[Toxinogenic moulds in silage. V. - Production of byssochlamic acid in liquid medium with by Byssochlamys nivea Westling, Byssochlamys fulva Olliver and Smith and Paecilomyces varioti Bainier isolated in forages (author's transl)].
The toxinogenesis of 10 strains of Byssochlamys nivea, 4 of Byssochlamys fulva and 8 of Paecilomyces varioti is studied in Czapek's enriched liquid medium (8 p. 1000 glucose + 2p. 1000 yeast extract) at 26 degrees C. 60 p. 100 of Byssochlamys nivea filtrates, 100 p. 100 of Byssochlamys fulva filtrates and 37 p. 100 of Paecilomyces varioti filtrates contain byssochlamic acid after 60 days of culture at 26 degrees C. The concentrations observed vary from 40 to 540 p.p.m. In these moulds, patuline-production ability has also been tested (Escoula, 1975 c). There seems to be no relation between the production of patuline and of byssochlamic acid in these three species.
