The antibacterial activity of Bulbophyllum neilgherrense was tested against five species of bacteria, viz., Escherichia coli, Staphylococcus aureus, Bacillus pumilus, Pseudomonas aeruginosa and Pseudomonas putida Aqueous, ethanolic and chloroform soluble extracts of leaf and pseudobulb (5.50 w/v) were screened for their antibacterial potential. The zone of inhibition was seen to be largest when...
A DNA fragment of 485 bp was specifically amplified by PCR with primers based on the N-terminal sequence of the purified formaldehyde dehydrogenase (EC 1.2.1.46) from Pseudomonas putida and on that of a cyanogen bromide-derived peptide. With this product as a probe, a gene coding for formaldehyde dehydrogenase (fdhA) in P. putida chromosomal DNA was cloned in Escherichia coli DH5ot. Sequencing ...
Incubation of racemic mixtures of dl-(+/-)-nicotine with Pseudomonas putida resulted in a complete stereoselective degradation of the l-(-) isomer. Unnatural d-(+)-nicotine, which is of pharmacological interest for stereochemical studies of various nicotine-responsive systems, was not affected by the bacterium and was recovered by extraction.
The transfer of transducing phage DNA in association with the mandelate genetic region of Pseudomonas putida strain PRS1 (termed pfdm) has been achieved by growing together mandelate-positive PpG2 cells harboring pfdm as an extrachromosomal element and mandelate-deleted PpG1 strains. This transfer is analogous to sexual conjugation in the enterobacteria. The transfer of pfdm elements is always ...
In this study, we report the draft genome ofPseudomonas putidaBW11M1, a banana rhizosphere isolate producing various antimicrobial compounds, including a lectin-like bacteriocin, an R-type tailocin, the cyclic lipopeptide xantholysin, and the fatty acid-derived pseudopyronine.
The chemotactic response of wild-type Pseudomonas putida and P. tolaasii, and a phenotypic variant of each species, to Agaricus bisporus mycelial exudate was examined. Both P. putida, the bacterium responsible for initiating basidiome development of A. bisporus, and P. tolaasii, the causal organism of bacterial blotch disease of the mushroom, displayed a positive chemotactic response to Casamin...
Broad-host-range plasmids coding for beta-lactamase were successfully selected after transformation of Pseudomonas strains. Transformants of both Pseudomonas aeruginosa and Pseudomonas putida containing plasmid pRO1614 were isolated in media containing low concentrations of piperacillin. These strains were also susceptible to other ureidopenicillins. Similar selections of transformants with car...
چکیده استفاده از باکتری های محرک رشد علاوه بر افزایش رشد و عملکرد گیاه، کاهش مصرف کودهای شیمیایی و افزایش کارایی کود مصرفی را نیز به همراه دارند. به منظور تعیین اثر کاربرد باکتری محرک رشد گیاه pseudomonasputida به همراه مقادیر مختلف کود نیتروژن آزمایشی به صورت فاکتوریل در قالب طرح پایه بلوک های کامل تصادفی با سه تکرار بر گیاه سویا در شهرستان بیله سوار اجرا شد که در آن فاکتورهای آزمایش شامل دو...
background and objectives: sodium dodecyl sulfate (sds) is one of the most widely used anionic detergents. the present study deals with isolation and identification of sds-degrading bacteria from a detergent contaminated pond situated in varanasi city, india. materials and methods : employing enrichment technique in minimal medium (pbm), sds-degrading bacteria were isolated from pond water samp...
Confocal laser scanning microscopy was used to monitor the colonization pattern of the gfplabeled derivative strain of Pseudomonas putida ATCC 17514 on fluorene and phenanthrene crystals. The in situ experiments showed that P. putida tends to grow directly on phenanthrene, forming a biofilm on accessible crystalline surfaces. On the other hand, no significant biofilm formation was observed in t...
