| leifsonia gen. nov., a genus for 2,4-diaminobutyric acid-containing actinomycetes to accommodate "corynebacterium aquaticum" leifson 1962 and clavibacter xyli subsp. cynodontis davis et al. 1984. | "corynebacterium aquaticum" was first proposed by leifson in 1962 but not included in the approved lists of bacterial names in 1980. this species has been left from reclassification of the genus corynebacterium because of the unusual chemotaxonomic characteristics such as 2,4-diaminobutyric acid (dab) in the peptidoglycan and menaquinones of mk-10 and mk-11. a close relationship of "c. aquaticum" to the genera agromyces and rathayibacter has been pointed out from the viewpoint of chemotaxonomic ... | 1999 | 12501368 |
| humibacter albus gen. nov., sp. nov., isolated from sewage sludge compost. | a bacterial strain isolated from sewage sludge compost, strain sc-083t, was characterized. the isolate was a motile, gram-positive, short rod, forming coryneform v-shaped cells during the early stages of growth. the organism was strictly aerobic and able to grow between 22 and 36 degrees c and between ph 5.5 and 8.0. the predominant fatty acids were cyclohexyl-c17 : 0, anteiso-c17 : 0 and iso-c16 : 0, the major respiratory quinones were menaquinone 11 (mk-11) and 12 (mk-12), and the genomic dna ... | 2008 | 18398211 |
| bacterial diversity of taxus rhizosphere: culture-independent and culture-dependent approaches. | the regional variability of taxus rhizosphere bacterial community composition and diversity was studied by comparative analysis of three large 16s rrna gene clone libraries from the taxus rhizosphere in different regions of china (subtropical and temperate regions). one hundred and forty-six clones were screened for three libraries. phylogenetic analysis of 16s rrna gene sequences demonstrated that the abundance of sequences affiliated with gammaproteobacteria, betaproteobacteria, and actinobact ... | 2008 | 18576948 |
| [purification and characterization of a beta-d-xylosidase from leifsonia shinshuensis dicp 16]. | a beta-d-xylosidase from leifsonia shinshuensis dicp 16 was purified to apparent homogeneity using a combination of ammonium sulfate precipitation, de 52 anion-exchange, q-sepharose fast flow anion-exchange, toyopearl butyl 650c hydrophobic-interaction and sephacryl s-300 hr gel-permeation chromatography. the purified xylosidase consisted of two same subunits and had the relative molecular weight of 180 kd as determined by sds-page and gel-permeation chromatography. the maximal beta-d-xylosidase ... | 2008 | 18724710 |
| leifsonia kribbensis sp. nov., isolated from soil. | a yellow-pigmented actinobacterium, designated strain msl-13t, was isolated from a soil sample collected from bigeum island, republic of korea, and its taxonomic position was determined by using a polyphasic approach. strain msl-13t showed phenotypic and chemotaxonomic properties consistent with its classification in the genus leifsonia. 16s rrna gene sequence analysis of strain msl-13t with sequences from leifsonia naganoensis db103t, leifsonia aquatica dsm 20146t, leifsonia xyli subsp. cynodon ... | 2009 | 19126716 |
| leifsonia soli sp. nov., a yellow-pigmented actinobacterium isolated from teak rhizosphere soil. | two yellow-pigmented, gram-stain-positive, aerobic, motile, short rod-shaped bacteria were isolated from natural teak tree rhizosphere soil and their taxonomic positions were determined by using a polyphasic approach. comparative 16s rrna gene sequence analysis showed that strains tg-s248(t) and tg-s240 formed a distinct phyletic line within the genus leifsonia. 16s rrna gene sequence analysis of strain tg-s248(t) with sequences from leifsonia shinshuensis db 102(t), l. poae vkm ac-1401(t), l. n ... | 2010 | 19667370 |
| rational design of a plasmid origin that replicates efficiently in both gram-positive and gram-negative bacteria. | most plasmids replicate only within a particular genus or family. | 2010 | 20949038 |
| identification and characterization of endophytic bacteria isolated from in vitro cultures of peach and pear rootstocks. | endophytes are microorganisms which live symbiotically with almost all varieties of plant and in turn helping the plant in a number of ways. instead of satisfactory surface sterilization approaches, repeatedly occurring bacterial growth on in vitro rootstock cultures of peach and pear was identified and isolated as endophytic bacteria in our present study. five different isolates from peach rootstocks were molecularly identified by 16s rrna gene sequencing as brevundimonas diminuta, leifsonia sh ... | 2016 | 28330195 |
