Organic acids bioproduction from corn fiber using Actinobacillus succinogenes
Succinic acid (SA) and lactic acid (LA) are organic acids which are used to synthesize high value industry chemicals, which have applications in the food, agricultural, chemical, and pharmaceutical industries. Currently, these acids are produced primarily from fossil-fuel feedstocks, which are …

Metal Dissolution From Silver Plated Flatware by Organic Acids
… plated flatware pieces when they are exposed to organic acids of the type and concentration commonly found in foods. Examples of heirloom flatware, including those composed of the nickel silver class of alloys, were exposed to 0.1M and 1.0M acetic, citric, and lactic acid at room temperature and …

Controlling dark fermentation of agro-industrial waste for valued organic acids production
… on the social and economic balance. Organic waste contains valuable compounds, worth recovering. Traditional waste management methods are typically based on aerobic treatment and anaerobic digestion (AD) of the organic substrate, or a combination of them. From these traditional …

Poultry Performance and Food Safety Impacts of Selected Organic Acids and Probiotics
… was conducted to evaluate the use of selected organic acids in controlling foodborne pathogens and improving poultry performance. Then, the characterization and application of lactic acid bacteria and <em>Bacillus</em> spp. based probiotics in poultry, and their combination, along with early …

Modeling the Effects of Acid Deposition and Natural Organic Acids on Surface Waters
<p>Atmospheric deposition of sulfuric and nitric acids has impacted surface waters in the eastern U.S. Controls on anthropogenic S and NOx emissions have resulted in a substantial decrease in acid deposition. Long-term measurements of surface water chemistry indicate contrasting responses of …

The Influence of Residence Time and Organic Acids on the Desorption of Goethite
… to examine the influence of residence time and organic acids on the desorption of Pb2+and Cd2+ from goethite. Adsorption experiments were conducted at pH 6.0. Lead adsorption was nearly completed after 4 hours, with very little additional sorption during a 20-week period. In contrast cadmium …

Metabolic Pathways of Amino Acids, Monosaccharides and Organic Acids in Soils assessed by Position-Specific Labeling
Transformation of low molecular weight organic substances (LMWOS) is one of the most important steps in biogeochemical cycles since all high molecular substances pass this stage during their decomposition. Microbial utilization is the most relevant sink for LMWOS in soils and thus knowledge about …

Liberation of low molecular weight organic acids from sedimentary organic matter and their role on microbial activity
Low molecular weight organic acids (LMWOAs) are important nutrients for microbes. However, most LMWOAs do not exist freely in the environment but are bound to macromolecular organic matter, e.g. kerogen, lignite and coal. During burial and geological maturation of sedimentary macromolecular organic …
