چکیده توان بالقوه تجاری سلولازها و کاربردهای گوناگون آن ها در بسیاری از صنایع انگیزه ای قوی برای تحقیق در این زمینه طی چند دهه گذشته بوده است. با توجه به کاربردهای فراوان این آنزیم در صنایع غذایی? در این پژوهش تصمیم به جداسازی ریزسازواره های تولید کننده سلولاز از خاک درختان انار، انگور، خرمالو و گردو حیاط دانشکده کشاورزی تربیت مدرس، گرفته شد. در این بین خاک درخت خرمالو به دلیل دارا بودن تعداد ...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
A computer model of the fungal colony that grew consuming limited amount of nutrient with three control parameters, growth rate, and nutrient level and diffusion, was constructed to make a basic morphology diagram of mycelial colony. To apply the diagram with those parameters to the mycelial growth of Aspergillus nidulans wild and mutant strains, the relation between the colony expansion and th...
in this study , samples of oily nuts using for human consumption ( pistachio- peanuts- walnut …..) were randomly obtained from markets in three geografical regions (south, east and west) of tehran. they were immidiatedly sent to mycology lab. then they were prepared for detection of fungi on sabour glucose , rose bangal and chapex agars. analysis of fungi were done by slide-culture, detection o...
Three kinds of sclerotia of Typhula spp. from Ardabil, East Azerbaijan and Qazvin Provinces in the northwest of Iran were collected. Morphology and ITS sequences of rDNA suggested that the collected fungi belonged to Typhula incarnata Lasch, Typhula phacorrhiza (Reichardt) Fr. and Typhula sp. These three taxa are new records in the Middle East and the result of this research suggests that Iran ...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
