delftia lacustris sp. nov., a peptidoglycan-degrading bacterium from fresh water, and emended description of delftia tsuruhatensis as a peptidoglycan-degrading bacterium.extracellular peptidoglycan is commonly found in natural environments, yet little is known about its biodegradation in nature. we here describe a novel peptidoglycan-degrading bacterium, designated strain 332t, isolated from mesotrophic lake water in denmark. the strain was a gram-negative-staining, motile rod. it had chitinase and lysozyme activities, which are relevant to peptidoglycan degradation, and was capable of utilizing several mono- and disaccharides, amino acids and organic acids. phy ...200919605727
diversity analysis of diazotrophic bacteria associated with the roots of tea (camellia sinensis (l.) o. kuntze).the diversity elucidation by amplified ribosomal dna restriction analysis and 16s rdna sequencing of 96 associative diazotrophs, isolated from the feeder roots of tea on enriched nitrogen-free semisolid media, revealed the predominance of gram-positive over gram-negative bacteria within the kangra valley in himachal pradesh, india. the gram-positive bacteria observed belong to two taxonomic groupings; firmicutes, including the genera bacillus and paenibacillus; and actinobacteria, represented by ...201121715960
delftia litopenaei sp. nov., a poly-β-hydroxybutyrate-accumulating bacterium isolated from a freshwater shrimp culture pond.a gram-negative, short-rod-shaped, motile, non-spore-forming and poly-β-hydroxybutyrate-accumulating bacterial strain, designated wsw-7t, was isolated from a freshwater shrimp culture pond in taiwan and was characterized using the polyphasic taxonomy approach. phylogenetic analyses based on 16s rrna gene sequences showed that the closest relatives of strain wsw-7t were delftia lacustris 332t, delftia tsuruhatensis t7t and delftia acidovorans atcc 15668t, with sequence similarities of 98.5, 98.4 ...201122140156
control of wilt and rot pathogens of tomato by antagonistic pink pigmented facultative methylotrophic delftia lacustris and bacillus spp.the studies on the biocontrol potential of pink pigmented facultative methylotrophic (ppfm) bacteria other than the genus methylobacterium are scarce. in the present study, we report three facultative methylotrophic isolates; ppo-1, ppt-1, and ppb-1, respectively, identified as delftia lacustris, bacillus subtilis, and bacillus cereus by 16s rrna gene sequence analysis. hemolytic activity was tested to investigate the potential pathogenicity of isolates to plants and humans, the results indicate ...201627872630
delftia deserti sp. nov., isolated from a desert soil sample.a gram-staining negative, short rod, motile, light brownish-pigmented bacterial strain, designated yim y792(t), was isolated from a soil sample taken from turpan desert in xinjiang uyghur autonomous region, north-western china. phylogenetic analysis indicated that strain yim y792(t) belongs to the genus delftia. strain yim y792(t) shared highest 16s rrna gene sequence similarities with delftia lacustris dsm 21246(t) (93.96 %), delftia tsuruhatensis nbrc 16741(t) (93.74 %), and delftia acidovoran ...201525842037
genome sequencing reveals mechanisms for heavy metal resistance and polycyclic aromatic hydrocarbon degradation in delftia lacustris strain lz-c.strain lz-c, isolated from a petrochemical wastewater discharge site, was found to be resistant to heavy metals and to degrade various aromatic compounds, including naphenol, naphthalene, 2-methylnaphthalene and toluene. data obtained from 16s rrna gene sequencing showed that this strain was closely related to delftia lacustris. the 5,889,360 bp genome of strain lz-c was assembled into 239 contigs and 197 scaffolds containing 5855 predicted open reading frames (orfs). among these predicted orfs, ...201626589947
ocular infection associated with delftia lacustris: first report. 201526095905
delftia lacustris septicemia in a pheochromocytoma patient: case report and literature review.we report the first case of true delftia lacustris bacteremia in a patient with pheochromocytoma. the organism was identified using 16s rrna gene sequencing and biochemical tests. a peripheral intravenous catheter was the suspected source of infection, and the patient was successfully treated with piperacillin/tazobactam. we also present a review of the literature describing bacteremia caused by delftia species.201525712727
four cases of possible human infections with delftia lacustris.we report four cases of possible human infections with delftia lacustris. d. lacustris isolates, which were isolated from blood cultures and bile fluid of patients with underlying diseases such as empyema, renal injury, hepatocellular carcinoma, and renal infarction, were identified using 16s rrna gene sequencing and biochemical tests. four d. lacustris isolates did not show the same antimicrobial susceptibility profiles and enterobacterial repetitive intergenic consensus-polymerase chain reacti ...201223055149
