SSF is a process in which the production of ethanol from cellulosic materials is achieved by utilizing cellulose, cellulase, ethanol-producing microbes and nutrients in the same reactor. This process is desirable because the continuous removal of sugars by fermentative organisms alleviates end-product inhibition of enzyme hydrolysis of cellulose. The process is also simplified because only one reactor is used. The SSF process for ethanol production from cellulosic materials was reported by Blotkamp et al. [65] and was later tested on a pilot scale (for detail, see [66]).

The sonicated cell fraction from cellulose enrichment cultures was used to study enzymic hydrolysis of cellulose in alder sawdust subjected to gamma irradiation. 

A comparison (15) of activities of acid and enzyme catalysts on three cellulosic substrates at 50°C. shows that 100,000 times as much acid is required to bring about the same degree of hydrolysis. At the molecular level the difference is further increased because of the disparity in mol. wt. [(HC1-36, cellulase 63,000 ( 23)], so that approximately 108 HC1 molecules are required to perform the work of a single enzyme under certain conditions. This is a point strongly in favor of enzyme hydrolysis of cellulose.
