Recent advances in microbial production of L-malic acid

Applied Microbiology and Biotechnology, 2022
Over the last few decades, increasing concerns regarding fossil fuel depletion and excessive CO2 emissions have led to extensive fundamental studies and industrial trials regarding microbial chemical production. As an additive or precursor, L-malic acid has been shown to exhibit distinctive properties in the food, pharmaceutical, and daily chemical ...

X-Irradiation of L -Malic Acid in Aqueous Solutions

Radiation Research, 1956
It is the general observation that organic substances in aqueous solution undergo decomposition on exposure of the solutions to ionizing radiation. Present theories assume that solute decomposition results from chemical reactions of the solute molecules with hydrogen atoms and hydroxyl radicals formed by the radiationinduced dissociation of the water ...

Recovery of fumaric acid by membrane crystallization in the production of l-malic acid

Separation and Purification Technology, 2003
A study on redesigning traditional crystallizers by using microporous hydrophobic membranes and, in particular, the realization of a separation unit aiming to recover the unreacted fumaric acid leaving a biocatalytic membrane reactor for the production of L-malic acid is presented.

Bioconversion of Fumaric Acid to l-malic Acid by the Bacteria of the Genus Nocardia

Applied Biochemistry and Biotechnology, 2014
The bacterial strains of the genus Nocardia were used for the bioconversion of fumaric acid to L-malic acid. The ability of the bacterial strain Nocardia sp. CCM 4837/A to produce L-malic acid from fumaric acid was investigated under various conditions. The optimal temperature for the bioconversion was approximately 37 °C, and the optimal pH was around

Enzymatic determination of l-malic acid in honey

Food Chemistry, 1998
L-Malic acid determination has been carried out in honey using a direct enzymatic method. The sample solution was prepared from 2.5 g honey in 100 ml Milli-Q water. The enzymatic determination was measured spectrophotometrically at 340 nm, using glutamate-oxaloacetate transaminase and L-malate dehydrogenase. The direct method combines precision (CV was

A Bioreactor-Crystallizer for L-Malic Acid Production

Biocatalysis, 1988
A bioreactor with associated crystallizer for the accumulation of a highly concentrated slurry product has been developed and investigated. The transformation of Ca-fumarate to Ca-L-malate by the action of the fumarase of immobilized Brevibacterium flavum cells focussed on the performance of this newly-devised bioreactor-crystallizer system.The ...
