일반 설명

Levulinic acid (LA), is a biogenic product of hexose acid hydrolysis, produced from renewable or bio-based resources. LA is reported to react with a variety of compounds to result in products, which are widely used in pharmaceuticals, personal care products, electronics, plasticizers, antifouling compounds, fuels, solvents, polymers, anti-freeze agents, batteries, coatings, biologically active materials, corrosion inhibitors, adsorbents, etc. LA is also employed as a chemical intermediate in the production of biodegradable polymers, fuel extenders, herbicides, flavors, antibiotics and useful 5-carbon compounds.
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here

애플리케이션

Levulinic acid may be used as an analytical reference standard
for the quantification of the analyte in the following:
  • Soy sauce using liquid chromatography coupled to mass spectrometry (LC–MS).
  • Liquid food samples using gas chromatography with flame ionization detection (GC-FID).

Eastern redcedar is an invasive softwood species in Oklahoma and across grasslands in the Central Plains of the United States and potential feedstock for butanol production. Butanol has higher energy content than ethanol and can be upgraded to jet and

Yeast has long been considered the microorganism of choice for second-generation bioethanol production due to its fermentative capacity and ethanol tolerance. However, tolerance toward inhibitors derived from lignocellulosic materials is still an issue. Flocculating yeast strains often perform relatively well

Production of polyhydroxyalkanoates (PHAs) from Jatropha biodiesel residues, namely crude glycerol and oil cake hydrolysate, has been reported previously. Halomonas hydrothermalis (MTCC accession no. 5445; NCBI Genbank accession no. GU938192), a wild marine strain, was used in the bio-synthesis. The

The robust supramolecular structure of biomass often requires severe pretreatments conditions to produce soluble sugars. Nonetheless, these processes generate some inhibitory compounds (i.e. furans compounds and aliphatic acids) deriving mainly from sugars degradation. To avoid the inhibition of the biological

Carbonyl compounds generated in biomass pretreatment hinder the biochemical conversion of biomass hydrolysates to biofuels. A novel approach of detoxifying hydrolysates with amino acids for ethanol production was developed. Among the 20 amino acids assessed for their detoxification efficiency and
