Abstract

This work demonstrates the applicability of a novel bubble-free membrane bioreactor for cultivation of methanotrophic bacteria for single cell protein production. The methane and oxygen supply were optimized, so they were in contact only in the liquid phase thereby avoiding the creation of explosive atmospheres. After optimization of gas supply, the biomass accumulated protein up to 51 % of its dry weight. The microbial protein contained most of the essential amino acids needed to serve as animal feed.
