We’ve launched a new process to transform biomass green algae raw materrials contain less lignin into fermentable sugars to create alcohol. This process has many advantages over the production process of biofuels from lignocellulosic materials normally. Through research, we have found the optimal conditions for the pretreatment process green al...
