Simultaneous Saccharification andFermentation : 동시당화발효법) 은 말 그대로 당화와 발효를 동시에 행하는 것으로 전체적인 효율개선을 노린 기술이다.
전처리가 끝난 목질계 바이오매스로부터 연료용 에탄올을 생산하는 반응 메커니즘은 크게 두 가지로 당화와 발효라 할 수 있다.

and it can be used not only for biodiesel production but also for bioethanol production. Bioethanol can be produced by starch from algae through hydrolyze, pre-treatment andfermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and water, those free complex carbohydrates turned into fermentable sources through pre-treatment process - saccharification. Then, it ca
and 100 degrees centigrade to hydrolyze the starch into solution.
Once crops have been harvested, the cellulosic parts
must be removed and the starches collected.
In the case of corn, this entails separating the leaves,
stalk, and cob so that only the grains remain.
The corn grains will be processed into glucose, which will ferment with the help of yeast and amylase, a specified en
and is expected to reach 100 billion liters in 2015. Less than 4% of the ethanol is produced synthetically from oil, while the rest is produced by fermentation from bioresources. Ethanol is now produced from two major groups of bioresources : sugar substances and starchy materials. There is a competition between these two feedstocks for fuel ethanol production. While sugar substances were the fee
