“…(Temsah and Olama, 1999). The gluconic acid production by the proposed fungus was also reported in other studies (El-Kataney, 1978; Vassilve et al, 1993; Petruccioli et al, 1994; Singh et al, 1999). Our results revealed that a wide range of variations form low gluconic acid production as well as total acidity in its culture filtrate under the experimental conditions.…”

“…The production of gluconic acid is mainly done in batch cultivation using several species belonging to the following fungal genera, Aspergillus , Penicillium , Fusarium , Mucor , and Gliocladium (Lockwood, 1975; Rosenberg et al, 1992; Petruccioli et al, 1994; Singh et al, 2001). Among the different fungal genera, it has been reported that the accumulation of large amounts of the gluconic acid and its salts are restricted to certain species of Aspergillus , especially A. niger which considered as the most industrially important gluconic acid producer in fermentation industry (Roukas, 2000; Sankpal et al, 2001; Sankpal and Kullkarni, 2002; El-Enshasy, 2003).…”

Forty-one fungal species belonging to 15 fungal genera isolated from Egyptian soil and sugar cane waste samples were tested for their capacity of producing acidity and gluconic acid. For the tests, the fungi were grown on glucose substrate and culture filtrates were examined using paper chromatography analysis. Most of the tested fungi have a relative wide potentiality for total acid production in their filtrates. Nearly 51% of them showed their ability of producing gluconic acid. Aspergillus niger was distinguishable from other species by its capacity to produce substantial amounts of gluconic acid when it was cultivated on a selective medium. The optimized cultural conditions for gluconic acid yields were using submerged culture at 30℃ at initial pH 6.0 for 7 days of incubation. Among the various concentrations of substrate used, glucose (14%, w/v) was found to be the most suitable carbon source for maximal gluconic acid during fermentation. Maximum values of fungal biomass (10.02 g/l) and gluconic acid (58.46 g/l) were obtained when the fungus was grown with 1% peptone as sole nitrogen source. Influence of the concentration of some inorganic salts as well as the rate of aeration on the gluconic acid and biomass production is also described.

a b s t r a c tThe objective of this study was to isolate the potential fungal isolates have the ability for gluconic acid production by using some agro industrial byproducts as sugarcane molasses, banana-must and grape-must. The effect of gamma-irradiation on the most potent isolates and the fermentation conditions as pH, incubation temperature and incubation period was also investigated. Results showed that the most potential fungal isolates were Aspergillus niger, Penicillium puberulum and Penicillium frequentans whereas their gluconic acid production was 62.17, 56.25 and 39.69 g/L, respectively on Czapek's Dox media at 28 ± 1 C, pH 6 for 7 days fermentation period. Irradiation of the three most potential isolates at 0.1, 0.2, 0.3, 0.4 and 0.5 kGy doses of gamma ray showed that 0.1 kGy dose caused an increase in gluconic acid production whereas it was 69.35, 60.17 and 40.31 g/L by the three potential isolates respectively. Data showed that utilization of sugarcane molasses, banana-must and grape-must as a sole carbon source in gluconic acid production by the three potential (0.1 kGy) irradiated isolates at pH 6, 30 C for a 7 days incubation period caused increasing in gluconic acid production whereas the productivity of the three (0.1 kGy) irradiated isolates (A. niger, P. puberulum and P. frequentans) was 69.87, 63.14 and 51.28 g/L by utilizing sugarcane molasses, 61.28, 56.37, 47.15 g/L by utilizing banana-must and 54.25, 52.75 and 44.75 g/L by utilizing grape-must.

“…There are many reports on the fermentative production of gluconic acid and its salts by various bacterial and mould species. The commonly studied bacterial species belong to Pseudomonas, Acetobacter, Gluconobacter, Zymomonas (Bekers et al 2000;Chen & Liu 2000;Moonmangmee et al 2000), while in moulds, Penicillium, Aspergillus, Aureobasidium (Petruccioli 1994;Anastassiadis et al 2003;Singh et al 2003) have been considered suitable strains for gluconic acid production. Refined glucose, glucose syrup and sucrose have been the main substrates for gluconic acid production (Ray & Banik 1999;Silveira et al 1999;Bekers et al 2000).…”
