| | The recent advance on research of cellobiose oxidoreductases for lignocellulosics degradetion has been reviewed in this paper. When grown on cellulose, Phanerochaete chrpeosporium produces two eXtracellular cellobiose oxidoreductases: cellobiose dehydrogenase (CDH) and cellobinse : quinone oxidoreductase (CBQ), These two enzymes can oxidize cellobiose and cellodextrins and have a variety of electron acceptors.CDH can even oxidize cellulose. Both the enzymes have cellulose-binding sit... | | 本文综述了纤维二糖氧化还原酶降解木质纤维素的最新进展。黄孢原毛平革菌生长在纤维素上时生成两种胞外纤维二糖氧化还原酶即纤维二糖脱氢酶和纤维二糖醌氧化还原酶,它们可以氧化纤维二糖及纤维素糊精,有多种电子受体.纤维二糖脱氢酶还可以氧化纤维素,酶分子中均含有纤维素吸附位点。纤维二糖存在时这两种酶能还原醌和苯氧基。因此推测这些酶在木质纤维素降解中起调节作用。在其它一些真菌中亦发现此类酶的存在。 | | 文摘来源 | | Silent discharge plsama is a kind of un equilibrium plasma, it can be used for a series of fields such as plasma chemistry, UV and UVU light source and excitation of gas lasers, etc. The advance on research of the silent discharge and its application will be introduced briefly in this paper. | | 无声放电等离子体是一种非平衡态等离子体,它可用于等离子体化学、紫外与真空紫外光源以及气体激光器激励等方面。本文将概要介绍无声放电及其应用的研究进展。 | | 文摘来源 | | The recent advance on research methods of genes inducible expression was introduced. Cis elements(G box? GT 1 binding site? GCC box?W box) related to the inducible expression of ABA? ethylene? fungal elicitor inducible expression and transcription factors(GBFS? GT 1? EREBPS? WRKY)interacting with the above inducible elements were summarized. In addition, the molecular mechanism of this process was reviewed. | | 介绍了基因诱导表达调控的研究方法 ,并概述了与ABA、乙烯、真菌激发子诱导表达相关的顺式作用元件 (G box、GT 1结合位点、GCC box、W box) ,以及与这些顺式作用元件相互作用的转录因子 (GBFS、GT 1、EREBPS、WRKY)。同时对植物基因诱导表达调控的分子机制作了综述 | | 文摘来源 | |   | | << 更多相关文摘 |
