Usage

General Description

Sodium DL-Malate is a chemical compound derived from malic acid, which is found in many fruits such as apples. It is used as a food additive to add a sour taste or as a buffering agent to control the acidity of food products. Sodium DL-Malate is also used in the production of cosmetics and pharmaceuticals. It is generally recognized as safe for consumption by the FDA and is commonly used in the food industry as a flavor enhancer and preservative. Additionally, it can also be used in the treatment of metabolic disorders and as a source of energy for the body.

Enzymatic Production of L-Malate from Maleate by Alcaligenes sp.

Alcaligenes sp.T501, which has the ability to produce L-malate from maleate at a concentration of 20percent in a molar yield of 98.4percent was isolated from soil.Analysis of the reaction mixture components suggested that maleate was converted to L-malate via fumarate through the action of maleate isomerase and fumarase.These two enzymes were constitutively found in the cells regardless of the carbon source in the medium.The enzyme reaction was significantly enhanced by adding 2-mercaptoethanol, but was not affected by glutathione or L-cysteine.
