摘要

PURPOSE: Bacillus amyloliquefaciens B4-4 having enzyme activity and antibacterial activity is provided to suppress food poisoning bacteria and various bacteria. CONSTITUTION: Bacillus amyloliquefaciens B4-4 produces cellulase, amylase, protease, and zylanase and has antibacterial activity against Candida, Listeria, Salmonella, Staphylococcus, Bacillus cereus food poisoning bacteria, and E. coli. A medium(R2A) for isolating the strain contains 0.5g of yeast extract, 0.5g of proteose peptone, 0.5g of casamino acids, 0.5g of dextrose, 0.5g of soluble starch, 0.3g of sodium pyruvate, 0.3g of dipotassium phosphate, 0.05g of magnesium sulfate, and 1000 ml of distilled water.
