Effect of different carbon sources on the growth of antimicrobial producing Bacillus species in ogiri-egusi sold in Ogbeta, Orie,
Artisian, Kenyatta, Enugu State were evaluated using standard microbiological and analytical methods. 12 bacteria were isolated and
identified such as Bacillus subtilis,(33.33), Bacillus pumulis (41.66), Bacillus licheniformis (25) were identified based on their colony
biochemical characteristics.The isolates of the highest occurrences is bacillus pumilus. Agar well diffusion method was used to determine
the antimicrobial activity against two pathogenic organisms, Escherichia coli, Staphylococcus aureus. Bacillus subtilis and
Bacillus pumulis, gave a zone of inhibition Escherichia coli 0.6mm and 0.8mm after 24 hours of incubation also carbon sources of 5%
and 10% sucrose, Glucose and soluble starch were used to check their different carbon sources on the isolates using the
spectrophotometer.5% had the highest optimum growth of 1.400 for glucose 1.545 for sucrose,2.376 for soluble starch which can be added
in maximum quantity to a medium to produce antibiotics.
