GALICIA-JIMENEZ, Mónica Marcela; SANDOVAL-CASTRO, Carlos; ROJAS-HERRERA, Rafael  e  MAGANA-SEVILLA, Héctor. Bacterial chemotaxis and flavonoids: prospects for the use of probiotics. Trop. subtrop. agroecosyt [online]. 2011, vol.14, n.3, pp. 891-900. ISSN 1870-0462.

The application of different diets have focused on seeking greater production in the ruminant animal feed varies, thus affecting rumen microbial population, however, the production efficiency of ruminants has been reported inconsistently. Furthermore, studies have been conducted secondary metabolites secreted by plants and has been having a function of attractant or repellent in plant-microbe interactions. So our goal is to integrate knowledge of rumen bacteria-particle interactions of forage used for food and flavonoids as stimulants in the flagellar movement. Thus, understanding the signaling pathways used by rumen bacteria to colonize food particles and degradation. Research and implement programs using genomic tools to help us discover chemotactic genes in rumen bacteria that contribute to elucidate principles governing the communication of microbial populations, their interactions and main products of microbial metabolism, and thus could raise the handling of ruminal fermentation, creating the probiotic cultures for cattle.
