Experimental short time production of aflatoxins by Aspergillus parasiticus in mixed feeds as related to various moisture contents
Experimental short time production of aflatoxins in mixed feeds at 22, 28 and 37 degrees C as related to various moisture contents was studied. Growth of Aspergillus parasiticus was not observed in the meals with a moisture content ranging around 15% (22, 28 and 37 degrees C); the lowest quantifiable total aflatoxins at the fourth day was detected at 22 degrees C with 19.4% of moisture content; the higher total quantity of aflatoxins (113 mg/kg) was produced at 28 degrees C with 29.3% of moisture content. The ratio aflatoxin B1/aflatoxin G1 increased as the temperature raised… Leer más

Isolation de micro organismes du genre Listeria à partir de lait cru destiné à la consommation humaine
Canadian Journal Of Microbiology 31:938 941.
Refrigerated mixtures of raw milk provided by a dairy which was supplied by farms from west and central Spain were tested for the presence of Listeria microorganisms. A total of 95 samples were taken at regular intervals over a 16-month period. Listeria grayi was isolated from 89.5% of the samples, Listeria monocytogenes s. str. from 45.3%, Listeria innocua from 15.8%, Listeria welshimeri from 3.1%, and Listeria seeligeri from 1.05%. Listeria ivanovii, Listeria murrayi, and Listeria denitrificans were not isolated.[Translated by the journal]… Leer más
