Gluconic acid, the oxidation product of glucose, is a mild neither caustic nor corrosive, non toxic and readily biodegradable organic acid of great interest for many applications. As a multifunctional carbonic acid belonging to the bulk chemicals and due to its physiological and chemical characteristics, gluconic acid itself, its salts (e.g.

The Preparation and Properties of D-Gluconic Acid and the Gluconates
2023The metallic gluconates seem to crystallize mainly in the form of warty aggregates of needles. Their optical rotation is low and generally dextro. They seem to be unstable toward heat decomposing in the vicinity of 100°C. All of them are apparently soluble in water to some extent.

Gluconic acid production byPenicillium puberulum
Folia Microbiologica, 1975Twenty-five Penicillium species isolated from Egyptian soil were examined for their ability to produce gluconic acid in surface culture. Of the eight species capable of producing gluconic acid, Penicillium puberulum gave the maximum yield (91% gluconic acid from glucose after 7 days of fermentation with 3% CaCO3).

The production of 2-keto-D-gluconic acid from glucose and also from gluconic acid by Pseudomonas species was at one time considered to be a feature which differentiated these organisms from Acetobacter species. Bernhauer and co-workers1–3 showed, however, that twelve species of Acetobacter produced from glucose a strongly reducing acid which formed a ...

Sodium gluconate and calcium gluconate methods are important techniques available for gluconic acid fermentation. The comparative analysis of these fermentations has been addressed using Aspergillus niger. The techniques are equally influenced by the spores age in slant growth, inoculum level in germination and production media, different levels of Fe,

Biotechnological production of gluconic acid: future implications
Applied Microbiology and Biotechnology, 2007Gluconic acid (GA) is a multifunctional carbonic acid regarded as a bulk chemical in the food, feed, beverage, textile, pharmaceutical, and construction industries. The favored production process is submerged fermentation by Aspergillus niger utilizing glucose as a major carbohydrate source, which accompanied product yield of 98%.
