Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Aflatoxin contamination in food and feed is a seriously problem threaten to human and animal´s health. In this paper, a novel bacterial strain, Hitwh-B5 was screened with strong inhibition activity against aflatoxin production by Aspergillus parasiticus. Hitwh-B5 strain was identified as Bacillus subtilis by phenotypic, biochemical characterizations. The cell-free supernatant fluids (CFSF) of Hitwh-B5 collected daily during a 12 day incubation period were tested and showed active against NA accumulation and hyphal growth of Aspergillus parasiticus NFRI-95 strain. The active metabolites in CFSF were heat-stable, acidand alkaline-stable, and resistant to enzymatic cleavage. Therefore, the study highlights the potential application of B. subtilis Hitwh-B5 or its metabolites in biocontrol of aflatoxin-producing in food and feed storage.
