chitin n.【動物;動物學】(甲)殼質,明角質。

chitinous

They are characterized by having cell walls made chiefly of chitin , not the cellulose of plant cell walls , and they all develop directly from spores without an embryo stage 其特征如下:細胞壁主要由幾丁質構成,而不完全是植物細胞壁中的纖維素。

Abstract : a potential immobilized microorganisms supporter - chitin is reported , and it has been used in the wastewater biochemical treatment 文摘:介紹了一種極具潛力的微生物固定化載體? ?甲殼素,并應用于豆制品廠及精細化工廠廢水的生化處理。

The degradation of chitin by chitinase was vital step in the life cycle of insects because insects undergo periodic ecdysis and metamorphosis 幾丁質代謝隨昆蟲不同生長發育階段而變化并保持相對的穩定,對昆蟲的正常的生長發育是至關重要的。

Many fungi are rich in chitin and chitosan in their cell walls , which makes fungi become a new and potential source of chitin and chitosan 摘要不少真菌細胞壁中含有豐富的幾丁質和殼聚糖,使真菌成為生產幾丁質和殼聚糖的又一潛在的新來源。

Instead , bacteria possessing specialized chitinolytic enzymes cause the chitin to decay , helping recycle it swiftly back into the environment 相反,細菌擁有特殊的幾丁質(甲殼素)消化酶使甲殼素降解,有助于甲殼素迅即在環境中再循環。

Purified chitosan was extracted from chitins using sodium hydroxid . collagen then was mixed with 10 % chitosan to fabricate a highly porous membrane by lyophilization 以膠原與10殼聚糖共混,經凍干成膜,以0衛5戊二醛交聯。

For the high selectivity and safety of chitin synthase inhibitors , they are used for insecticides , fungicides and acaricides 幾丁質合成酶抑制劑由于具有安全、高效等特點,成為農用殺蟲、殺螨、殺菌劑以及醫藥抗真菌藥物的研發熱點。

They showed that mice without the cells did not launch an immune response , indicating that the macrophages signaled the presence of the chitins 他們的研究表明小鼠沒有該細胞不發動免疫反應,顯示巨噬細胞發出了甲殼素存在的信號。

Aeromonas sp . suwa - 9 is a bacterium isolated from the suwa lake of japan as a producer of several chitin - degrading enzymes 氣單孢菌aeromonassp . suwa - 9菌株是從日本國長野縣suwalake的湖水中分離到的細菌。

Chitin is one of the most abundant biological natrue resources , have many kinds of physiological functions 甲殼質,又名幾丁質,是自然界最豐富的生物資源之一,具有多種生理功能,廣泛應用于各種行業中。

Glucasmine is an amino sugar extracted from the chitin of shellfish that is used by the body to support healthy joint structures 葡萄糖氨是一種從貝類殼質中萃取的氨基糖,用于維持身體骨骼結構的健康。

Because chitin has a high degree of crystallinity , it can only be dissolved in expensive organic solvents 摘要由于天然甲殼素結晶度高,在濕法紡絲過程中溶解甲殼時需要使用價格較高的有機溶劑。

While humans and other vertebrates do not produce chitin , our bodies are equipped to recognize and eliminate it 雖然人類和其它脊椎動物不能產生甲殼素,當我們的身體能識別并清除甲殼素。

Applications of infrared spectroscopy and nuclear magnetic resonance spectroscopy in the studies of the structure of chitin and chitosan 紅外光譜與核磁共振波譜在甲殼素結構研究中的應用

Chitooligosaccharide is a kind of oligosaccharide which is made from chitin or chitosan by chemical or enzymatic decomposing method 它是甲殼質經脫乙酰基而得到的一種天然陽離子多糖。

In this paper , advances in the application and research of chitin deacetylase in preparation of chitosan are summarized 本文就甲殼素脫乙酰酶在殼聚糖制備中的應用及研究進展作一綜述。

Isolation of bacteria producing chitin - degrading enzymes and preliminary studies on their optimum fermentative conditions 幾丁質降解酶產生菌的分離及其產酶條件的初步研究

Chitin a nitrogen - containing polysaccharide found in the cell walls of most fungi and in some animals 幾丁質:在大多數真菌和一些動物的細胞壁中發現的含氮的多糖。

Manufacture chitosan a natural , biodegradable polymer fiber obtained through the deacetylation of chitin -從事塑料制品的研制開發和生產包括護欄, pvc護欄等。
