Analysis of the isoenzymes of peroxidase and catechol oxidase of Armeniaca in Xin Jiang 新疆杏属植物过氧化物酶儿茶酚氧化酶同工酶分析
Characteristics of Catechol Response on the Amperometric Biosensor of Polyphenol Oxidase 儿茶酚在预活化聚酰胺膜多酚氧化酶电流传感器上的响应特性
At the stage of vegetative growth, the extracellular laccase and catechol oxidase activity were higher. 营养生长阶段,分解木质素的胞外漆酶和多酚氧化酶活性较高,在子实体生长期间,两种酶的活性呈减弱趋势。
While catechol oxidase, CMCase and hemicellulase needed higher C/ N. Their activity were higher at 40:1 or so. 多酚氧化酶、纤维素酶和半纤维素酶的分泌要求较高的C/N,在40∶1左右有高分泌活性。
During the mycelium growth, extracellular enzyme activity of laccase, catechol oxidase, CMCase and hemicellulase were related to some kind of carbon source or nitrogen source, while were not correlated to mycelial growth amount. 菌丝体生长过程中,胞外漆酶、多酚氧化酶、纤维素酶、半纤维素酶四种酶活性与某种碳或氮源的诱导有关系,而与菌丝的生长量无相关性。
Phenol is transformed into catechol by chitosan immobilized mushroom polyphenol oxidase. 利用壳聚糖固定化蘑菇多酚氧化酶催化氧化苯酚合成邻苯二酚,考察了固定化多酚氧化酶羟基化反应条件对目的产物产率的影响。
The yam polyphenol oxidase activity was determined spectrophotometrically at 410 nm with catechol as substrate, and effect of different pH, temperature, substrate concentration and inhibitor concentration on polyphenol oxidase activity was studied. 以邻苯二酚为底物,采用分光光度法测定波长410nm处山药多酚氧化酶的活性,研究了pH、温度、底物浓度和抑制剂对山药多酚氧化酶活性的影响。
Analysis of the isozyme of peroxidase and catechol oxidase of petiole and anther of 312 peach varieties indicated that the isozyme patterns of petiole and anther are significantly correlated with the flesh texture and pollen fertility respectively. 经对桃不同品种进行叶柄和花药的过氧化物酶及儿茶酚氧化酶同工酶分析,发现叶柄谱型和花药谱型分别与果实肉质类型及花粉稔性存在显著相关性;
