酸微菌目
英文
acidimicrobiales-
D - amino acids as unnatural chiral products are important intermediates in the synthesis of products, such as - lactam semisynthetic antibiotics, antiviral agents, artificial sweeteners, pesticide, peptide hormones, and pyrethroids, etc. though bioconversion of d - amino acids using microbial cells has been realized in industrialization for decades, some limited factors hinder the development of d - amino acid production, and ultimately result in shortage of the raw material in the related industrial fields
目前，用微生物菌體轉化生產d -型氨基酸的工藝路線已經產業化，但天然菌體轉化工藝存在一些限制因素，阻礙了d -型氨基酸的擴大生產，導致產品短缺。因此，利用基因工程菌生物轉化d -型氨基酸已成為世界氨基酸產業的新潮流。Quinic acid, used shikimate pathway in e. coli, it is necessary to extend metabolic pathway by introduction of a heterogenous gene qutb into the host cell. double specific enzyme genes arog, qutb or three ones arog, qutb, arob were co - expressed in a single plasmid pbv220 to improve the enzymes " rate - limiting reactions. modifications of e. coli chromosome by both disruption of the arod gene and directed - site insertion of the arob gene resulted in the change of carbon flow redirected into the quinic acid biosynthesis branch
利用大腸桿菌莽草酸途徑合成新的代謝物奎尼酸，須在宿主細胞引入異源酶基因擴展代謝途徑；串聯表達酶基因，同時適量增加不同種屬的多個關鍵酶酶量，改善限速反應；利用同源重組進行基因整合和基因破壞，改造染色體結構定向改變微生物代謝途徑；目的是將碳代謝流最大程度的引向奎尼酸生成的方向。Two kinds of them are widely studied at present. one is the substance whose surface has micro - pore structure or crystal structure with excellent exchanging prosperity, such as silver - zeolite ; the other one generally select the glass with certainly chemical stability and soluble property, which are added a few ag +, zn2 +, cu2 + ion
目前研究最廣泛的抗菌材料有兩類，一類是物質表面具有微孔結構或具有離子交換性能良好的層狀晶體結構如銀沸石等；另一類通常是選用有一定化學穩定性和水溶性的磷酸鹽和硼酸鹽系統玻璃微載體的含銀、銅、鋅的抗菌玻璃。The number of 3 rhizosphere microorganisms ( bacteria, fungi, actinomycete ) and 5 enzyme ( catalase, protease, urease, phosphatase, invertase ) activities were studied during the whole life of corn plant in sandy loam, loam and clay soil textures. [ method ] using yedan22, the number of 3 rhizosphere microorganisms and 5 enzyme activities with different textural soils were investigated in a pond
摘要目的明確不同質地土壤（砂壤、中壤、重壤）玉米生育期間根際微生物（細菌、放線菌、真菌）數量與酶（脲酶、蛋白酶、磷酸酶、轉化酶、過氧化氫酶）活性的變化。[ objective ] the number of 3 rhizosphere microorganisms ( bacteria, fungi, actinomycete ) and 5 enzyme ( catalase, protease, urease, phosphatase, invertase ) activities were studied during the whole life of corn plant in sandy loam, loam and clay soil textures.

摘要目的明確不同質地土壤（砂壤、中壤、重壤）玉米生育期間根際微生物（細菌、放線菌、真菌）數量與酶（脲酶、蛋白酶、磷酸酶、轉化酶、過氧化氫酶）活性的變化。However, its wide applications in manufacture are restricted by such a question as low phytase - producing level of wild strains, so before the wild strains which can produce acidic phytase are widely used, their phytase activities must be improved by various means in which using an efficient expression system to express heterogenous phytase is a main consideration
但微生物野生菌株產酶水平較低，制約了微生物植酸酶在生產上的廣泛應用，因此提高植酸酶野生菌株的產酶水平是實現其廣泛應用的關鍵所在。目前，提高野生菌株產酶水平的主要思路是通過基因工程手段克隆其植酸酶基因，然後在生物反應器中高效表達該植酸酶基因。However, the yield of d - amino acids has been tempered by some limited factors from strain per se resulting in the shortages of that goods in the markets. therefore, scientists are trying to substitute engineered strains for natural strains in the process described above
