摘要: 土壤氧化还原酶是存在于土壤中的一种重要酶类,参与土壤中为数众多的重要生物化学反应,与土壤中有机物质的转化、腐殖质的形成以及土壤肥力变化密切相关.其催化反应的动力学研究常用来阐明其催化过程的特性、酶的本质属性及其对环境变化的响应等.研究土壤氧化还原酶动力学特征对探讨其来源、性质及影响因素,对进一步调控多种营养元素参与的反应过程有重要意义.文中概述了土壤氧化还原酶动力学研究的理论基础,综述了土壤氧化还原酶催化动力学研究的进展和影响因素,并对今后的研究提出了几点建议.

Abstract: Soil oxidoreductase is a group of enzymes catalyzing many important soil biochemical reactions and concerning with the transformation of soil organic matter,formation of humic substance,and dynamics of soil fertility.The catalytic kinetics of oxidoreductase can illuminate its catalytic characteristics, substantial properties,and response to environmental changes.This paper summarized the research advance of its kinetics,and proposed some comments in understanding its action mechanism and in regulating its catalytic processes.
