Peptone was produced from soya beans and African locust beans. The produced peptones were evaluated as component of microbiological media for the growth of some bacteria and compared with some commercial peptones. Some of the tested bacteria are Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis. The soya beans and African locust beans peptones supported the growth of all the tested bacteria favourably well when compared to the commercial peptones. From the peptone broth cultures at absorbance 540 nm, the best growth was obtained from Escherichia coli in laboratory-produced soya beans peptone and Staphylococcus aureus in Bacto peptone (a commercial peptone). This may reduce the cost of peptone in Nigeria.

Key words: African locust beans, peptone, soya beans.
