1. induction of microbial cellulose(bio-cellulose) What is microbial cellulose (bio-cellulose)? Microbial cellulose is the cellulose produce from microorganism metabolism. Microorganism from the genera Aerobacter, Acetobacter, Achromobacter, Agrobacterium, Alacaligenes, Azotobacter, Pseudomonas, Rhizobium and Sarcina synthesize cellulose. However, only the Acetobacter species produce enough cellulose to justify commercial interest. The most extensively studied member of the Acetobacter species is A. xylinus, formerly known as A. xylinum. A.xylinus extrudes glucan chains from pores into the growth medium. These aggregate into microfibrils, which bundle to form microbial cellulose ribbons. If the nutrition enough for the microorganism, there will form a gel like membrane. In food industry, people call the jelly-like membrane “nata”. Nata de coco is a chewy, translucent food product produced by the bacterial fermentation of coconut water. The microbial cellulose also been used in medical device more than 10 years, and since 2002, several cosmetic manufacturer began to use this natural cellulose as essence carrier for face mask. 微生物的介绍： 纤维素（生物纤维素） 什么是微生物纤维素？ 微生物纤维素是由微生物新成代谢产生的。 微生物是由来自属产气，醋酸杆菌，无菌属，农杆菌，棕色菌，假性单胞菌，根瘤菌和八叠球菌等合成的纤维素。然而，只有醋酸杆菌产生的生物纤维能产生较高的经济效益。醋酸杆菌的物种中被广泛研究的一个成员是A杆菌，A挤压毛孔的葡聚糖链入培养基。这些生物微纤维，捆绑成一个带状纤维素结构。如果有足够的营养，它们将形成一个凝胶样的膜。 在食品领域，人们称这种果冻状的膜为“纳塔”。 椰果纳塔是一种耐嚼，半透明的，由椰子水细菌发酵生产的食品。 微生物纤维素也被用在医疗设备已有10余年，自2002年以来，一些化妆品生产商开始使用天然纤维素载体作为面膜的承载精华液的载体。 Process of Microbial cellulose produce by Acetobacter 醋酸菌产生微生物纤维的过程： Among the bacteria, one of the most advanced types of purple bacteria is the common vinegar bacterium, Acetobacter. This non-photosynthetic organism can procure glucose, sugar, glycerol, or other organic substrates and convert them into pure cellulose). 这些细菌中，紫色细菌中最为活跃的一种是常见的醋细菌，醋酸菌。这些非光和作用菌类可从葡萄糖，蔗糖，甘油或其他有机质中获得并把它们变成纯粹的生物纤维。Acetobacter xylinum is Natures most prolific cellulose-producing bacterium. 木醋杆菌是大自然最丰富的纤维素产生菌。Consider that as many as a mil
