Abstract
Pressed and wilted samples of Sorghum bicolor cv. Rio were ensiled for periods of up to 155 days. Silage pH levels declined to 3.9-4.0 within a few days. A kinetic study of the biochemical changes which occurred during ensiling showed that total sugar content in wilted sorghum silage was 250-300 g/kg DM compared with 100 g/kg DM for pressed silage. The acidic environment produced by ensiling also served as a pretreatment for enhancing the enzymatic hydrolysis of the lignocellulosic component of S. bicolor. The reducing sugar yield from enzymatic hydrolysis of pressed silage increased from 137 g at the start of ensiling to 232 g/kg DM one month after inoculation. The corresponding increase for wilted silage was from 101 to 164 g/kg DM. Both Saccharomyces uvarum and Clostridium acetobutylicum were able to ferment a medium constituted from pressed S. bicolor juice and the solution resulting from enzymatic hydrolysis of S. bicolor silage
