Abstract: A pipe joint includes a first pipe and a second pipe. The first pope has a first annular flange at one end, the first annular flange including a first end face. The second pipe has a second annular flange at one end, the second annular flange including a second end face. The first annular flange is mated to the second annular flange, with the first end face and the second end face facing each other and pressing at least one seal member therebetween. A plurality of axial retaining members are disposed around a perimeter of the mated first and second annular flanges to hold the pipe joint together.

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.
