Abstract

See full text

Method for simultaneous selection and maintenance of a selected microbial consortium for polyhydroxyalkanoates (PHA) production in only one step, said microbial consortium being fed with at least one readily biodegradable carbon substrate, comprising a first step of aerobic cultivation of said microbial consortium in a mixed biological reactor. According to the invention, the specific cell growth rate μl of said microbial consortium is fixed at a target value, in said first step of aerobic cultivation and in that said first step of aerobic cultivation is performed under nutrient limitation such as the readily biodegradable carbon substrate uptake rate qS1 unbalanced with said fixed specific cell growth rate μ1.
