Rayo-Inositol

Cyclitol dehydrogenases have also been detected in some strains of Aero-bacter aerogenes46 and in Mycobacterium tuberculosis BCG.46 The Aerobacter enzyme has been fairly extensively studied,45 47 and it is considered to function in the fermentation of inositol by this organism.38 Pseudomonas beijerinckii is distinguished by its ability to oxidize m /o-inositol and levo-inositol to the tetrahydroxyquinone stage,48 and Propionibacterium pento-saceum effects a dismutation of rayo-inositol in which hexahydroxybenzene appears to be the oxidized product.49... 

In addition to the limited oxidations described earlier (see p. 144), the fermentation of mt/o-inositol to two-carbon and three-carbon compounds, and its complete oxidation to carbon dioxide plus water, can be performed by a number of micro-organisms. Detailed studies have been carried out with only one organism, Aerobacter aerogenes. In the presence of arsenite, this bacterium ferments rayo-inositol according to the following equation.137...
