El rol de la respiración aeróbica en el ciclo de vida de Escherichia coli
... Our experiments support the idea that the E. coli population multiply in fecal matter in the presence of oxygen, which may increase the chances of E. coli to colonize new hosts. The approximate increase in colonies (at least 10 fold) suggests that aerobic replication in fecal matter is a critical pa ...
