conclusions antimicrobial and antitoxigenic properties of natural products need a firmly established criterion before they could be offered to application. results a significant reduction in aflatoxin production was noted which was not due to the inhibitory effect but because of antifungal property of the oil. interestingly, the oil promoted toxin production for the reasons yet to be investigat...

background: lactobacilli are known as a valuable sourceof antimicrobial compounds and have a high potential of use infood biopreservation against food related microorganisms.objectives: antimicrobial potency of 63 dairy lactobacilliisolates against four highly important food-related microorganismswere evaluated. in addition, a new way in data organization wasintroduced, which led to a more info...

Aspergillus flavus Link:Fr. may infect seed of corn, cotton, peanut, and tree nuts and contaminate them with aflatoxins, which are potent hepatoxic, carcinogenic metabolites that pose a significant health hazard (3,4). Members of Aspergillus section Flavi are widespread in crop fields, particularly in subtropical to tropical latitudes (5,11,17,19). Population biologists seek to understand the g...

The present work was carried out to study the mycobiota of cocoa beans from farm to chocolate. Four hundred and ninety-four samples were analyzed at various stages of cocoa processing: (i) primary stage at the farm (fermentation, drying, and storage), (ii) secondary stage at processing (testa, nibs, liquor, butter, cake and powder) and (iii) the final chocolate product (dark, milk, white and po...

Biosynthesis of active secondary metabolites by fungi occurs as a specific response to the different growing environments. Changes in this environment alter the chemical and biological profiles leading to metabolites diversification and consequently to novel pharmacological applications. In this work, it was studied the influence of three parameters (fermentation length, medium composition and ...
