Abstract
This study was carried out to determine the
microbiological, proximate and elemental analyses of
maize-, millet- and sorghum-based Ogi in Ondo State,
Nigeria. Samples were monitored at points of preparation
from 0 to 96 hours of fermentation. Selected dilutions were
inoculated by spread-plate method on appropriate medium
for isolation of aerobic bacteria, staphylococci,
enterobacteria, lactic acid bacteria (LAB) and fungi.
Further identification was done by API 50 CHL, API 50
CHB and API 32 ID kits for LAB, aerobic bacteria and
fungi, respectively. Proximate and mineral compositions
were in accordance to standard procedures. One-sample ttest,
paired-wise sample t-test and Analysis of Variance
were used to analyze data. The microbial load gradually
increased from 0 hour and attained optimum at 24 – 48
hours of fermentation, before declining at 72 to 96
hours. LAB were persistent and most predominant.
Twenty-four bacterial species were isolated. Occurrence of
Lactobacillus plantarum (10.3%) was highest while Mucor
mucedo (0.86%) was lowest. There were no significant
differences in the microbial loads, proximate and elemental
compositions of products.Thisstudy revealed the
distribution of fermentative microorganisms and few
contaminants which were not directly associated with
fermentation process. The study also showed significantly
acceptable proximate and elemental compositions of the
products.
