This paper summarizes the experiences in Israel and elsewhere of the biotechnological processing of organic matter: experiences that could be applied in developing countries. Emphasis is given to relatively simple technologies, and the applications include preservation of forage crops and by-products, mushroom cultivation and recovery of plant cell contents. These technologies might increase milk and meat production in developing countries and increase the profits of the local farmers. In addition, the resulting utilization of crop residues and by-products might help to decrease environmental pollution.
