Identification and screening of Penicillium isolates from shelled corn for production of mycotoxins

Garcia R.P., . (1984) Identification and screening of Penicillium isolates from shelled corn for production of mycotoxins. In: Seminar on Health and Ecology in Grains Post-Harvest Technology, 21-24 Aug 1984, Kuala Lumpur (Malaysia).

Field Penicillia identified were P. oxalicum (7.4%) and P. funiculosum (6.6%) and P. palitans (3.3%). P. variabile (4%) was physiologically classified as an intermediate group. Field Penicillia grew fastest at 30 deg C whereas storage Penicilla grew fastest at 24 deg C. Growth at 36-37 deg C (Field Penicillia) and 4 deg C (storage Penicillia) clearly distinguished one group from the other. Penicillium spp. were screened for production of 6 mycotoxins (citrinin cyclopiazonic acid ochratoxin patulin penicillic acid and xanthomegnin). The number of positive/total tested were 0/20 citrinin 0/496 cyclopiazonic acid 0/496 ochratoxin 0/158 patulin 3/50 penicillic acid and 11/87 xanthomegnin. Only three isolates out of twenty P. cyclopium isolates and eleven out of twenty nine P. viridicatum isolates were positive for penicillic acid and xanthomegnin respectively

Abstract

Field Penicillia identified were P. oxalicum (7.4%) and P. funiculosum (6.6%) and P. palitans (3.3%). P. variabile (4%) was physiologically classified as an intermediate group. Field Penicillia grew fastest at 30 deg C whereas storage Penicilla grew fastest at 24 deg C. Growth at 36-37 deg C (Field Penicillia) and 4 deg C (storage Penicillia) clearly distinguished one group from the other. Penicillium spp. were screened for production of 6 mycotoxins (citrinin cyclopiazonic acid ochratoxin patulin penicillic acid and xanthomegnin). The number of positive/total tested were 0/20 citrinin 0/496 cyclopiazonic acid 0/496 ochratoxin 0/158 patulin 3/50 penicillic acid and 11/87 xanthomegnin. Only three isolates out of twenty P. cyclopium isolates and eleven out of twenty nine P. viridicatum isolates were positive for penicillic acid and xanthomegnin respectively
