Abstract

Rain Tree (Pithecolobium saman Bentham) kernels, rich in fermentable sugars were employed for methane generation through anaerobic digestion using 20-• biodigestors under a semi-continuous feeding mode. A loading rate of 45 g/I/d resulted in the accumulation of volatile fatty acids (1725 rag//) which led to souring of the digestor. To avoid the excessive production of volatile fatty acids by the non-methanogenic microorganisms and to stabilize the anaerobic digestion process, penicillin was added and a gas yield of 0.49 m3/kg VS added with an average methane yield of 0.21 m3/kg VS added was obtained.
