Abstract
Anaerobic digestion (AD) is an important process for generating third-generation fuel in the form of methane from a variety of organic wastes. Efficiency of AD is dependent on inhibitory effect exerted by the substrate on methanogenic pathway. Here we assess the potential of utilizing lipid-rich waste as a suitable substrate for methane production. Anaerobic digestion of lipids leads to production of long-chain fatty acids (LCFAs) which are known to inhibit acetoclastic methanogens. The problems faced during AD of lipid-rich waste, strategies for overcoming the problems, and application of genomic tools for characterization of microbial community involved in biomethanation of this substrate are also discussed.
