动物纤维素

A cellulose cuprammonium solution was sprayed into the -40℃ frozen liquid containing 20% Silicone oil and 80% hexane to form microspheres contained fine ice crystals,then regenerated the cellulose with 40% H 2SO 4 cooled to -30℃,and the microspheres were modified with diethylaminoethylchloride,the cellulose porous microcarriers for animal cell culture were prepared.

将纤维素铜氨溶液喷洒至－40℃的硅油：正己烷＝1：4的冷冻液中形成含冰晶的微球，用－30℃、40％的H2SO4再生纤维素，并用EDAE盐酸盐修饰其表面，制成适合动物细胞培养的纤维素多孔微载体。

Insects polysaccharide from insect crust are a natural macromolecular polymers that remove behind the acetyl group getting usually that paries draw, which are currently found only bring positive charge of the animals cellulose in the natural world- containing amino polysaccharide of high-molecular compound.

昆虫多糖是从昆虫体壁提取的甲壳素脱去乙酰基后得到的一种天然高分子聚合物，也是目前发现的自然界中唯一带正电荷的可食性动物纤维素——含氨基多糖的高分子化合物。

Many experimental results showed that the addition of appropriate amount of cellulase in animal feed can increase the utilization rate of feed and quicken the growth of animals, and the effect on ruminant animals is especially remarkable.

许多实验结果表明：在动物饲料中添加适量的纤维素酶可以提高饲料的利用率和动物的生长速度，对反刍动物的效果尤为明显。

Most plants have cellulose cell walls,and have starch as a storage polysaccharide, whereas animals have no cell walls, store glycogen, and do not have plastids or chlorophyll;and fungi usually lack cellulose and also do not form plastids.

大多数植物具有纤维素细胞壁，以淀粉形式储存多糖，而动物没有细胞壁，储存糖原，没有质体或叶绿素；真菌通常缺乏纤维素，也不形成质体。

The hotspot in chitosan study is to increase its solubility and the adsorptive capability of Cu.

壳聚糖是一类带阳离子的动物纤维素和自然界唯一天然碱性多糖(图1)。

Chintin used to produce thin films of material abundance in nature, there are quite a few Insecta or crustaceans of the shell is made by chintin ——— a non-crystalline polycarbohydrates, its chemical composition is celluiose, and chintin cellulytic, is the production of films by main ingredient.

用来生产甲壳薄膜的原料非常丰富，在自然界，有相当一部分昆虫纲或甲壳纲动物的外壳，是由甲壳质———一种非晶质多聚糖构成，它的主要化学成分是纤维素，而纤维素，正是生产甲壳薄膜的主要原料。

Feed cellulase is the key to develop and utilize cellulose Animal nutritive resources.

饲料纤维素酶是开发和利用纤维素作为动物营养源的关键，其研究和应用前景广阔。

Chitosan from the essence, is an animal cellulose, so it has the universal and the role of dietary fiber, it can absorb water, increasing stool volume, the promotion of gastric peristalsis; can effectively inhibit the gastrointestinal tract of harmful bacteria and promote the beneficial bacteria growth.

甲壳胺从本质上来说，是一种动物纤维素，因此它具有食物纤维的通性与作用，它能吸收水分、增加大便容积，促进胃肠蠕动；能有效抑制胃肠道有害菌并促进有益菌生长。

Result Nutrient components could induce corresponding gastrointestinal digestive enzymes of crayfish at dietary protein or cellulose level of 0, 33%, 50%, comparing to starch 0, 33%; Animal protein and cellulose at high level were beneficial for the SOD, while starch was opposite. Liver glycogen of crayfish fed with high-protein diets were even higher than these with highcarbohydrate diets, meanwhile, the muscle glycogen apparent consistent with the content of carbohydrate. Overall, crayfish was well adaptable to change in the dietary composition.

结果］饲料营养组分对鳌虾肠胃消化酶有良好的诱导作用，即：动物蛋白和纤维素均在0、33%、50%时可引起相应消化酶的适应性上升，而淀粉仅在0、33%时可引起淀粉酶上升；较高的动物蛋白和纤维素有益于肌肉中SOD的提高，而高淀粉则会显著降低鳌虾SOD值；肝糖原在高蛋白情况下能不受饲料中淀粉含量下降的影响，肌糖原则与淀粉含量保持一致；各生化指标经一定天数的波动后趋于稳定。

This study found that there was different digestibility of the cellulose and hemicellulose of roughage between individual sheep mainly because of the difference of digestibility on NEH part by the animal,and therefore it is suggested that the interest in the digestion of fiber material by ruminants should be focused on the digestion of NEH part.

在动物营养研究中，饲料中的纤维素类物质通常被分为纤维素、半纤维素和木质素[1，2]，但实际上这样分类的纤维素、半纤维素自身的营养价值或消化率是有差异的，因为纤维素可以分为结晶型和非结晶型的[3，4]，并且在植物体内纤维素和半纤维素并不是单独存在的，有相当一部分是与木质素

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
