آلودگی میوه پسته به گونه های زهرابه زای aspergillus یکی از معضلات جامعه بشری در امر سلامت و امنیت مواد غذایی انسان و دام می باشد. به منظور ارزیابی کنترل بیولوژیکی قارچ a. flavus توکسین زا و بررسی توکسین زدایی در شرایط آزمایشگاهی، طی تابستان سال 1388 تا 1389 نمونه برداری از خاک سطحی و ریزوسفر مناطق مختلف استان کرمان، خراسان رضوی و یزد صورت گرفت. قارچ a. flavus از خاک منطقه فیض آباد نوق از توابع ...
biological control of root-knot nematode meloidogyne javanica by application of pseudomonas fluorescens cha0 was evaluated under greenhouse condition. results showed that p. fluorescens (109 cfuml-1) as shoot spray significantly reduced in no. of eggmass and egg per individual eggmass as comparison to control. application p. fluorescens as shoot spray induced systemic activation of peroxidase (...
Tomato is the second most important vegetable crop. It widely grown on all over world. Diseases are major constraint in economic crop production as they inflict heavy loss tomato. Among various fungal diseases, early blight was reported severe it causes damage to The main aim of this study explore potentiality native and efficient isolate P. fluorescens biocontrol agent. A total 30 Pseudomonas ...
Bacillus cereus, Clostridium perfringens, Staphylococcus aureus, Pseudomonas fluorescens, Pseudomonas fragi, Escherichia coli, and Salmonella "anatum" were challenged with butylated hydroxyanisole (BHA). Susceptibility was measured as the concentration of BHA required to cause a 90% reduction in bacterial survivors. Staphylococcus aureus LP and P. fragi were two of the most resistant species ex...
Siderophores are iron chelating substances that are also known to bind metals such as Molybdenum and Lead. The pigment produced by P. fluorescens is a siderophore whose ability to bind to different metal ions was investigated in this study. Pigment production was increased in the presence of Sodium, Potassium, Lead, Molybdenum and Cadmium. Siderophores were detected using CAS assay and catechol...
Kalimantacin A and batumin exhibit potent and selective antibiotic activity against Staphylococcus species including MRSA. Both compounds are formed via a hybrid polyketide synthase/non-ribosomal peptide synthetase (PKS-NRPS) biosynthetic pathway and from comparison of the gene clusters it is apparent that batumin from Pseudomonas batumici and kalimantacin from P. fluorescens are the same compo...
Red cabbage is known as the millennium’s functional food, which has a lot of importance in our diet because health-promoting ingredients present it. The current study investigated synergistic relationship rhizospheric-competent microbial agents (Trichoderma harzianum, Pseudomonas fluorescens, and Bacillus subtilis) modulating performance red under field conditions Middle Gangetic Plains, India....
Background: Natural plant extracts and microbial antagonists have the potential for use in increasing fungal resistance productivity of horticulture plants. Methods: The purpose this study was to evaluate ability both natural as a biotical control some pathogens, i.e., Fusarium ssp., Exserohilum ssp. Nigrospora along with improving growth performance zucchini under greenhouse conditions. Eucaly...
