Introduction
Cassava (Manihot esculenta Crantz) is a major source
of dietary energy for humans and domestic animals in
many tropical countries (Tewe, 1992). It is a perennial
crop that produces reasonably well under critical
conditions of climate and soil, including drought and
infertile soils, and is able to recover from disease and
pest attacks (El-Sharkawy, 1993). However, a limiting
characteristic for the consumption of cassava is its
content of cyanogenic glycosides (linamarin, lotaustralin
and 2-((6-O-(b-D-apiofuranosyl)-b-D-glucopyranosyl)oxy)-
