Lactobacillus casei CRL 431 and Lactobacillus rhamnosus CRL 1224 as biological controls for Aspergillus flavus strains. Aspergillus flavus populations are diverse and composed of vegetative compatibility groups (VCGs), which largely restrict hyphal fusion to strains within the same VCG and thus limit genetic exchange across VCGs (Grubisha and Cotty, 2009). Genomics studies have revealed that proteins necessary for fungal development are also necessary for regulation of aflatoxin biosynthesis and that the two processes are linked (Bayram et al., 2008; Wiemann et al., 2010). If a pets food contains aflatoxins, the toxins could accumulate in the pets system as they continue to eat the same food. Aspergillus flavus and A. parasiticus produce aflatoxins that are toxic to the liver and are carcinogenic;176 e.g. Deepak Bhatnagar, Gary A. Payne, in Encyclopedia of Food Microbiology, 1999. The three former species are economically important because of their industrial applications.
