Abstract:
Aflatoxins are produced by Aspergillus flavus and Aspergillus parasiticus. These are
secondary metabolites toxic in nature and belong to the family mycotoxins. AFB1 is the most
potent carcinogen which gave serious effects on health and economy of developing country.
There are physical and chemical methods utilized to degrade aflatoxins but they are highly
persistent and show high resistance to degradation such methods also deteriorate quality of
agricultural feeds. It is difficult to remove aflatoxin from food chain. Utilization of modern
degradation methods which uses biological microorganisms to degrade and reduce aflatoxin
to a less toxic form. Degradation by bacteria is an affective mode of approach to tackle
aflatoxins which is feasible and cost effective. This study includes isolation of bacteria from
field soil and their characterization.
Keywords: Aflatoxins, bacteria, biological degradation and enzymes.
