Bradyrhizobium japonicum
Encyclopedia
Bradyrhizobium japonicum is a species of legume-root nodulating, microsymbiotic nitrogen-fixing bacterium species. B. japonicum is identified as a DNA homology group (group II).
B. japonicum is able to degrade catechin
with formation of phloroglucinol carboxylic acid
, further decarboxylated to phloroglucinol
which is dehydroxylated to resorcinol
and hydroxyquinol

B. japonicum is able to degrade catechin
Catechin
Catechin is a natural phenol antioxidant plant secondary metabolite. The term catechins is also commonly used to refer to the related family of flavonoids and the subgroup flavan-3-ols ....

Phloroglucinol carboxylic acid
Phloroglucinol carboxylic acid is a trihydroxybenzoic acid, a type of phenolic acid. 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...

Phloroglucinol
Phloroglucinol is a benzenetriol. It is an organic compound that is used in the synthesis of pharmaceuticals and explosives. This molecule exists in two forms, or tautomers, 1,3,5-trihydroxybenzene, which has phenol-like, and 1,3,5-cyclohexanetrione , which has ketone-like character. These two...

Hydroxyquinol
Hydroxyquinol is a benzenetriol.It is a catechin biodegradation product formed by Bradyrhizobium japonicum.Hydroxyquinol 1,2-dioxygenase is an enzyme that uses hydroxyquinol and O2 to produce 3-hydroxy-cis,cis-muconate....
