Grape musts sometimes reveal excess acidity. An excessive amount of organic acids negatively affect wine yeasts and yeast fermentation, and the obtained wines are characterized by an inappropriate balance between sweetness, acidity or sourness, and flavor/aroma components. An appropriate acidity, pleasant to the palate is more difficult to achieve in wines that have high acidity due to an exces...

The roots of barley plants (Hordeum vulgare L. cv Steptoe) were monitored before and after excision for net uptake of carbon dioxide, oxygen, ammonium, potassium, nitrate, and chloride and for their content of sucrose, glucose, fructose, and malic acid. All fluxes began to attenuate within 2 hours after excision. Net potassium uptake returned to control levels 6 hours after excision, but carbon...

The purpose of this study is to investigate the effect ultrasound and/or organic acids against Escherichia coli and Listeria monocytogenes biofilms on microplates. In inactivation trials, pathogen formed microplates were exposed 2% acid (acetic, citric, malic lactic acid) for 10, 30 60 minutes. Biofilm detachment treatment with US was tested by microplate method based measuring optical density....

Malic acid production, degradation, and storage during fruit development have been modelled. The model assumes that malic acid content is determined essentially by the conditions of its storage in the mesocarp cells, and provides a simplified representation of the mechanisms involved in the accumulation of malate in the vacuole and their regulation by thermodynamic constraints. Solving the corr...

Objectives: Use of certain drugs is the most common aetiology of xerostomia. Systemic sialogogues provide a longer effect than topic ones, but also induce relevant side effects. Topical sialogogues, as malic acid, allow a safe use as they induce no systemic side-effects or pharmacological interactions, being especially interesting in cases of mild hyposalivation and oral dryness, mainly the chr...

Malic enzyme 2 (ME2) catalyzes the formation of pyruvate from malic acid and is abnormally expressed in some tumors. However, exact effects ME2 on proneural–mesenchymal transition (PMT) lipogenesis glioblastoma multiforme (GBM) remain unexplored. Here, we found that expression was significantly higher GBM than normal brain tissues negatively correlated with overall survival patients GBM. Furthe...
