NOVELTY - A biological pure culture comprises new Clostridium ragsdalei similar to microorganism deposited as ATCC Nos. BAA-622 or PTA-7826.    USE - For producing ethanol from carbon dioxide source e.g. syngas (claimed) and other waste gases such as oil refinery waste gases, gases (containing some hydrogen) which are produced by yeast fermentation and some clostridial fermentations, gasified cellulosic materials, coal gasification etc. Also useful for producing liquid products e.g. butanol and acetate by fermenting carbon monoxide.    ADVANTAGE - The microorganism is capable of producing high yields of ethanol and acetic acid by fermenting carbon monooxide or its source e.g. syngas. The microbes can thus convert substances that would otherwise be waste products into valuable products e.g. biofuels. Syngas, and thus carbon monoxide, can also be produced from readily available low-cost agricultural raw materials by pyrolysis, providing a means to address both economic and environmental concerns of energy production. The bacteria participates in the indirect conversion of biomass to biofuel via a gasification/fermentation pathway. Cultures of Clostridium ragsdalei are extremely stable and can be stored on the at room temperature or in a 38degrees C incubator for over one year while retaining activity. It provides microbes that are robust, relatively easy to culture and maintain, and that provide good yields of products of interest, such as biofuels.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1) a composition comprising a source of carbon monoxide, and Clostridium ragsdalei; 2) producing ethanol, involving combining a source of carbon monoxide and Clostridium ragsdalei under conditions which allow the Clostridium ragsdalei to convert carbon monoxide to ethanol; and 3)a system for producing ethanol comprising a vessel in which a source of carbon monoxide is combined with Clostridium ragsdalei; and a controller which controls conditions in the vessel which permit the Clostridium ragsdalei to convert the carbon monoxide to ethanol.
