Phylogenetic analyses of aligned DNA sequences obtained via the polymerase chain reaction from the nuclear 28S ribosomal DNA, nuclear ribosomal internal transcribed spacer region, and beta-tubulin gene exons and introns indicate that the Quorn fungus is Fusarium venenatum rather than F. graminearum as previously reported. Analysis of mycotoxins from rice cultures inoculated with Quorn strain NRRL 25416 revealed that four type A trichothecenes are produced, but at low levels relative to strain NRRL 22198 of F. venenatum. No trichothecenes, however, were detected from the analysis of three commercial Quorn products marketed for human consumption in England.
