Abstract:

Butyric acid oriented production via anaerobic fermentation is a desirable pathway to the recycling treatment of blue-green algae.In the study,four different pretreatment methods,namely acid,alkaline,heat and microwave were used to enhance the fermentation.The content of butyric acid and total organic acids produced from pretreated blue-green algae was evaluated.The results indicated that all pretreatments enhanced the t the production of butyric acid and total organic acids.Among of them,alkaline pretreatment at pH 10 exhibited the highest production of butyric acid and total organic acids from the blue-green algae feedstock,the value achieved at 4390 mg/L and 5962 mg/L,respectively,which both doubled as compared to that before pretreatment.
