摘要: 本文研究了云芝菌株在模拟废水中生长,获得对废水较高的漂白效果以及最大菌丝体产量的培养基成份为:模拟废水培养基中初始外加碳源-葡萄糖添加量为1%、氮浓度范围是6~12mmol/L、CaCl2浓度为0.05mol/L、RS为消泡剂。利用均匀实验设计结果表明氮浓度是影响云芝对废水脱色率的主要因素,氮源与VB1含量的交互作用项对生物量的影响最为显著。

Abstract: Colorants biodegradation and growing condition of the Polystictus versicolor cultured with simulation effluent were investigated. The results showed that the optimum concentration of initial glucose was 1%, concentration of N was 6~ 12mmol/L and concentration of CaCl 2 was 0.05mol/L, while the appropriate antifoaming agent was RS. The results of even design displayed that the concentration of N was the main influencing factor of colorants biodegradation; and the interaction of concentration of N and biotin became the main influencing factor of biomass.
