Rhizopus Mycotoxins

Rhizopus microsporus strains have also been described as a source of food mycotoxins. Rhizonins, such as 93 (Scheme 11), which were the first-described toxins from zygomycetes, are strongly hepatotoxic nonribosomal peptides isolated from moldy peanuts in Mozambique. Examination for the presence of bacteria again showed that a Burkholderia sp. endosymhiont is the true biosynthetic source.As with the rhizoxin (28) producer, the establishment of a pure symbiont culture was successful.
