The application of pesticides in agricultural fields not only reaches the target pests but also with soil where it interacts with soil microorganisms resulting in change of microbial diversity. Chlorpyrifos (CP) is one such organophosphorous insecticide most widely used against various insects, termites, and beetles throughout the globe. In the present work, the effect of CP on soil microbial p...
قرن هاست که از تخمیر برای حفاظت، بهبود کیفیت و یا اصلاح عطر و طعم حبوبات، میوه ها، سبزی ها، شیر و گوشت استفاده می شود. تاریخچه ترشی و شوری در ایران به زمان قوم ماد بر می گردد، در حالی که از عمر تولید صنعتی ترشی و شوری در ایران تنها70 سال می گذرد. سالاد زمستانه در واقع نوعی شوری تهیه شده از سبزی های مختلف است که در ایران و بخصوص در خراسان مصرف می شود. هدف از این پژوهش بررسی اثر سطوح مختلف شلغم ف...
دمولسیفایرهای شیمیایی که برای شکست امولسیونهای آب در نفت بکار میروند سمی هستند و اثرات زیانباری بر محیط-زیست دارند. به همین دلیل بیودمولسیفایرها به عنوان ترکیبات سازگار با محیط زیست به عنوان یک جایگزین مطرح هستند. هدف از تحقیق حاضر دستیابی به باکتریهای مولد بیودمولسیفایر است. برای این منظور با نمونهگیری از رسوبات نفتی، جدایههای مولد بیـودمولسیفایر با استفاده از روشهای غنیسازی د...
A strain of Vibrio sp. isolated from marine sediments produced large quantities of bright red pigments that could be used to dye many fibers including wool, nylon, acrylics, and silk. Characterization of the pigments by electrospray ionization mass spectrometry (ESI-MS) and nuclear magnetic resonance (NMR) revealed three prodiginine-like structures with nonpolar characteristics and low molecula...
Bile acids are surface-active steroid compounds with toxic effects for bacteria. Recently, the isolation and characterization of a bacterium, Pseudomonas sp. strain Chol1, growing with bile acids as the carbon and energy source was reported. In this study, initial reactions of the aerobic degradation pathway for the bile acid cholate were investigated on the biochemical and genetic level in str...
Intracellular RNAs of an avirulent small-plaque (SP) transmissible gastroenteritis virus variant and the parent virulent Miller strain of transmissible gastroenteritis virus were compared. Northern RNA blotting showed that the Miller strain contained eight intracellular RNA species. RNAs 1, 2(S), 5, 6(M), 7(N), and 8 were similar in size for both viruses; however, the SP variant lacked subgenom...
We used a "current signature" method to subclassify acutely dissociated dorsal root ganglion (DRG) cells into nine subgroups. Cells subclassified by current signature had uniform properties. The type 1 cell had moderate capsaicin sensitivity (25.9 pA/pF), powerful, slowly desensitizing (tau = 2,300 ms), ATP-activated current (13.3 pA/pF), and small nondesensitizing responses to acidic solutions...
A new actinomycete strain, designated US80 and producing antimicrobial activities against Gram-positive and Gram-negative bacteria and fungi, was isolated from Tunisian oasis soil. Cultural characteristic studies strongly suggested that this strain belongs to the genus Streptomyces. The nucleotide sequence of the 16S rRNA gene (1517 pb) of Streptomyces sp. strain US80 exhibited close similarity...
