BACKGROUND Integrating waste management with fuels and chemical production is considered to address the food waste problem and oil crisis. Approximately, 600 million tonnes crude glycerol is produced from the biodiesel industry annually, which is a top renewable feedstock for succinic acid production. To meet the increasing demand for succinic acid production, the development of more efficient ...

In vivo and in vitro sublethal exposure of abrin, glycyrrhizin (active component of Abrus precatorius seed and root), sanguinarine, protopine (Argemone mexicana seed) and oleandrin (Nerium indicum leaf) inhibited the acetylcholinesterase, lactic dehydrogenase, acid and alkaline phosphatase activity in the nervous tissue of Lymnaea acuminata. The succinic dehydrogenase activity in the nervous ti...

Cell recycled culture of succinic acid-producing Anaerobiospirillum succiniciproducens was anaerobically carried out using an internal membrane filter module in order to examine the physiological response of A. succiniciproducens to a high-cell-density environment. The optimal growth of A. succiniciproducens and its enhanced succinic acid productivity were observed under CO2-rich conditions, es...

Succinic acid is an important C4-building chemical platform for many applications. A novel succinic acid-producing bacterial strain was isolated from goat rumen. Phylogenetic analysis based on the 16S rRNA sequence and physiological analysis indicated that the strain belongs to the genus Enterobacter. This is the first report of a wild bacterial strain from the genus Enterobacter that is capabl...

During fermentation with baker's yeast, free suecinic acid appears rapidly in the suspending medium (Conway & Brady, 1947). With 1 part of washed centrifuged yeast to 0-6 part of 5% (w/v) glucose, forming a mixture with approximately 0-8 part of cells to 0-8 part of external fluid, about 40 m-equiv. of succinic acid per kg. cells diffuse out within 30 min., the pH of the suspending fluid fallin...

The crystal structure of the title salt adduct, 2C6H14N(+)·C4H4O4 (2-)·C4H6O4, consists of two cyclo-hexyl-ammonium cations, one succcinate dianion and one neutral succinic acid mol-ecule. Succinate dianions and succinic acid mol-ecules are self-assembled head-to-tail through O-H⋯O hydrogen bonds and adopt a syn-syn configuration, leading to a strand-like arrangement along [101]. The cyclo-hexy...

A gas-liquid chromatography technique which allows simultaneous detection of hippuric acid (N-benzoylglycine) hydrolysis and conversion of fumaric acid to succinic acid by microorganisms uses a new medium, hippurate-formate-fumarate broth, and a gas chromatograph equipped with a thermal conductivity detector. This technique gave more reproducible results than other tests used in the study for d...

Bio-succinic acid production using microorganisms has been interesting as an environmentally friendly process. Palm oil mill effluent (POME) was considered a cheap substrate to lower the cost of production. It revealed that 2-fold diluted POME produced more succinic than undiluted and 5-fold POME. In addition, effects various neutralizing agents on utilized manage pH CO2 supply indicated utiliz...
