Abstract

Anaerobic batch experimentswere carried out to examine the effect of supplementation of mixed culture bacteria with Carica papayaas enzymes for enhancement of hydrogen yield from degradation of glucose, protein, and lipids. The results showed that hydrogen yield (HY) based on protein and lipids degradation increased from 52.2 ± 7.5 to 130.6 ± 8.5 ml/g_protein, and from 43.0 ± 5.3 to 64.8 ± 3.1 ml/g_lipid respectively with addition of Carica papayaas enzymes source. This corresponded to substrate degradation efficiency of 51.3 ± 4.4% for protein and 33.7 ± 2.6% for lipids. However, the hydrogen yield and degradation efficiency of glucose was slightly improved by addition of Carica papayaas enzymes.
