Biodegradation of ochratoxin A by Pediococcus parvulus isolated from Douro wines

“…Specifically, P. parvulus strains were identified to be able to degrade OTA. This species is a Gram-positive and catalase negative LAB from the Lactobacillaceae family (Gunther et al, 1962). P. parvulus is a facultative anaerobe cocci that is strictly homofermentative and forms pares or tetrads.…”
