| toxicity and trichothecene production by fusarium acuminatum subsp. acuminatum and fusarium acuminatum subsp. armeniacum. | the toxicity of cultures of fusarium acuminatum subsp. acuminatum and fusarium acuminatum subsp. armeniacum grown on weet-bix medium was assessed using a chick bioassay. thirty-nine of 45 cultures of f. a. armeniacum tested produced at least 50% mortality in the chick bioassay. in contrast, of the 26 cultures of f. a. acuminatum tested, only nine produced at least 50% mortality. selected extracts of both subspecies were analyzed by gas chromatography after clean-up and hydrolysis for the four ma ... | 1993 | 8167939 |
