Lactobacillus cellobiosus is the major lactic<br />

acid bacteria (24%) followed by Lb<br />

plantarum (14%) and Pediococcus<br />

pentosaceus (12%) (Fig.2). Considering Lb<br />

fermentum and cellobiosus as belonging to a<br />

same group, the bacterial collection is<br />

dominated by Lb fermentum-like species<br />

which are heterofermentative. For some<br />

different fermented cereal-based foods, Lb<br />

plantarum dominated the bacterial population<br />

at the end of fermentation, such as in<br />

Nigerian Ogi (Akinrele, 1970), Uganda boza<br />

(Gotchva et al, 2000) and Tanzanian togwa<br />

(Mugula et al, 2003).<br />
