摘要
本研究以紫色马勃为试验对象,以孔雀石绿染料为降解基质,从菌体平板降解、发酵液培养时间(4、5和6 d)、降解处理温度(22、26、30和34℃)及染料浓度(50、100、150、200、250和300 mg/L)4个方面探讨其对孔雀石绿染料的降解效果.结果表明,紫色马勃发酵液制备条件为在26℃,160 r/min振荡培养4 d;以200 mg/L孔雀石绿染料作为基质,在30℃条件下,降解24 h,此时降解率达98.34%.研究结果为孔雀石绿染料的降解研究提供参考.
Abstract
In this study,Calvatia lilacina was selected as the test object,malachite green dyes were used as the degradation substrate,and the degradation effect of the Calvatia lilacina on malachite green dyes was discussed in 4 aspects:bacterial plate degradation,culture time(4,5,and 6 d),degradation temperature(22,26,30,and 34℃),and dye concentration(50,100,150,200,250,and 300 mg/L).The results showed that Calvatia lilacina fermentation liquid was prepared under the condition of oscillating at 26℃,160 r/min for 4 days.Using 200 mg/L malachite green dyes as the substrate,the degradation rate reached 98.34%at 30℃for 24 h.The results provide references for the degradation of malachite green dyes.
