Synthesis of Cellulose by Acetobacter Xylinum
Appearance of cellulose microfibrils in the medium of a suspension of cells of Acetobacter xylinum in buffered glucose solution was preceded by a stage during which the cellulose in the medium was amorphous within the available resolution. The size of the vertical axis of the microfibrils of the bacterial cellulose was found on the basis of measurement of shadow length to be only about 16 A. In...
متن کاملتولید و تعیین مشخصات سلولز باکتریایی با استفاده از باکتری Acetobacter xylinum ATCC 10245
سابقه و هدف: سلولز باکتریایی با الیافی حدود 100 مرتبه کوچک‌تر از سلولز گیاهی دارای خصوصیاتی چون الاستیسیته زیاد، استحکام مرطوب بالا و قابلیت تطبیق‌پذیری می‌باشد. یکی از کاربردهای عمده آن در مهندسی بافت به‌عنوان ماتریس خارج سلولی سه بعدی برای پیوسته نگه داشتن سلول‌ها و کنترل ساختار بافت و تنظیم رفتار سلولی است. این تحقیق با هدف تولید سلولز باکتریایی و بررسی مشخصات آن صورت گرفت. مواد و روش‌ها: ...
متن کاملMathematical Modeling Of Bacterial Cellulose Production By Acetobacter Xylinum Using Rotating Biological Fermentor
Bacterial cellulose (BC) has a basic cellulose structure that gives high purity, high crystalline ability, high mechanical strength, and high water holding capacity. During the last few decades, BC has gained as an important biomaterial because of these unique physical and chemical characteristics. BC is synthesized by Acetobacter xylinum extracellularly in a suitable substrate media. Researche...
متن کاملProduction of Bacterial Cellulose by Acetobacter Xylinum: Effects of Carbon/nitrogen-ratio on Cell Growth and Metabolite Production
The effects of carbon/nitrogen ratios on production of bacterial cellulose (BC), by submerged cultivation of Acetobacter xylinum NUST4.2, were investigated using central composite design and response surface analysis. The accumulation of metabolite was linked to cell growth. Amongst organic sources, peptone was favorable for BC production, while glucose was observed as the best carbon source. T...
متن کاملThe relationship between cellulase activity and oligosaccharides and cellulose productions by Acetobacter xylinum ATCC 23769
We have tried to investigate various carbohydrates production and cellulose degrading enzyme activity in the culture broth of cellulose producing microorganism, Acetohacter xylinum to clarify the role of cellulase for cellulose production. Carboxymethylcellulose (CMC) degrading activity and various oligosaccharides in addition to cellulose have already been detected after one-day culture. These...
