PIGMENT PRODUCTION IN BACTEROIDES [PDF]
Journal of Medical Microbiology, 1969 Summary Chromogenesis by three members of the genus Bacteroides was studied. The species investigated were: Bacteroides melaninogenicus, B. fragilis and B. necrophorus. All were capable of pigment production, but each species required a different set of factors for chromogenesis. All needed cysteine and ferrous sulphate.

Hadza Prevotella require diet-derived microbiota-accessible carbohydrates to persist in mice
Cell Reports, 2023 Summary: Industrialization has transformed the gut microbiota, reducing the prevalence of Prevotella relative to Bacteroides. Here, we isolate Bacteroides and Prevotella strains from the microbiota of Hadza hunter-gatherers in Tanzania, a population with
