2010 journal article

A comparison of the autohydrolysis and ammonia fiber explosion (AFEX) pretreatments on the subsequent enzymatic hydrolysis of coastal Bermuda grass

Bioresource Technology, 101(14), 5449–5458.

By: J. Lee n, H. Jameel n & R. Venditti n

author keywords: Autohydrolysis; Ammonia fiber explosion; Coastal Bermuda grass; Enzymatic hydrolysis; Ethanol
