Crescimento De Bactérias Ruminais Em Função Da Concentração De Substrato Energético Em Meio De Cultura

Abstract

Most feedstuffs are composed of large relatively insoluble and sometimes complex polymers. These polymers must be degraded to low-molecular-weight substances by microbial extra cellular enzymes before they can be used. Extra cellular enzymes can be secreted out into cell-free rumen fluid, but much of the activity remains cell-associated (Pettipher &

Activation of inoculum microorganism from dairy cattle feces

“…In the microbial activation process, the microbial growth was affected by incubation time, substrate concentration and culture for medium acidification and became stabilized when it reached a fermentation time of 6 h and a concentration of sucrose of 6 g L -1 [5]. The purpose of this research was to produce a starter inoculum consortium for the selected biogas microorganisms that can be used for processing lignite coal waste.…”
