Degradation of suspended proteins in an anaerobic rotating bed contactor

A protein rich suspension, obtained from spent grains, was digested in an anaerobic rotating bed contactor (AnRBC) at 37 degree C, pH = 7 and a hydrolic retention time of 1 hr. The hydrolysis and acidification of the suspension was about 50% on organic carbon basis at reactor loads of 2.5 kg TOC/m3....

Zusammenfassung:	A protein rich suspension, obtained from spent grains, was digested in an anaerobic rotating bed contactor (AnRBC) at 37 degree C, pH = 7 and a hydrolic retention time of 1 hr. The hydrolysis and acidification of the suspension was about 50% on organic carbon basis at reactor loads of 2.5 kg TOC/m3.d (7.5 kg COD/m3.d). A further increase of the conversion rate seems quite possible with an improved reactor configuration.
