernicifera in okcheon province, south korea, and its taxonomic position was investigated by using a polyphasic approach. strain thg 15(t) grew optimally at 25-30 °c and at ph 7 in the absence of nacl on nutrient agar. strain thg 15(t) displayed β-glucosidase (aesculinase) activity that was responsible for its ability ... | 2010 | 20656821 |
| chryseobacterium piperi sp. nov., isolated from a freshwater creek. | as part of an undergraduate microbiology course, a yellow-orange pigmented, gram-staining negative, rod-shaped, non-motile bacterial strain was isolated from a north-central pennsylvania creek during winter. the sequence of the 16s rrna gene of this strain, designated ctmt, was approximately 97% similar to those of chryseobacterium soldanellicola and chryseobacterium soli, while the protein-coding gyrb gene was less than 87% similar to those of these closest relatives. polyphasic characterizatio ... | 2010 | 20889766 |
| systematic functional analysis and application of a cold-active serine protease from a novel chryseobacterium sp. | psychrotolerant bacteria isolated from natural and artificially cold environments were screened for synthesis of cold-active protease. the strain imdy showing the highest protease production at 5°c was selected and phylogenetic analysis revealed that imdy as novel bacterium with chryseobacterium soli(t) as its nearest neighbor. classical optimization enhanced the protease production from 18u/mg to 26u/mg and the enzyme was found to be active at low temperature, activity enhanced by cacl2, inhibi ... | 2017 | 27664603 |
