How succinic acid is produced?
Succinic acid can be produced via catalytic hydrogenation of maleic acid or maleic anhydride, a process that is both expensive and harmful to the environment. It could also be produced via fermentation.
Which Anaerobe produces succinic acid in abundance?
Obligate anaerobes such as Anaerobiospirillum succiniciproducens and Actinobacillus succinogenes produce high concentrations (up to 110 g/L) of succinic acid from various carbon sources, with an apparent yield of 1.2 mol/mol or 0.78 g/g glucose consumed [88].
Where is succinic acid produced?
Succinic acid can be produced through the fermentation of microorganisms, such as Actinobacillus succinogenes on fermentable carbon sources [1, 2]. Because of its low cost and abundance, lignocellulosic feedstock is attractive as a raw material for producing succinic acid.
Which bacteria is used in succinic acid fermentation?
Microbial production of Succinic acid can be performed with wild bacteria like Actinobacillus succinogenes, Mannheimia succiniciproducens and Anaerobiospirillum succiniciproducens or genetically modified Escherichia coli, Corynebacterium glutamicum and Saccharomyces cerevisiae.
Is succinate and succinic acid the same?
Succinate(2-) is a dicarboxylic acid dianion resulting from the removal of a proton from both of the carboxy groups of succinic acid. It has a role as a human metabolite and a Saccharomyces cerevisiae metabolite. It is a C4-dicarboxylate, a dicarboxylic acid dianion and a succinate.
What causes high succinic acid?
The most common cause of elevated succinic acid is exposure to toxic chemicals which impairs mitochondria function.
Can E coli grow on succinate?
Escherichia coli atp mutants, which lack a functional H+-ATPase complex, are capable of growth on glucose but not on succinate or other C4-dicarboxylates (Suc− phenotype).
What is the role of succinic acid?
Applications. TCC’s succinic acid is used as a flavoring agent for food and beverages. Producing five heterocyclic compounds, it is used as an intermediate for dyes, perfumes, lacquers, photographic chemicals, alkyd resins, plasticizers, metal treatment chemicals, and coatings.
What is succinate fermentation?
In the biological systems, succinate is an essential intermediate for cellular metabolism. In addition, it can also be one of the end-products of anaerobic fermentation. Therefore, it is possible to produce succinate using biological processes to substitute the petrochemicals processes.
What is succinic acid used for?
It is a common organic acid, which can be used in many food, chemical, and pharmaceutical industries as a precursor to generate many chemicals such as solvents, perfumes, lacquers, plasticizer, dyes, and photographic chemicals. Succinic acid is also used as an antibiotic and curative agent.
How can you synthesize succinic acid from ethyl acetoacetate?
The reaction of sodium ethyl acetoacetate with ethyl chloroacetate (CICH₂COOC₂H₂) followed by acid hydrolysis gives succinic acid. If we start with sodium alkylacetoacetic esters, alkylsuccinic acids are formed. with an alkylene diiodide followed by acid hydrolysis gives a normal dicarboxylic acid.
What is another name for succinic acid?
Butanedioic Acid
succinic acid, also called Butanedioic Acid, a dicarboxylic acid of molecular formula C4H6O4 that is widely distributed in almost all plant and animal tissues and that plays a significant role in intermediary metabolism.
What is succinate in biology?
succinate A salt of succinic (butanedioic) acid, HOOC(CH 2) 2COOH, a four-carbon fatty acid. Succinate occurs in living organisms as an intermediate in metabolism, especially in the Krebs cycle. A Dictionary of Biology.
Is succinate a carbon source?
Microalgal biomass was shown to serve as an efficient carbon source for the microbial production of succinate, which is considered as a platform chemical, when suitably engineered strains were used which are capable of starch degradation by the secretion of amylases.
How do you make succinic acid solution?

Can succinate be fermented?
Since the succinate metabolic pathway has been resolved in different biological systems, it is possible to produce this valuable chemical through microbial fermentation.
Is succinic acid and succinate the same?
In living organisms, succinic acid takes the form of an anion, succinate, which has multiple biological roles as a metabolic intermediate being converted into fumarate by the enzyme succinate dehydrogenase in complex 2 of the electron transport chain which is involved in making ATP, and as a signaling molecule …
How does glucose concentration affect the production of succinic acid?
Electrons from H 2 may be incorporated into the fermentation products resulting in the increase of succinic acid yield. 16, 17 Initial glucose concentration can affect cell viability and distribution of fermentation products as well as the level of CO 2.
Is it possible to produce succinic acid from CO2 and H2?
It was concluded that the external supply of CO2 and H2 at the optimum ratio makes it possible to produce succinic acid with a high yield and productivity. 1. Introduction
Does the initial glucose concentration affect the distribution of fermentation products?
The distribution of the fermentation products was not affected by varying the initial glucose concentration in a reasonable range, but the succinic acid yield and productivity were higher at 40 g l−1 glucose.
