Abstract: A methanogenic reactor for the production of methane, cellular biomass and other useful products for use in the manufacturing of specialty chemicals. The methanogenic reactor includes a bottom wall, perimeter wall, and top wall defining an interior space environmentally separable from an exterior space outside of the reactor vessel for holding a methanogenic culture and growth media. The reactor also includes at least one sparger positioned substantially within the interior space for facilitating the direction of an input gas stream into the reactor to be brought into contact with the methanogenic culture. The reactor also includes an output material stream port for releasing an output material stream created at least in part by the methanogenic culture.

Abstract: A system for the production of methane and other useful products and method of use for generating green natural gas as a fuel or component for use in the manufacturing of specialty chemicals. The system for the production of methane and other useful products and method of use includes a culture of methanogenic archea for converting an input material into an output material, a reactor vessel for housing at least a portion of the culture of methanogenic archea, an input material stream directed into the reactor vessel to facilitate contact between the input material stream and the methanogenic archea, and an output material stream created at least in part by the culture of methanogenic archea.

Abstract: A closure apparatus which includes a scroll-like closure panel of flexible material is used to resealably close the open end of a bag-like container. The closure panel has opposite inner and outer longitudinal edges, with its outer edge spirally wound about its inner edge. The closure panel is biased to define a coil in lateral section when the panel is in equilibrium. For closing the open end of the bag-like container, the end edges of an open end of the bag-like container are spirally captivated within the coil defined by the closure panel.
