<i>In situ</i> reactive extraction with oleic acid for process intensification in amine transaminase catalyzed reactions

Stereospecificity of reactions catalyzed by bacterial D-amino acid transaminase.

The spectral shift from 420 to 338 nm when pure bacterial D-amino acid transaminase binds D-amino acid substrates is also exhibited in part by high concentrations of L-amino acids (L-alanine and L-glutamate) but not by simple dicarboxylic acids or monoamines. Slow processing of L-alanine to D-alanine was observed both by coupled enzymatic assays using D-amino acid oxidase and by high pressure l...

Process Intensification of Nicotinic Acid Production via Enzymatic Conversion using Reactive Extraction

Nicotinic acid is widely used in the food, pharmaceutical and biochemical industries. Compared to chemical methods, enzymatic conversion of 3-cyanopyridine is an advantageous alternative for the production of nicotinic acid and nicotinamide. The separation of the product is complicated, owing to its high dilution rate in fermentation broth and high cost. Reactive liquid-liquid extraction by a s...

Process Intensification for Separation of Carboxylic Acids from Fermentation Broths using Reactive Extraction

The potential role of a new energy efficient fermentation technology has been receiving growing attention in past 4 decades. Carboxylic acids such as propionic acid, lactic acid, citric acid, tartaric acid, itaconic acid, butyric acid and nicotinic acid etc. have been used as the most efficient fermentation chemicals. This paper presents a state-of-art review on the development of the separatio...

Intensification of Recovery of Nicotinic Acid Using Reactive Extraction: Equilibrium Study

Nicotinic acid is widely used in the food, pharmaceutical and biochemical industries. Fermentation technology for the production of nicotinic acid in particular has been known for more than a century and acid have been produced in aqueous solutions. Reactive liquid-liquid extraction for the recovery of the organic acids by a suitable extractant has been found to be a promising alternative to th...
