Активність каталази у ґрунтах лісових біогеоценозів присамар’я
Catalase activity in the soil of the wood biogeocenoses in the Samara-river region

Summary/Abstract: Research of catalase activity changes in connection with the free-radical oxidation is soil of natural and artificial ecosystems is conducted. The catalase is a plants’ enzyme of antioxidative protection. The catalase activity is a marker of variety and improvement of soils. It is important for the problems solutions in applied soil science. The aberrations of catalase, peroxidase and polyphenol oxidase activities characterise not only the metabolizing of plants, microorganisms and soils, but the level of the environmental pollution. The general activity of enzymatic systems allows ascertaining their role in the forming of biota components’ resistance to the exogenous influence. The seasonal dynamics of the soils’ catalase activity subject to the type of a biogeocenosis is disclosed.
