Enhanced production of volatile fatty acids form waste algae in Taihu Lake under alkaline condition
碱性条件促进太湖蓝藻厌氧发酵产挥发性脂肪酸

Batch experiments were carried out to investigate the effect of pH value(pH 5,pH 7,pH 9) on the VFAs production through anaerobic digestion of algae waste from Taihu Lake.The VFAs composition and degradation rate of organic matters were also evaluated.The results show that when pH at 9,the VFAs yield can reach up to 0.274 g VFAs/g VS,and the degradation rate of VS is 51.91%.Meanwhile,the degradation rate of protein,carbohydrates and lipids can reach 53.2%,30%and 40.6%,respectively.Finally,compared with the ...
