| 摘 要： | 蓝藻厌氧发酵定向产丁酸是蓝藻资源化处置的理想方式。作者选择4种操作简单易行的预处理方法,即酸法、碱法、加热和微波法对蓝藻进行预处理,考察处理后蓝藻厌氧发酵的丁酸和有机酸产量。结果表明,各预处理方法均能不同程度地提高蓝藻厌氧发酵过程中的丁酸产量和有机酸产量。其中蓝藻经过pH 10碱性预处理后调节初始pH 5.0厌氧发酵的丁酸及有机酸产量最高,分别为4390 mg/L和5962 mg/L,比空白提高了近1倍。

| 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 pretreatm... |
