| silvimonas terrae gen. nov., sp. nov., a novel chitin-degrading facultative anaerobe belonging to the 'betaproteobacteria'. | a taxonomic study was carried out on a bacterial strain, designated km-45t, isolated from forest soil collected near daejeon, south korea. comparative 16s rrna gene sequence analysis indicated a clear affiliation of this bacterium to the 'betaproteobacteria' and that it was related most closely to chitinibacter tainanensis bcrc 17254t, formivibrio citricus dsm 6150t and iodobacter fluviatilis atcc 33051t (92.4, 91.2 and 88.9 % 16s rrna gene sequence similarity, respectively). cells were gram-neg ... | 2005 | 16280491 |
| deefgea rivuli gen. nov., sp. nov., a member of the class betaproteobacteria. | two strains, designated wb 3.4-79(t) and wb 3.3-25, were isolated from a hard-water sample collected from the westerhöfer bach, lower saxony, germany. the strains shared 100 % dna-dna relatedness, indicating membership of the same genospecies. this close relationship was supported by identical 16s rrna gene sequences and high similarities in fatty acid composition and biochemical characteristics. the g+c content of the genomic dna of strain wb 3.4-79(t) was 48.5 mol% and the predominant ubiquino ... | 2007 | 17329799 |
| andreprevotia chitinilytica gen. nov., sp. nov., isolated from forest soil from halla mountain, jeju island, korea. | a motile, gram-negative, rod-shaped bacterium, designated strain js11-7(t), was isolated from forest soil from halla mountain, jeju island, korea. it grew optimally at 28 degrees c, ph 6-7 and in the presence of 0-2 % (w/v) nacl. phylogenetic analyses based on 16s rrna gene sequences showed that strain js11-7(t) belongs to the family neisseriaceae, with silvimonas terrae as its closest relative (95.0 % similarity). it contained q-8 as the predominant quinone and summed feature 3 (comprising iso- ... | 2007 | 17625196 |
| chitinilyticum aquatile gen. nov., sp. nov., a chitinolytic bacterium isolated from a freshwater pond used for pacific white shrimp culture. | strain c14(t), originally isolated from surface water of a freshwater pond located in pingtung (southern taiwan) used for culture of pacific white shrimp (litopenaeus vannamei), was subjected to a polyphasic taxonomic approach. the strain exhibited strong chitinolytic activity and was able to grow under aerobic and anaerobic conditions by utilizing chitin exclusively as the carbon, nitrogen and energy source. phylogenetic analysis of the 16s rrna gene sequence revealed a clear affiliation of the ... | 2007 | 18048738 |
| silvimonas iriomotensis sp. nov. and silvimonas amylolytica sp. nov., new members of the class betaproteobacteria isolated from the subtropical zone in japan. | the taxonomic positions of two bacterial strains, ir6-1(t) and ir6-4(t), isolated from soil collected in iriomote island in japan, were determined by using a polyphasic taxonomic approach. the strains were facultatively anaerobic, motile and gram-stain-negative rods and their optimum ph for growth was ph 4.0. their major respiratory quinone was ubiquinone-8 and the predominant cellular fatty acids were c(14 : 0), c(16 : 0), c(16 : 1)omega7c and c(18 : 1)omega7c. the g+c content of the genomic dn ... | 2010 | 19648333 |
| jeongeupia naejangsanensis gen. nov., sp. nov., a cellulose-degrading bacterium isolated from forest soil from naejang mountain in korea. | a gram-stain-negative, motile, rod-shaped, cellulose-degrading bacterial strain, bio-tas4-2(t), which belongs to the betaproteobacteria , was isolated from forest soil from naejang mountain, korea, and its taxonomic position was investigated by using a polyphasic study. strain bio-tas4-2(t) grew optimally at ph 7.0-8.0, at 30 degrees c and in the presence of 0-1.0 % (w/v) nacl. phylogenetic trees based on 16s rrna gene sequences showed that strain bio-tas4-2(t) clustered with members of the gene ... | 2010 | 19654346 |
| [effects of microbial agent inoculation on bacterial community diversity in the process of pig manure composting]. | pcr-dgge method was adopted to study the effects of inoculating exogenous microbial agent on the bacterial community diversity in the process of fresh pig manure high-temperature aerobic composting. exogenous microbial agent inoculation promoted the composting process, with the high-temperature period being advanced by 2 days than that of non-inoculation. dgge pattern analysis showed that during composting, the dominant bacteria changed significantly, with the shannon-wiener index of bacterial c ... | 2009 | 19947226 |
| chitinivorax tropicus gen. nov., sp. nov., a chitinolytic bacterium isolated from a freshwater lake. | a faculatively anaerobic, chitinolytic bacterium, strain kl-9t, was isolated from freshwater lake in taiwan and was characterized using the polyphasic taxonomy approach. the cells were gram-negative, rod-shaped, motile by means of a polar single flagellum and non-spore forming. growth occurred at 15-40 -¦c (optimum, 30-37-¦c), at ph 7.0-9.0 (optimum, ph 8.0) and with 0-1.0 % nacl (optimum, 0 %). the predominant fatty acids were summed feature 3 (comprising c16:1¤ë7c and/or c16:1¤ë6c) and c16:0. ... | 2011 | 21705448 |
