Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Computed Properties of C5H4N2O3, 20737-42-2, Name is 3-Oxo-3,4-dihydropyrazine-2-carboxylic acid, molecular formula is C5H4N2O3, belongs to Pyrazines compound. In a document, author is Jaramillo, David A., introduce the new discover.
Biocatalytic Potential of Native Basidiomycetes from Colombia for Flavour/Aroma Production
Aromas and flavours can be produced from fungi by either de novo synthesis or biotransformation processes. Herein, the biocatalytic potential of seven basidiomycete species from Colombia fungal strains isolated as endophytes or basidioma was evaluated.Ganoderma webenarium,Ganoderma chocoense, andGanoderma stipitatumwere the most potent strains capable of decolourizing beta,beta-carotene as evidence of their potential as biocatalysts for de novo aroma synthesis. Since a species’ biocatalytic potential cannot solely be determined via qualitative screening using beta,beta-carotene biotransformation processes, we focused on using alpha-pinene biotransformation with mycelium as a measure of catalytic potential. Here, two strains ofTrametes elegans-namely, the endophytic (ET-06) and basidioma (EBB-046) strains-were screened. Herein,T. elegansis reported for the first time as a novel biocatalyst for the oxidation of alpha-pinene, with a product yield of 2.9 mg ofcis-Verbenol per gram of dry weight mycelia used. The EBB-046 strain generated flavour compounds via the biotransformation of a Cape gooseberry medium and de novo synthesis in submerged cultures. Three aroma-producing compounds were identified via GC-MS-namely, methyl-3-methoxy-4H-pyran-4-one, hexahydro-3-(methylpropyl)-pyrrolo[1,2-a]pyrazine-1,4-dione, and hexahydro-3-(methylphenyl)-pyrrolo[1,2-a]pyrazine-1,4-dione.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 20737-42-2. Computed Properties of C5H4N2O3.
