Efficient malic acid production from glycerol with Ustilago trichophora TZ1.
BACKGROUND The large surplus of crude glycerol, as main low-value waste stream in biodiesel production, has led to the investigation of new possibilities for the production of value-added chemicals from this feedstock. New and efficient (bio-) catalysts are needed that are able to convert glycerol to versatile chemical building blocks. This would contribute to further develop away from a mainly...
متن کاملIdentification of malic acid from yeast.
Evidence indicated an accumulation of l-malic acid in the synthetic growth medium of both lysine auxotrophs and wild-type yeast. Malic acid was isolated from growth experiments and was identified by paper and column chromatography, by comparison of infrared spectra with authentic l-malic acid, as well as enzymatically, as a substrate of malic dehydrogenase. Malic acid was accumulated when gluco...
متن کاملMalic Acid & Metabolic Acidosis
Label-MMAcid-Rev030410 BACKGROUND Ruminants are animals that have multiple stomachs to allow consumption and digestion of fibrous feedstuffs. Key to this digestive process is the bacterial breakdown of the fiber in the first stomach or rumen. The bacterial balance in the rumen can shift, allowing the ruminant to adapt to different diets. Ruminal bacteria convert fiber into lactate and volatile ...
متن کاملMicrobial Production of Malic Acid from Biofuel-Related Coproducts and Biomass
The dicarboxylic acid malic acid synthesized as part of the tricarboxylic acid cycle can be produced in excess by certain microorganisms. Although malic acid is produced industrially to a lesser extent than citric acid, malic acid has industrial applications in foods and pharmaceuticals as an acidulant among other uses. Only recently has the production of this organic acid from coproducts of in...
متن کاملEnhanced malic acid production from glycerol with high-cell density Ustilago trichophora TZ1 cultivations
BACKGROUND In order to establish a cost-efficient biodiesel biorefinery, valorization of its main by-product, crude glycerol, is imperative. Recently, Ustilago trichophora TZ1 was found to efficiently produce malic acid from glycerol. By adaptive laboratory evolution and medium optimization, titer and rate could be improved significantly. RESULTS Here we report on the investigation of this st...
