Abstract
Abstract A newly discoverd microorganism having characteristics of an Arthrobacter and having the ability to utilize peanut hull lignin as a sole source of carbon is disclosed. Peanut hulls have a higher lignin content than hardwoods and softwoods. The newly discovered microorganism makes the biodegradation of peanut hulls and other similar lignin containing biological waste products commercially feasible. Specifically, a process for converting peanut hulls and other similar lignin containing biological waste products to animal feed is disclosed.
