Abstract: | Valuable co-products derived from fractionation of alfalfa herbage give the resulting fibrous fraction an economic advantage
as a feed stock for ethanol or other organic products. Alfalfa fiber was saccharified and fermented with or without a liquid
hot water (LHW) pretreatment. The LHW pretreatment hydrolyzed approximately 60% of the original fiber, yielding a high cellulose
residue and aliquid extract. These yielded predominantly hexoses and pentoses, respectively, after enzymatic saccharification.
Yields of ethanol and lactic acid resulting from fermentations are given. |
