An alkaline cellulase from Bacillus sp. HSH-810 was purified 8.7-fold with a 30% yield and a specific activity of 71 U mg−1 protein. It was optimally active at pH 10 and 50 °C and was stable from pH 6 to 10 with more than 60% activity remaining after heating at 60 °C for 60 min. The molecular mass of cellulase was 80 kDa. It was inhibited by 50% by Fe3+ (1(More)
In this study, we investigated the effect of spinach saponin-enriched lipophilic fraction (SSEF) on collagen (10 μg/mL)-stimulated platelet aggregation in vivo. Dietary SSEF dose-dependently inhibited collagen-induced platelet aggregation by decreasing thromboxane A₂ production and intracellular Ca²⁺ agonist activity as an aggregation-inducing autacoidal(More)
