Wavelength-dependent degradation of ochratoxin and citrinin by light in vitro and in vivo and its implications on Penicillium.
Toxins (Basel.) 4(12) , 1535-51, (2012) It has previously been shown that the biosynthesis of the mycotoxins ochratoxin A and B and of citrinin by Penicillium is regulated by light. However, not only the biosynthesis of these mycotoxins, bu... |
