✦ Synopsis

In stationary cultures the spore number in inoculum was found to have an inverse relationship with the yield of aflatoxin, a secondary metabolite of Aspergillus fzavus and A. parasiticus.' However, in shake cultures, the mold grew in the form of pellets and the experimental yields of the metabolite were found to vary considerably depending on the size of the pellets. Earlier studies using 20-L fermentors suggested the use of small pellets for better yields, without studying the effect in detail.' Spore concentration in inoculum is recognized to influence the characteristics of pellet^.^ This communication therefore reports the relationship between spore number, pellet size, and yield of the toxin.
