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 ...

DONALD K. WALTER

Mr. Don Walter should be commended for his technical paper dealing with the real-world problems of preparing anaerobic digester feeds from a difficult raw material, municipal solid waste (MSW). The information presented in the paper is not readily available in the published litera­ ture, and will be valuable to engineers interested in MSW processing and digestion. The author discusses some of t...

Maize and solvent extracted soybean meal (SBM) were ground through a 2 or 3 mm screen, resulting in “fine” and “coarse” material. The mean particle sizes of fine and coarse feed were 0.62 vs. 0.96 mm (maize) and 0.63 vs. 1.01 mm (SBM). Maize or SBM of either particle size was included in experimental diets at two different levels at the expense of maize starch. Three week old broilers had free ...

This article describes the effect of particle size distribution, pellet size and dehydration techniques on the improvement of physical properties of the pelleted feed products. It is shown that dehydration with vacuum has positive effect on durability when compared to air technique. Products volume and particle size distribution also had an effect on physical properties. INTRODUCTION In porous ...

Two experiments with 14- to 35-d-old male broilers were performed to investigate the interactions between increasing levels of balanced protein (BP; 9.7, 10.7, 11.7, and 12.7 g of digestible Lys/kg of feed) and physical feed form. In Experiment 1 diets were offered as coarse mash and pellets of either good or poor quality. Good pellet quality was characterized by high durability. In Experiment ...

The partitioning of polycyclic aromatic hydrocarbons (PAHs) between the particulate and gaseous phases resulting from the combustion of polystyrene was studied. A vertical tubular flow furnace was used to incinerate polystyrene spheres (100-300 μm) at different combustion temperatures (800-1200 °C) to determine the effect of temperature and polystyrene feed size on the particulate and gaseous e...
