characterization of microbial contamination in united states air force aviation fuel tanks.bacteria and fungi, isolated from united states air force (usaf) aviation fuel samples, were identified by gas chromatograph fatty acid methyl ester (gc-fame) profiling and 16s or 18s rrna gene sequencing. thirty-six samples from 11 geographically separated usaf bases were collected. at each base, an above-ground storage tank, a refueling truck, and an aircraft wing tank were sampled at the lowest sample point, or sump, to investigate microbial diversity and dispersion within the fuel distributi ...200616328508
leucobacter iarius sp. nov., in the family microbacteriaceae.a novel gram-positive bacterium, strain 40(t), was isolated in the course of identifying bacteria from infective juveniles of the entomopathogenic nematode steinernema thermophilum. based on 16s rrna gene analysis, strain 40(t) was found to be related to the type strains of recognized species of the genus leucobacter, family microbacteriaceae. the 16s rrna gene sequence similarity values of strain 40(t) and leucobacter albus iam 14851(t), leucobacter luti lmg 23118(t), leucobacter alluvii lmg 23 ...200717392186
assessment of the microbial diversity at the surface of livarot cheese using culture-dependent and independent approaches.the microbial diversity of the surface of a commercial red-smear cheese, livarot cheese, sold on the retail market was studied using culture-dependent and independent approaches. forty yeasts and 40 bacteria from the cheese surface were collected, dereplicated using single-strand conformation polymorphism (sscp) analysis and identified using rrna gene sequencing for the culture-dependent approach. the culture-independent approach involved cloning and sequencing of the 16s rrna gene and sscp anal ...200919481828
leucobacter chromiiresistens sp. nov., a chromate-resistant strain.a gram-positive, irregular rod-shaped, non-motile, yellow-pigmented bacterium, strain jg 31(t), was isolated in the course of identifying chromium-resistant soil bacteria. 16s rrna gene sequence analysis of the isolated bacterium indicated its phylogenetic position within the genus leucobacter. binary 16s rrna gene sequence alignments of the isolated bacterium with the 11 species of the genus recognized at the time of writing revealed sequence similarities of more than 97 % with leucobacter allu ...201120511468
leucobacter margaritiformis sp. nov., isolated from bamboo extract.a gram-positive aerobic rod-shaped non-motile bacterium designated a23(t) was isolated from bamboo extract that had been used to remove odor and was characterized to determine its taxonomic position. 16s rrna gene sequence analysis revealed that strain a23(t) belongs to the phylum actinobacteria. the highest degree of sequence similarities was determined to be with leucobacter salsicius m1-8(t) (96.7%), leucobacter exalbidus k-540b(t) (96.4%), leucobacter chromiireducens subsp. chromiireducens l ...201222349954
leucobacter denitrificans sp. nov., isolated from cow dung.the bacterial strain m1t8b10(t) was isolated from cow dung in suwon, republic of korea. the strain was a gram stain-positive rod, nonmotile, and non-spore-forming. according to 16s rrna gene sequence analysis, the strain fell within the clade of the genus leucobacter, showing the highest sequence similarities with leucobacter aridicollis l-9(t) (98.7%), leucobacter iarius 40(t) (98.4%), and leucobacter komagatae jcm 9414(t) (98.2%). cell-wall peptidoglycan contained the diagnostic diamino acid 2 ...201222367952
[characterization and phylogenetic analysis of the new species of the leucobacter tropicalis sp. nov].a new aerobic, gram-positive, non-sporulating, rod-shaped organism is described. strain f-8 was isolated from tropical soil, and has the following characteritics: the menaquinone contains a side chain with 11 isoprenyl units(mk-11); 2,4-diaminobutyric acid, glutamic acid, alanine, glycine and a small amount of gamma-aminobutyric acid present in the cell wall at a molar ratio of 0.77:1.0:1.66:0.95. the major cellular sugar were rhamnose, galactose and glucose. the g + c content of dna is 68 mol%. ...199912555519
comparative investigation on microbial community and electricity generation in aerobic and anaerobic enriched mfcs.this study compared the difference in microbial community and power generation capacity of air-cathode mfcs enriched under anode aerobic and anaerobic conditions. results showed that mfcs successfully started with continuous air inputting to anode chamber. the aerobic enriched mfc produced comparable and even more electricity with the fuels of acetate, glucose and ethanol compared to the anaerobic mfc when returning to anaerobic condition. the two mfcs showed a slightly different microbial commu ...201323196248
leucobacter humi sp. nov., isolated from forest soil.a novel bacterial strain, designated re6(t), was isolated from forest soil collected in campbell university, north carolina. the cells are aerobic, gram-positive, non-motile, and rod shaped. growth occurred at 4-42 °c (optimum, 25 °c), ph 6-9 (optimum, ph 6), and in 0-3 % nacl (w/v). phylogenetic analysis based on 16s rrna gene sequences indicated that strain re6(t) belonged to the genus leucobacter and showed the highest 16s rrna gene sequence similarities with leucobacter iarius jcm 14736(t) ( ...201525921298
