What is Anaerobiospirillum succiniciproducens?
Anaerobiospirillum succiniciproducens is a rare cause of bacteraemia in humans, and when encountered usually occurs in immunocompromised patients. The organism is an anaerobic, spiral shaped, Gram negative bacillus with bipolar tufts of flagella.
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].
Can E coli grow on succinate?
The E. coli atp deletion strain LM2800 is unable to grow on minimal medium supplemented with succinate as the sole carbon and energy source.
What acid does E coli produce?
Escherichia coli also produces succinic acid but as a minor fermentation product. E. coli prefers to produce much more acetic acid, formic acid, lactic acid, and ethanol rather than succinic acid during anaerobic fermentation.
Is succinate a carbon source?
To study the importance of the PEP requirement in succinate production, a carbon source that does not use the PTS system for transport was used and compared with glucose.
What acid does E. coli produce?
Where does E. coli come from?
You get an E. coli infection by coming into contact with the feces, or stool, of humans or animals. This can happen when you drink water or eat food that has been contaminated by feces.
How does E. coli grow?
It can grow with or without oxygen. In the gut, E. coli grows anaerobically (in the absence of oxygen). However, unlike some anaerobic bacteriaE. coli also grows well in aerobic environments, such as a culture flask in a laboratory.
How succinate is transported within the cell of E coli?
The uptake of succinate is competitively inhibited by fumarate and malate. The accumulation of succinate is prevented by various energy poisons and sulfhydryl reagents. Inhibitors of mitochondrial dicarboxylate transport are with- out any effect on the succinate uptake system of E. coli.
