Clostridium acetobutylicum is an organism historically used for industrial-scale production of the organic solvents acetone, n-butanol, and ethanol (ABE) through a process known as ABE fermentation10.
What type is Clostridium acetobutylicum?
Clostridium acetobutylicum belongs to a group of Gram-positive and endospore forming anaerobes and is considered to be a model organism for solventogenic clostridia due to its acetone–butanol–ethanol (ABE) fermentation metabolism.
Is Clostridium acetobutylicum a pathogen?
C. acetobutylicum is completely benign to both plants and animals, however, many other species in the Clostridium genus are known pathogens, including: Clostridium difficile, Clostridium botulinum, Clostridium tetani, and Clostridium perfringen.
Is Clostridium acetobutylicum an obligate anaerobe?
The endospore forming, gram-positive Clostridium acetobutylicum is a classic example of fermentative obligate anaerobes. Under anaerobic conditions, it ferments sugars or starch to acetate and butyrate and then shifts them to solvents such as butanol, acetone and ethanol.
Who discovered Clostridium acetobutylicum?
Chaim Weizmann Isolates of Clostridium acetobutylicum were first identified between 1912 and 1914, and these were used to develop an industrial starch-based acetone, butanol, and ethanol (ABE) fermentation process, to produce acetone for gunpowder production, by Chaim Weizmann during World War I (13, 34, 82, 87).
How do you pronounce Acetobutylicum?
Who used bacteria to produce acetone?
It was developed by chemist Chaim Weizmann and was the primary process used to produce acetone, which was needed to make cordite, a substance essential for the British war industry during World War I.
Does Clostridium Butylicum produce lactic acid?
acetobutylicum and C. beijerinckii, were able to produce lactic acid from a complex substrate without additional of vitamins, buffer solution and micronutrients. The production of lactic acid was favored presenting a final concentration of 7.136 g L-1, in the condition of 20,000 mg l-1 of COD.
What is the product of Clostridium Butylicum?
Clostridium Butylicum is a Gram-positive, anaerobic, endospore-forming bacteria used to commercially produce butyric acid, acetone, ethanol, and butanol from starch.
What is butanol used for?
Butanol is an alcohol comprised of a four-carbon structure with the chemical formula C4H10O. It has been primarily used as a solvent found in paints and can also be utilized as a fuel. Butanol formed from plant material is often referred to as biobutanol. It is chemically similar to butanol produced from petroleum.
How does Clostridium produce acetone?
In order to produce acetone, fermentation with Clostridium should be conducted2946 between 28 and 32 °C, maintaining the pH between 5.8 and 6.1. Generally speaking, the amylase system providing the acetone–butanol fermentation contains amylolytic, dextrinolytic, and saccharifying components.
Is Clostridium Butyricum aerobic or anaerobic?
Clostridium butyricum is a strictly anaerobic, Gram-positive, spore-forming bacillus named for its capacity to produce high amounts of butyric acid.
Which acidic fermentation type is carried out by Clostridium species?
Propionic acid fermentation is carried out by several bacteria that belong to the genus Propionibacterium and to the species Clostridium propionicum. During propionic acid fermentation, both sugar and lactate can be used as the initial substrate.

What is the other name of acetone?
Acetone is a manufactured chemical that is also found naturally in the environment. It is a colorless liquid with a distinct smell and taste. It evaporates easily, is flammable, and dissolves in water. It is also called dimethyl ketone, 2-propanone, and beta-ketopropane.
How is acetone fermented?
Acetone and butanol are produced through anaerobic fermentation by species of Clostridium butyricum.
What does Clostridium ferment?
Clostridia are anaerobic bacteria that ferment a wide variety of carbon sources, including glucose, galactose, cellobiose, mannose, xylose, and arabinose [37,38].
What is the use of acetobacter?
Acetobacter aceti is economically important because it is used in the production of vinegar by converting the ethanol in wine into acetic acid. The acetic acid created by A. aceti is also used in the manufacturing of acetate rayon, plastics production, rubber production, and photographic chemicals.
Which is the good producer of citric acid?
Aspergillus niger A good producer of citric acid is Aspergillus niger (a fungus).
Is citric acid fermented?
Citric acid is exclusively produced by fermentation with filamentous fungus Aspergillus niger. The industrial production is performed using carbohydrates or agro-industrial residues as substrates by three different type processes: submerged, surface, and solid fermentations.
Does methanobacterium produce lactic acid?
D. Hint: Microbes have the ability for conversion of carbohydrates into the organic acids. … This ability of the microorganisms can be used in the commercial production of various products that can be helpful in day to day life.

Which one of the following is a wrong matching of a microbe and its industrial product, while the remaining three are correct? Solution: Clostridium acetobutylicum is a commercially valuable bacterium. … This bacteria produces lactic acid as the major metabolic end-product of carbohydrate fermentation.
What is the commercial product of Trichoderma Polysporum?

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
