Wood extractives, commonly referred to as pitch, cause major problems in the manufacturing of pulp and paper. Treatment of nonsterile southern yellow pine chips for 14 days with Pseudomonas fluorescens, Pseudomonas sp., Xanthomonas campestris, and Serratia marcescens reduced wood extractives by as much as 40%. Control treatments receiving only water lost 11% of extractives due to the growth of ...

گل جالیز انگل ریشه بسیاری از گیاهان دولپه‏ای مانند گوجه فرنگی، خیار، خربزه، توتون و غیره می‏باشد. این انگل در بیشتر مناطق گوجه کاری، به خصوص شمال غرب کشور گسترش داشته و به صورت یک مشکل عمده بروز کرده است. جدایه های آنتاگونیست قارچی fusarium spp. و باکتریایی pseudomonas fluorescens به عنوان عوامل بیولوژیک موثر در کنترل بیولوژیک این علف هرز شناخته شده هستند. در این راستا در سال زراعی 1390 نمونه ب...

در این تحقیق میزان تغییرات برخی ترکیبات دفاعی گیاهی از جمله آنزیم پراکسیداز و میزان فنل کل در میوه سیب رقم زرد، پس از مایه زنی با یک جدایه آنتاگونیست باکتری pseudomonas fluorescens و قارچ penicillium expansum بررسی شد. برای این منظور از جدایه p. fluorescens f7 که کارایی آن در کنترل بیماری کپک آبی سیب قبلاً به اثبات رسیده­بود، استفاده شد. استخراج و اندازه گیری آنزیم پراکسیداز و فنل کل به ترتیب در...

BACKGROUND Multiple independent culture-based studies have identified the presence of Pseudomonas aeruginosa in respiratory samples as a positive risk factor for bronchiolitis obliterans syndrome (BOS). Yet, culture-independent microbiological techniques have identified a negative association between Pseudomonas species and BOS. Our objective was to investigate whether there may be a unifying e...

Pseudomonas fluorescens strain 2-79, a natural isolate of the rhizosphere of wheat (Triticum aestivum L.), possesses antagonistic potential toward several fungal pathogens. We report the draft genome sequence of strain 2-79, which comprises 5,674 protein-coding sequences.

Biofield therapies have been reported to improve the quality of life as compared to other energy medicine. The aim of the study was to evaluate the impact of Mr. Trivedi’s biofield energy treatment on Pseudomonas fluorescens (P. fluorescens) for antimicrobial sensitivity, minimum inhibitory concentration (MIC), biochemical reactions, and biotype number. P. fluorescens cells were procured from M...

The intercellular washing fluid (IWF) of Malus domestica cv. Holsteiner Cox before and after application of the non-pathogenic bacterium Pseudomonas fluorescens Bk3 to the leaves was investigated in a comparative manner. SDS-PAGE in combination with ESI Q-ToF mass spectrometry, and homology search in relevant data bases revealed the highly up-regulated expression of several pathogenesis-related...

Campania's buffalo mozzarella is a greatly appreciated cheese in Italy and worldwide. From a microbiological standpoint, it is a highly perishable food and potentially at risk of contamination by pathogens such as Listeria monocytogenes (L. monocytogenes). The present paper reports the results of a challenge test carried out to assess the population dynamics of L. monocytogenes, alone and in pr...

Pseudomonas fluorescens strains that produce the polyketide antibiotic 2,4-diacetylphloroglucinol (2,4-DAPG) are among the most effective rhizobacteria that suppress root and crown rots, wilts, and damping-off diseases of a variety of crops, and they play a key role in the natural suppressiveness of some soils to certain soilborne pathogens. Root colonization by 2,4-DAPG-producing P. fluorescen...

A chromosomal locus encoding biosynthetic genes for a putative peptide synthetase of Pseudomonas fluorescens was identified and cloned. To achieve this, two sets of degenerated oligonucleotide primers KAGGA:SGTTG and TGD:LGG were used in PCR. These primers were selected based on highly conserved units of known peptide synthetases involved in adenylation and thiolation regions of Bacillus subtil...
