Hydrogen peroxide (H 2 O 2 ) content and catalase activity were studied in pea ( Pisum sativum L.) seedlings with a normal (cultivar Marat) and disrupted (pea mutants) process of nodulation that were inoculated with the nitrogen-fixing bacterium Rhizobium leguminosarum strain CIAM 1026. ...
The involvement of hydrogen peroxide (H_20_2) metabolism and catalase activity in dormancy release and sprouting of potato (Solarium tuberosum L.) tubers has been investigated in nine cultivars with a contrasting dormancy length. Phenotypic characterisation of tubers dormancy was established for all ...
IN a recent letter1 Johnson and van Schouwenburg dispute Keilin and Hartree's observation2 that catalase activity depends on the presence of oxygen. In their reply, Keilin and Hartree3 point out that the experiments of Johnson and van Schouwenburg are only qualitative and therefore not ...

Hydrogen peroxide-induced astaxanthin biosynthesis and catalase activity in Xanthophyllomyces dendrorhous 来自 EBSCO 喜欢 0 阅读量: 130 作者:SL Yuan,YW Jian 摘要: Xanthophyllomyces dendrorhous (formerly Phaffia rhodozyma ) in shake-flask cultures was exposed to 10–20mmol/L H 2 O 2 at ...
1、过氧化氢的测定方法(Methods for determination of hydrogen peroxide)Three, catalase activity - ultraviolet absorption methodprinciple H202 has a strong absorption at 240nm wavelengths, and hydrogen peroxide decomposes hydrogen peroxide, reducing the absorbance (A240) of the reaction solution with ...
The effect of water–alcohol (methanol, ethanol, propan-1-ol, propan-2-ol, ethane-1,2-diol and propane-1,2,3-triol) binary mixtures on the kinetics of hydrogen peroxide decomposition in the presence of bovine liver catalase is investigated. In all solvents, the activity of catalase is sma...
This study aimed to develop an effective and safe decoloring system for soy-based protein products using food-grade hydrogen peroxide and catalase. First, soy-based protein isolate (PI) and textured vegetable protein (TVP) were treated with hydrogen peroxide, and then the residual hydrogen peroxide...
Effects of H2O2-producing lactobacilli on Neisseria gonorrhoeae growth and catalase activity. Hydrogen PeroxideCatalaseHydrogen-Ion ConcentrationIn the vagina and endocervix, Neisseria gonorrhoeae must interact with complex microflora. Among these are ...

Catalase pretreatment prevented the GO-induced stimulation of TGF-β1 mRNA. When incubations were performed with a panselective neutralizing anti–TGF-β antibody, the GO-stimulated expression of ECM molecules was prevented. Conclusions GO-induced hydrogen peroxide production induces TGF-β1 synthesis ...
