For each species, they estimated maximum growth rates, optimal growth temperatures, and the temperature ranges within which the species could grow. (sciencemag.org)
Members of this family are distinguished from the other family (Desulfurococcaceae) in the order Desulfurococcales by having an optimal growth temperature above 100 °C, rather than below 100 °C. (eol.org)
