Abstract

This paper describes the key role of lipids on fungal growth and of lipoperoxidation on the output of aflatoxin biosynthesis both ‘in vitro’ and ‘in vivo’. ‘In vitro’ BHA, BHT and cysteamine, depending their concentration, are capable of reducing or blocking aflatoxin output induced by lipoperoxides or halomethanes in cultures ofAspergillus flavus orA. parasiticus without affecting fungal growth. ‘In vivo’ BHA and BHT significantly reduced aflatoxin production on wheat, maize and sunflower inoculated with aflatoxigenicAspergilli essentially by preventing fungal growth. ‘In vivo’ the seeds surface lipids represent a very important carbon source for fungal growth.
