Dual species biofilms are enhanced by metabolite cross-feeding

Debra N Brunson et al. Trends Microbiol. 2022 Sep.

Abstract

Enterococcus faecalis and Staphylococcus aureus are frequently co-isolated from biofilm-associated infections. A new study by Ch'ng et al. revealed that S. aureus-released heme feeds E. faecalis respiration, augmenting E. faecalis growth and overall biofilm biomass. Their finding further supports the theory that metabolite cross-feeding is a critical aspect shaping polymicrobial biofilm interactions.
