Production of gluconic acid using Micrococcus sp.: optimisation of carbon and nitrogen sources. Hindustan Antibiotics Bulletin. 1996 Feb-Nov; 38(1-4): 57-65http://imsear.searo.who.int/handle/123456789/2313A process for production of gluconic acid from glucose by a Micrococcus sp. is described. More than 400 bacterial cultures isolated from local soil were tested for gluconic acid production. Three isolates, were selected on basis of their ability to produce gluconic acid and high titrable acidity. These were identified as Micrococcus sp. and were named M 27, M 54 and M 81. Nutritional and other parameters for maximum production of gluconic acid by the selected isolates were optimised. It was found that Micrococcus sp. isolate M 27 gave highest yield of 8.19 g gluconic acid from 9 g glucose utilised giving 91% conversion effeciency.engCarbon --chemistryCulture MediaGluconates --isolation & purificationGlucose --metabolismLithiumMethodsMicrococcus --geneticsNitrogen --chemistryZincJournal Article
