Knowledge of the nitrogen compounds utilized for growth of ruminal cellulolytic bacteria is of considerable importance to an understanding of the nitrogen economy of ruminants and of factors affecting ruminal cellulose digestion. Work with mixed cultures of bacteria from the rumen has shown that cellulose digestion occurs with ammonia or urea, which rapidly yields ammonia, as the sole source of...
The key material for bioethanol production is cellulose, which is one of the main components of the plant cell wall. Enzymatic depolymerization of cellulose is an essential step in bioethanol production, and can be accomplished by fungal and bacterial cellulases. Most of the biochemically characterized bacterial cellulases come from only a few cellulose-degrading bacteria, thus limiting our kno...
Locusts are able to digest the cellulose of Gramineae plants, resulting in their being considered as major crop pests. To illustrate the mechanism involved in cellulose digestion, the cellulolytic activity and zymography in the gut contents of 16 locust species were determined using carboxymethyl cellulose (CMC) as substrate. The diversity of gut symbiotic bacteria was studied using denaturing ...
BACKGROUND The use of lignocellulosic materials for second generation ethanol production would give several advantages such as minimizing the conflict between land use for food and fuel production, providing less expensive raw materials than conventional agricultural feedstock, allowing lower greenhouse gas emissions than those of first generation ethanol. However, cellulosic biofuels are not p...
