Abstract:
     The technique for culturing chlorella includes natural fermentation of acidic waste liquid after extraction of glycyrrhizic acid, diluting by 10 times with clean water, regulation of pH value to 5-7, mixing with 0.5% bone powder water, natural temp. raising to 20-40 deg.C, inoculation of seed chlorella, control of temp. and pH value, make up of CO2 and removal of excess O2. The inoculation is performed in a full-enclosed environment. It features high quality of chlorella and low cost.
