Bioenergy production from chicken feather waste by anaerobic digestion and bioelectrochemical systems.

ABSTRACT:

Background

Poultry feather waste has a potential for bioenergy production because of its high protein content. This research explored the use of chicken feather hydrolysate for methane and hydrogen production via anaerobic digestion and bioelectrochemical systems, respectively. Solid state fermentation of chicken waste was conducted using a recombinant strain of Bacillus subtilis DB100 (p5.2).

Results

In the anaerobic digestion, feather hydrolysate produced maximally 0.67 Nm³ CH₄/kg feathers and 0.85 mmol H₂/day.L concomitant to COD removal of 86% and 93%, respectively. The bioelectrochemical systems used were microbial fuel and electrolysis cells. In the first using a microbial fuel cell, feather hydrolysate produced electricity with a maxim
