abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
An antifungal bacterial strain, isolated from a greenhouse soil sample, inhibits growth of microflora nearby. It was selected for further studies of bacterial antifungal properties. This isolate was identified as a Pseudomonas sp. based on carbohydrate utilization, and other biochemical and physiological tests. Petri plate assay revealed that the Pseudomonas sp. exhibited antifungal activity ag...
Pseudomonas CMR12a was previously selected as an efficient biocontrol strain producing phenazines and cyclic lipopeptides (CLPs). In this study, biocontrol capacity of Pseudomonas CMR12a against Rhizoctonia root rot of bean and the involvement of phenazines and CLPs in this ability were tested. Two different anastomosis groups (AGs) of Rhizoctonia solani, the intermediately aggressive AG 2-2 an...
these days, all department stores make an effort to provide their clients with valuable products in order to project the best image for them. as a result, clients’ comprehension risk will decrease and they will be more willing to repurchase. having a good image is really important for the department stores because it makes an impression on clients’ comprehension of both quality and risk. consid...

Antifungal Activity of Methanolic Extracts of Some Indigenous Plants against Common Soil-borne Fungi
Present study was conducted to evaluate the fungicidal property of methanolic extracts of some indigenous plants of Karachi such as Hibiscus rosa-sinensis (leaves), Thespesia populnea (leaves, stem and fruit), Withania somnifera (leaves and stem), Solanum surattense (shoot) and Melia azedarach (fruit) against common soil-borne phytopathogens viz., Macrophomina phaseolina, Rhizoctonia solani and...
This study aims at identifying the major soil borne pathogens of tomato associated with damping-off in nursery areas. To achieve this, nurseries plant pathology farm our area has been investigated. Samples symptoms were collected and cultured under aseptic conditions. Fungi isolated from diseased stem roots on potato dextrose agar (PDA) medium. Growing colonies fungi purified by single spore hy...
جهت شناسایی قارچ های عامل پوسیدگی طوقه و ریشه ی چغندرقند در سال زراعی 92-91 ضمن بازدید از مناطق عمده کشت چغندرقند در استان لرستان، ازگیاهان دارای علائم پژمردگی و پوسیدگی ریشه و طوقه چغندرقند نمونه برداری انجام شد. قطعات جدا شده از حد فاصل بافت های آلوده و سالم، پس از ضدعفونی سطحی بر روی محیط عصاره سیب زمینی، دکستروز و آگار (pda) کشت شدند. مطالعات بیماری زایی در شرایط گلخانه در خاک سترون با استف...
Fusarium wilt caused by Fusarium oxysporum Schltdl. f.sp. phaseoli (Fop), is one of the important diseases of the common bean in Iran and many of the bean growing countries. Incidence of the disease has been reported in tropical and semi-tropical regions of the world. This study was carried out to characterize genetic diversity of F. oxysporum isolates from the common bean by vegetative compati...
