in protein biochemistry, biochemists specially study proteins as complex polymers. protein biochemistry is the study of the chemical structure of proteins, including individual amino acids, their linkage as well as physical structure of proteins. proteins, especially globular proteins, are three dimensional in nature. proper function of globular proteins is tightly related to their three-dimens...
با توجه به شیوع سرطان در جوامع امروزی، یافتن داروهای جدید برای درمان آن از اهمیت بالایی برخوردار است. استفاده از داروهای شیمیایی موجود به دلیل عوارض جانبی که دارند با محدودیت مصرف روبه رو می باشند. از این رو محققین درصدد یافتن مواد طبیعی با خاصیت ضد سرطانی می باشند. هدف اصلی این پایان نامه بررسی اثرات ضد سرطانی lactoferrin وwhey acidic protein موجود در شیر شتر می باشد. در تحقیق حاضر تأثیر lacto...
materials and methods the expression of hyaluronidase antigenic fragments was optimized using iptg concentration, time of induction, temperature, culture, and absorbance of 0.6-0.8-1 at 600 nm. afterwards, the expressed proteins were purified and the enzymatic activity was assessed by turbid metric method. results data indicated that maximum protein is produced in od = 0.8, 0.5 mm isopropyl β-d...
Two experiments were conducted to evaluate the crude protein fractionation, in vitro gas production and the biological effects of tannins in alfalfa silage treated with different levels of pistachio by-products (PB) extract. PB was soaked in water with a ratio of 1:5 (w/v) for 12 h. After filtering and concentrating, the crude extract was added to fresh alfalfa to a final concentration of 1%, 2...
Recombinant protein production in Pichia pastoris is based on alcohol oxidase promoterswhich are regulated by methanol. However, the use of methanol has several disadvantages,which is why current trends in bioprocess development with Pichia pastoris (P. pastoris) arefocusing on methanol mixed feeding strategies. This work aimed to develop a new experimentalmethod and compare the effect of vario...

Production of single cell protein (SCP) from natural gas in a one liter bubble column reactor and optimization of the process parameters were investigated. The medium specifications, nitrogen sources, initial inoculum volume, and inlet ratio of gas to air were considered as process parameters to be optimized. The optimum condition for highest biomass production in which the maximum quantity of ...
an experiment was conducted to evaluate the effect of dietary crude protein and lysine levels on quality and quantity of egg production. fifteen diets consisted of 3 levels of protein (14, 15 and 16%) and 5 levels of lysine (0.71, 0.74, 0.77, 0.80 and 0.83 %) in a 35 factorial arrangement were provided. each diet was randomly fed to 4 replicates of 12 birds, during four periods of 4 weeks (28-...
today, by increase in production capacity of dairy manufactures, high amounts of whey is produced as a by product of cheese production. in recent decays, high amount of whey production sometimes up to 8 times more than produced cheese-, its high bod and its environmental problems caused in particular attention to whey processing and its usage in food products. according to promotions occurred i...
background: as a drug target and an antigenic agent, hiv-1 protease (hiv-1 pr) is at the center of attention for designing anti-aids inhibitors and diagnostic tests. in previous studies, the production of the recombinant protease has been faced with several difficulties; therefore, the aims of this study were the easy production, purification of the soluble form of protease in e. coli and inves...
