The ochratoxin A (OTA) polyketide synthase otapks gene has been cloned from Penicillium verrucosum. A P. verrucosum mutant in which the otapksPV gene has been interrupted cannot synthesize ochratoxin A. The protein is most similar to the citrinin polyketide synthase

By taking advantage of the intrinsic fluorescence of ochratoxin A (OTA), we present a fluorescence anisotropy approach for rapid analysis of the interactions between OTA and aptamers. The specific binding of OTA with a 36-mer aptamer can induce increased fluorescence
A reliable exposure assessment of mycotoxin contamination relies on their unambiguous identification and accurate quantification. With such purpose, a new analytical methodology was developed for evaluation of ochratoxin A (OTA) contamination in pork. Briefly OTA extraction from minced muscle samples
