Mycotoxin-producing strains of Penicillium viridicatum: classification into subgroups.
Fifty-two isolates of Penicillium viridicatum Westling were divided into three groups based on ability to produce ochratoxin and/or citrinin, color, growth rate, type of growth, odor, and isolation source. Members of group I resemble one of the representative strains of P. viridicatum described in the literature; those belonging to group II differ from group I strains in several characteristics...
متن کاملOCCURRENCE OF A MYCOTOXIN, OCHRATOXIN A, IN WHEAT AND ISOLATION OF OCHRATOXIN A AND CITRININ PRODUCING STRAINS OF PENICILLIUM VIRIDICATUM Ochratoxin A is a metabolite of Aspergillus ochraceus
Ochratoxin A is a metabolite of Aspergillus ochraceus Wilh. (5) and of Penicillium viridicatum Westling (8). It is highly toxic to rats and ducklings and produces liver and kidney damage (6). Both A. ochraceus and P. viridicatum have been isolated from stored grain, and ochratoxin A itself was recently found in corn (7). The presence of this toxin in rolled wheat used as livestock feed is repor...
متن کاملPenicillium viridicatum, Penicillium verrucosum, and production of ochratoxin A.
The taxonomy of the important mycotoxigenic species Penicillium viridicatum and P. verrucosum was reviewed to clarify disagreements relating to the three P. viridicatum groups erected by Ciegler and coworkers (A. Ciegler, D. I. Fennell, G. A. Sansing, R. W. Detroy, and G. A. Bennett, Appl. Microbiol. 26:271-278, 1973) and the mycotoxins produced by them. Cultures derived from the types of these...
متن کاملTremorgenic mycotoxin from Penicillium paraherquei.
A tremorgenic mycotoxin was isolated from Penicillium paraherquei Abe ex G. Smith and identified as verruculogen. It was produced at the rate of approximately 1 mg/g of the dried fungal mycelium cultured on peptone-enriched Czapek-Dox medium at 28 degrees C.
متن کاملA Comparison of Penicillin-producing Strains of Penicillium notatum-chrysogenum.
Sampling and storage. The fermentations were conducted in the 100-gallon tanks described by Stefaniak et al. (1946). Samples were removed periodically into 500-ml flasks and ifitered. A 0.5-ml filtered sample was immediately diluted for penicillin assay by addition to previously chilled phosphate buffer in volumetric flasks (4.0 g KH2P04 and 1.0 g K2HPO4 per 500 ml solution in distilled water; ...
