Gluconic production

Hie two main differences between caldum gluconate and sodium gluconate production are that, in the latter, pH control is performed by addition of sodium hydroxide and the initial glucose concentration is different...

The cyclization of pentaacetyl-o-gluconic thioamide with chloroacetone and of pentaacetyl-D-galactonic acid thioamide with phenacyl bromide give the corresponding 4-substituted 2-(D-galactopentaacetoxypentyl)-thiazoles (27) (660) but in low yield (23 to 27%) (Scheme 13). The products may be deacetylated in the usual way. These compounds are interesting from a pharmacological point of view. 

The main product appears as a result of primary energy metabolism. Examples production of biomass, ethanol and gluconic acid. 

The ability of bacteria - particularly Pseudomonas spp. and Glucottobader spp. - to produce gluconolactone and gluconic acid has been exploited and the process is used commerdally, mainly in the production of the lactone. 

The control of glucose oxidase production is still not fully eluddated, nor is the role of gluconic add in cells. However, elevated levels of glucose oxidase are found in conditions of high glucose concentrations and above normal oxygen tension.
