Statistical approach to optimization of fermentative production of gellan gum from Sphingomonas paucimobilis ATCC 31461

Production and Rheological Properties of Welan Gum Produced by <b><i>Sphingomonas</i></b> sp. ATCC 31555 with Different Nitrogen Sources

“…In general, both the type and concentration of the nitrogen source in the medium affect the flow of carbon to the bacteria and the production of EPS [Ashtaputre and Shah, 1995]. A previous study found that different nitrogen sources affect the production of gellan gum from Sphingomonas paucimobilis ATCC 31461 [Bajaj et al, 2006]. These studies indicate the key role of the nitrogen source in EPS production.…”

Optimization of exopolysaccharide production from Pseudomonas stutzeri AS22 and examination of its metal-binding abilities

“…While Bajaj et al . () reported soluble starch to be suitable for maximum production of both biomass and gellan gum, Nampoothiri et al . () found that maximum gellan and biomass production were obtained with soluble starch and glucose as sole carbon sources, respectively.…”

Compactin production in solid-state fermentation using orthogonal array method by P. brevicompactum

“…This confirmed the robustness of solution for optimal levels of parameters identified from Taguchi's orthogonal array. Taguchi's orthogonal arrays have been used successfully for the optimization studies for production of gellan gum [30]. Similarly the nutritional requirements and environmental conditions for submerged culture of Streptomyces clavuligerus for clavulanic acid production were optimized using Taguchi L 16 design matrix [31].…”

“…The Taguchi's orthogonal arrays offer the identification of factor main effects in a relatively few number of runs. Although interaction effects among factors are also involved in fermentation processes, however Taguchi's designs are nevertheless useful for process optimization and had been used recently for optimization of fermentative process [30,31]. The production of compactin by P. brevicompactum WA 2315 occurs at a late stage of stationary phase.…”
