acidogenesis(bio.) During acidogenesis the hydrolysis products which are relatively small, soluble compounds are diffused inside the bacterial cells through the cell membrane and then are either fermented or anaerobically oxidized. These processes occur by a complex consortium of hydrolytic and non-hydrolytic microorganisms which are the source of energy for the acidifying population. | |

ácidos grasos volátiles (AGV)Se trata de ácidos producidos por microbios en el ensilaje de azúcar y otras fuentes de carbohidratos. Por definición, son volátiles, lo que significa que se volatilizarán en el aire, en función de la temperatura. Son el primer producto de la degradación de digestión anaeróbica antes de la generación de metano. | |
