Abstract
Improvement of biogas production was realized by covalent immobilization of a methanogenic consortium onto a granulated polymeric support [poly(acrylo nitrile-acrylamide)]. The growth kinetics of the immobilized consortium was investigated during a process of vinasse methanation, and a cell concentra tion increase from 12.3 mg g(-1) support to 52.1 mg g(-1) support was estab lished. The methane yield reached 0.33 m(3) kg(-1) CODr, the maximum yield on chemical oxygen demand (COD) removal being 92%. The inhibitory effect of oxygen was reduced by immobilizing the methanogenic consortium. (C) 2001 E lsevier Science Ltd. All rights reserved.
