Phloroglucinol Carboxylic Acid
Phloroglucinol carboxylic acid is a trihydroxybenzoic acid, a type of phenolic acid. It is produced by ''Pseudomonas fluorescens''. It is a catechin degradation product excreted by the bacterium ''Acinetobacter calcoaceticus'', a species of bacteria part of the human body normal flora, grown on catechin as sole source of carbon. It is also found in wine.C. García Barroso, R. Cela Torrijos and J. A.

Pseudomonas Fluorescens
''Pseudomonas fluorescens'' is a common Gram-negative, rod-shaped bacterium. It belongs to the ''Pseudomonas'' genus; 16S rRNA analysis as well as phylogenomic analysis has placed ''P. fluorescens'' in the ''P. fluorescens'' group within the genus, Text was copied from this source, which is available under Creative Commons Attribution 4.0 International License to which it lends its name. General characteristics ''Pseudomonas fluorescens'' has multiple flagella. It has an extremely versatile metabolism, and can be found in the soil and in water. It is an obligate aerobe, but certain strains are capable of using nitrate instead of oxygen as a final electron acceptor during cellular respiration. Optimal temperatures for growth of ''P. fluorescens'' are 25–30° C. It tests positive for the oxidase test. It is also a nonsaccharolytic bacterial species. Heat-stable lipases and proteases are produced by ''P. fluorescens'' and other similar pseudomonads. These enzymes cause m ...

Catechin
Catechin is a flavan-3-ol, a type of secondary metabolite providing antioxidant roles in plants. It belongs to the subgroup of polyphenols called flavonoids. The name of the catechin chemical family derives from ''catechu'', which is the tannic juice or boiled extract of ''Mimosa catechu'' (''Acacia catechu'' L.f). Chemistry Catechin possesses two benzene ring Benzene is an organic chemical compound with the molecular formula C6H6. The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atom ...s (called the A- and B-rings) and a dihydropyran heterocycle (the C-ring) with a hydroxyl group on carbon 3. The A-ring is similar to a resorcinol moiety while the B-ring is similar to a catechol moiety. There are two chirality (chemistry), chiral centers on the molecule on carbons 2 and 3. Therefore, it has four diastereoisomers. Two of the isomers are in trans configura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acinetobacter Calcoaceticus
''Acinetobacter calcoaceticus'' is a bacterial species of the genus ''Acinetobacter''. It is a nonmotile, Gram-negative coccobacillus. It grows under aerobic conditions, is catalase positive and oxidase negative. ''A. calcoaceticus'' is a part of the A. calcoaceticus-A. baumannii complex together with ''Acinetobacter baumannii'', ''Acinetobacter nosocomialis'', ''Acinetobacter pitti'' and ''Acinetobacter seifertii''. Habitat ''A. calcoaceticus'' is a soil bacterium. It has been shown to be prevalent in the tiger mosquito ''Aedes albopictus'' microflora.
