this work examined the simultaneous saccharification and fermentation (ssf) process for the biological conversion rice wastewater into ethanol using co-culture of aspergillus niger (a. niger) and saccharomyces cerevisiae (s. cerevisiae) in batch condition. in this study, the a. niger and s. cerevisiae were used for hydrolysis and production of ethanol from rice wastewater, respectively. the effe...
ژن fry1 در گیاه آرابیدوپسیس یک ژن واکنشگر به تنش های غیر زیستی است که آنزیمی با دو کارکرد 3 (2) 5- بیس فسفات نوکلئوتیدازی و اینوزیتول پلی فسفات 1-فسفاتازی را کد می کند. فعالیت اینوزیتول پلی فسفات 1-فسفاتازی پروتئین fry1 نشان می دهد که این پروتئین به عنوان عامل کاتابولیسم اینوزیتول 1، 4، 5، تری فسفات (ip3) در مسیر پیام رسانی فسفواینوزیتید نقش دارد. نقش دیگر fry1، تجزیه ی فسفوآدنوزین 3، 5- بیس فس...
Rhodospirillum rubrum was shown to grow fermentatively on fructose with N2 as a nitrogen source. The nitrogenase activity of these cells was regulated by the NH4+ switch-off/switch-on mechanism in a manner identical to that for photosynthetically grown cells. In vitro, the inactive nitrogenase Fe protein from fermenting cells was reactivated by an endogenous membrane-bound, Mn2+-dependent activ...
ایمونوتوکسینها برای درمان سرطان در حال توسعه هستند. آنها از آنتی بادیهای متصل به توکسین مانند اگزوتوکسین پسودوموناس تشکیل میشوند. از طرف دیگر فاکتور رشد اندوتلیال عروقی (vegf) در آنژیوژنزیس تومور نقش دارد و مهار vegfr-2 آنژیوژنزیس و رشد تومور را مهار میکند. هدف از این مطالعه تولید ایمونوتوکسین anti-vegfr2/rpe38، ارزیابی فعالیت سایتوتوکسیسیتی و مکانیسم عملکرد آن در in vitro بود. برای تولید ایمون...
background & aims of the study: in this research, long-term hydrologic impact assessment model is selected for simulation of runoff and nps pollution. the aim of this study is modeling of non-point source pollution by l-thia model in zayandehrood watershed in 2015. materials & methods: in this study, analytical survey and investigation of references in the context of library studies has been us...
dianchi lake is one of the most three seriously eutrophic lakes in china. in the present study, the phosphorus (p) and nitrogen (n) fractions in 37 surface sediments samples collected in the dianchi lake were investigated. the total phophorus (tp) in sediments was divided into two parts: inorganic p (ip) and residual p (res-p). the results showed that the total phosphorus content in surface sed...
Sunn hemp (SH, Crotalaria juncea, L.) is a tropical multiple-purpose legume. The green manure SH (GMSH) crop might display protein ecology in sustaining ruminants; however, its silage features remain unclear. To efficiently prepare GMSH silage, additive treatments consisting of control (no additive, CON), molasses (MO), Acremonium cellulase (AC), and Lactobacillus casei TH14 strain inoculant (T...
The evolutionary conserved TOR complex 1 (TORC1) activates cell growth in response to nutrients. In yeast, TORC1 responds to the nitrogen source via a poorly understood mechanism. Leucine, and perhaps other amino acids, activates TORC1 via the small GTPases Gtr1 and Gtr2, orthologs of the mammalian Rag GTPases. Here we investigate the activation of TORC1 by the nitrogen source and how this migh...
In order to investigate the effect of source and rate of nitrogen fertilizer on yield and quality of sweet corn, a field study was conducted in 2011 cropping season in Agriculture Experiment Station of College of Agriculture, University of Guilan. A randomized complete block design with three replications was used. Treatment consisted of four levels of nitrogen fertilizer (0, 46, 92 and 138 kg ...
background: based on recent studies, there are controversial reports on the ca-pacity of tissue cyst forming of toxoplasma gondii rh strain. in this study, the capac-ity was evaluated by in vivo and in vitro experiments. methods : rh strain was subcutaneously inoculated to ten wistar rats. after one month, their blood, brain, tongue and diaphragm were collected and evaluated by mat, pcr, pathol...
