Abstract

Four bacterial strains (Bacillus amyloliquefaciens BICS 08b, B. subtilis AUMC 63,
Lactococcus lactis BICS 081b and Pseudomonas fluorescence BICS 0149b) were tested for their ability to inhibit both growth and mycotoxins production by different 11 toxigenic fungi; five local isolates from different Egyptian food sources and six standard strains obtained from CBS, Central Bureau voor Schimmelcultures, Holland. Pseudomonas fluorescence BICS 0149b completely inhibited growth of nine fungi and completely inhibited toxin production by the 11 tested fungi. Bacillus subtilis AUMC 63 reduced fungal growth of the 11 fungal isolates under study by 40-100%, and reduced their toxins formation by 20- 100%. Lactococcus lactis BICS 081b highly reduced both fungal growth and mycotoxins production by 76-100% and 60-100%, respectively. Bacillus amyloliquefaciens BICS 08b completely inhibited toxins formation by almost fungi while it was not highly affected their growth. From this result, some bacterial strains may be successfully used as a biological control agent of food contamination with molds and mycotoxins
