I Firmicutes sono un phylum di batteri gram positivi.

Which bacteria are Firmicutes?

The Firmicutes phylum is composed of more than 200 different genera such as Lactobacillus, Bacillus, Clostridium, Enterococcus, and Ruminicoccus. Clostridium genera represent 95% of the Firmicutes phyla. Bacteroidetes consists of predominant genera such as Bacteroides and Prevotella.

How do I reduce Bacteroides in my gut?

Digestible carbohydrates from fruits (e.g., glucose, sucrose, and fructose) have been shown to reduce Bacteroides and Clostridia (54). Non-digestible carbohydrates most consistently increase lactic acid bacteria, Ruminococcus, E. rectale, and Roseburia, and reduce Clostridium and Enterococcus species (54).
