Build-up of symbiotic methanogenic biofilms on solid supports

Biotechnology Letters Aims and scope Submit manuscript

Abstract

Support surfaces can have selective action which determines the relative quantities of acetogens (propionate and butyrate degraders) and methanogens (acetate degraders) immobilized in a symbiotic biofilm. The preference of the bacteria for hydrophilic substrata as their immobilization supports is in the order; butyrate degraders, acetate degraders followed by propionate degraders.
