Clostridium saccharobutylicum is an indole and notably acetone, butanol and ethanol-producing bacterium, with type strain DSM 13864 T (= ATCC BAA-117 T). [ 1 ] [ 2 ] Its genome has been sequenced. [ 3 ]
Acetone, butanol, and ethanol are the most common products of solventogenesis. Some species such as Clostridium beijerinckii, Clostridium puniceum and Clostridium roseum are able to further reduce acetone to isopropanol. Several species are able to produce additional solvents under various culture conditions.
The ABE fermentation produces solvents in a ratio of 3 parts acetone, 6 parts butanol to 1 part ethanol. It usually uses a strain of bacteria from the Class Clostridia (Family Clostridiaceae). Clostridium acetobutylicum is the most well-studied and widely used.
Some species within the genus Clostridium are capable of producing biochemicals and biofuels. This fermentation process is able to produce acetone, butanol, and ethanol and is one of the first commercial fermentation processes used for bulk chemical production. This species has also been used in therapy, research, and even cosmetics (such as ...
Most species of the genus Clostridium are saprophytic organisms that ferment plant polysaccharides [2] and are found in many places in the environment, most notably the soil. However, the genus does contain some human pathogens (outlined below). The toxins produced by certain members of the genus Clostridium are among
Clostridium acetobutylicum, ATCC 824, is a commercially valuable bacterium sometimes called the "Weizmann Organism", after Jewish Russian-born biochemist Chaim Weizmann. A senior lecturer at the University of Manchester , England , he used them in 1916 as a bio-chemical tool to produce at the same time, jointly, acetone , ethanol , and n ...
Clostridium beijerinckii is a gram positive, rod shaped, motile bacterium of the genus Clostridium. It has been isolated from feces and soil. It has been isolated from feces and soil. Produces oval to subterminal spores.
Primary nutritional groups are groups of organisms, divided in relation to the nutrition mode according to the sources of energy and carbon, needed for living, growth and reproduction. The sources of energy can be light or chemical compounds; the sources of carbon can be of organic or inorganic origin.
