pseudomonas lutea sp. nov., a novel phosphate-solubilizing bacterium isolated from the rhizosphere of grasses.a phosphate-solubilizing bacterial strain designated ok2(t) was isolated from rhizospheric soil of grasses growing spontaneously in a soil from spain. cells of the strain were gram-negative, strictly aerobic, rod-shaped and motile. phylogenetic analysis of the 16s rrna gene indicated that this bacterium belongs to the gamma-subclass of proteobacteria within the genus pseudomonas and that the closest related species is pseudomonas graminis. the strain produced catalase but not oxidase. cellulose, ...200415143034
diversity of bacteria associated with bursaphelenchus xylophilus and other nematodes isolated from pinus pinaster trees with pine wilt disease.the pinewood nematode (pwn), bursaphelenchus xylophilus, has been thought to be the only causal agent of pine wilt disease (pwd), however, since bacteria have been suggested to play a role in pwd, it is important to know the diversity of the microbial community associated to it. this study aimed to assess the microbial community associated with b. xylophilus and with other nematodes isolated from pine trees, pinus pinaster, with pwd from three different affected forest areas in portugal. one hun ...201021151611
the pseudomonas community in metal-contaminated sediments as revealed by quantitative pcr: a link with metal bioavailability.pseudomonas bacteria are ubiquitous gram-negative and aerobic microorganisms that are known to harbor metal resistance mechanisms such as efflux pumps and intracellular redox enzymes. specific pseudomonas bacteria have been quantified in some metal-contaminated environments, but the entire pseudomonas population has been poorly investigated under these conditions, and the link with metal bioavailability was not previously examined. in the present study, quantitative pcr and cell cultivation were ...201425102022
isolation and characteristics of sulfentrazone-degrading bacteria.this study aimed to isolate and characterize bacteria able to use sulfentrazone in the commercial formulation as their sole carbon source. the isolation of the potential sulfentrazone-degrading bacteria was made from soil samples with a recent history of herbicide application and from isolates identified through rdna sequencing. subsequently, we assessed the growth of the isolates and their sulfentrazone degradation ability using high-performance liquid chromatography. twenty-six potential sulfe ...201727820678
two-step statistical optimization for cold active β-glucosidase production from pseudomonas lutea bg8 and its application for improving saccharification of paddy straw.β-glucosidase is an essential part of cellulase enzyme system for efficient and complete hydrolysis of biomass. psychrotolerant pseudomonas lutea bg8 produced β-glucosidase with lower temperature optima and hence can play important role in bringing down the energy requirement for bioethanol production. to enhance β-glucosidase production, two statistical tools: taguchi and box-behnken designs were applied to reveal the most influential factors and their respective concentration for maximum produ ...201626202604
high quality draft genome sequence of the type strain of pseudomonas lutea ok2(t), a phosphate-solubilizing rhizospheric bacterium.pseudomonas lutea ok2(t) (=lmg 21974(t), cect 5822(t)) is the type strain of the species and was isolated from the rhizosphere of grass growing in spain in 2003 based on its phosphate-solubilizing capacity. in order to identify the functional significance of phosphate solubilization in pseudomonas plant growth promoting rhizobacteria, we describe here the phenotypic characteristics of strain ok2(t) along with its high-quality draft genome sequence, its annotation, and analysis. the genome is com ...201627555890
