title: [Toxinogenic moulds in silage. VI - Effect of propionic and formic acids on the production of patulin and of byssochlamic acid by Byssochlamys nivea Westling (author's transl)].
abstract: A strain of Byssochlamys nivea is cultivated for 5 months at 26 degrees C on kernels of wet corn previously treated with three doses of formic acid (1, 5, 3, 6 p.1000) and three doses of propionic acid (0.5, 1, 2 p. 100). As related to the control lot, the addition of these acid results, in the first two doses, in a decrease and slowing-down of the growth of the mould and the production of its two mycotoxins (patulin and byssochlamic acid). In the presence of 0.6 p. 1000 of formic acid, and especially with 2 p. 100 of propionic acid, Byssochlamys does not develop during the trial period. This inhibition may be annulled when the mould is put on a medium (Czapek) containing no acid.
