Effects of different enzymes on carbohydrates extractionfrom microalgal biomass for bioethanol production

Enzymatic hydrolysis of cellulose and starch are usually performed by cellulase and amylases enzymes, respectively. Although the enzymatic hydrolysis of starch and cellulosic material has been extensively reported, it is scarcely investigated on microalgal biomass. Especially, effects of addition of various enzymes in enzymatic hydrolysis of non- sterile, mixed microalgae culture has not been reported.The present work deals carbohydrates extraction from the mixed microalgae culture using different enzymes for bioethanol production. Among the all enzymatic treatments tested, the highest sugar yield of 99% was obtained with sequent addition of cellulase, α-amylase, and glucoamylase
