Production of the mycotoxins fusaproliferin and beauvericin by South African isolates in the Fusarium section Liseola.

The production fo fusaproliferin and beauvericin (BEA), a mycotoxin recently reported to co-occur with fusaproliferin in Fusarium infected corn by South African isolates in the Fusarium seciton Liseola, was investigated.  Five isolates each of  F.  verticillioides, F. proliferatum, F. subglutians and F. globosum were cultured on corn kenels.  Fusaproliferin was produced by four each of F. proliferatum and f. subglutians isolates. BEA was produced by four of the F. proliferatum strains and three of the F. subglutians strains. F. verticillioides failed to produce significant levels of either metabolite. F. globosum was a weak producer ofboth.  Of the four species investigated, fumonisins were produced by all except F. subglutians, which in turn was the only species whose isolates produced moniliformin.  Analysis of visibly Fusarium infected home-grown corn collected int Transkei region of the Eastern Cape Province of South Africa showed that 9/10 samples contained low levels of fusaproliferin (up to 62 ug/kg), whereas all ten samples showed BEA contamination ranging from 8 to 1734 mg/kg.
