Abstract : Cellulase production from agricultural wastes has been concentrated mostly on fungi. This study was carried out
to isolate, characterize and screenbacteria isolated from corncob for cellulase production. Maize cobs were obtained from
dumping sites at Oyo town, sundried and grounded prior bacteria isolation. Pour and spread plates techniques were used for
isolation. Biochemical and physiological tests were used for bacteria identification. The identified bacteria were then
cultivated, screened and optimized for enzyme production. Nineteen isolates were identified from the corn cobs using
microscopic observation, morphological growth characteristics and biochemical tests. These include Bacillus spp(10),
Pseudomonas spp(8) and Proteus spp (1). Cellulase production occurred within the exponential growth phase of the
organism which was observed to be on day 7 using both glucose and CMC as carbon sources, respectively. The cellulase
produced by Bacillus subtilis isolated from corn cob using CMC as a carbon source could be of great importance in agro
industry in the production of economically useful animal feed.
