Abstract Kombucha is a beverage obtained by the fermentation of sugared tea with tea fungus. The tea fungus converts the sweetened tea to a refreshing beverage with a variety of beneficial micronutrients. The presence of heavy metals in beverages is a major concern for public health due to their biotoxic effects. In this work, the heavy metal removal potential of live tea fungus from Kombucha drink is studied. The effect of four influencing parameters on biosorption of metals, including initial tea fungus dosage, tea content, sugar content and water hardness, was investigated and optimized by central composite design (CCD) under response surface methodology (RSM). The analysis of variance (ANOVA) of quadratic models demonstrated that all models were statistically significant (p-value

基于中心复合设计的康普茶饮料中茶菌对重金属的生物吸附研究

摘要 红茶菌是用茶菌发酵加糖茶而得的饮料。茶菌将加糖的茶转化为含有多种有益微量营养素的提神饮料。由于重金属的生物毒性作用，饮料中重金属的存在是公共卫生的一个主要问题。在这项工作中，研究了康普茶饮料中活茶菌的重金属去除潜力。在响应面法（RSM）下，通过中心复合设计（CCD）研究和优化四个影响金属生物吸附的参数，包括初始茶菌剂量、茶叶含量、糖含量和水硬度。二次模型的方差分析 (ANOVA) 表明所有模型都具有统计显着性（p 值
