In the present study we have evaluated the antibacterial effect of the extracts of two widely used spices in India, Cinnamomum verum and Syzygium aromaticum against two bacterial strains of food borne pathogens, Pseudomonas lundensis and Bacillus cereus, and two fungal strains of food borne pathogens, Aspergillus niger and Aspergillus flavus.

Aspergillus flavus is well known in food safety circles because some strains produce the acutely poisonous aflatoxin mycotoxin, but none of the 25 strains of Aspergillus flavus isolated from these black teas were found to be mycotoxin synthesisers.
One of these, the fungus Aspergillus flavus, can produce a potentially dangerous mycotoxin called aflatoxin.

As seen from the figure, the frontal face sample shows heavy colonies of Aspergillus fungi of different species: Aspergillus niger, Aspergillus flavus, and Aspergillus terreus.
Researchers say that a natural compound, an antioxidant known as caffeic acid, prevents Aspergillus flavus fungus from producing aflatoxins when a tree nut produces an oxidant to fight off this invader.
