| Abstract | ||||
| The antimycotoxigenic of Brevibacterium linens (B. linens) against Aspergillus flavus (A. flavus) in solid and liquid media was studied. Aflatoxins B1, B2, G1 and G2 were detected in all tested media using TLC technique and quantitatively determined by HPLC. The obtained data revealed that B. linens reduced the growth of A. flavus when the two microorganisms were inoculated on nutrient agar medium at the same time (zero time) or when B. linens was grown for one day before A. flavus growth. While, complete inhibition of A. flavus growth was occurred in 2 and 3 days old culture of B. linens. Also, complete inhibition of aflatoxins production was occurred in B. linens culture at Zerotime and up to 3 days old. Agitation during B. linens growth on nutrient broth medium is an important factor to prevent the fungal growth and imeresed production of the antifungal compound(s). The use of 100% of B.linens culture of 3'days old as a growth medium for A. flavus inhibited the fungal growth and sporulation. The results indecated that B. linens has potential effect may be use as biological control against mold growth and mycotoxins production in foods and dairy products. | ||||
