Abstract
Biologically pure cultures of Bacillus subtilis Maseca-1 strain were isolated from the pericarp of nixtamalized corn. The Bacillus Maseca-1 strain was characterized and found to produce peptides and/or other compounds that have antimicrobial activity. An extract prepared from the Bacillus Maseca-1 strain is active against microorganisms such as bacteria and mold and may be used as an agent to inhibit the growth of undesirable microorganisms and thereby prevent spoilage and extend the shelf life in foods.
