“…Most likely, this was due to the fact that the artichoke hydrolysate included a mixture of sugars (glucose and fructose). Zeng et al noted that BC production with maple syrup was almost as high as when using pure fructose and much higher than when using glucose [46], and this fact is consistent with the viewpoint that the composition of sugars does not affect BC production if fructose exists in the medium, possibly because fructose activates a phosphoenolpyruvate-dependent phosphotransferase system in A. xylinum [47]. In addition, it is worth noting that all the glucose was fully utilized by cells, and the residual concentration of fructose was 22.7 g/L.…”

Abstract:A new biocatalyst in the form of Komagataeibacter xylinum B-12429 cells immobilized in poly(vinyl alcohol) cryogel for production of bacterial cellulose was demonstrated. Normally, the increased bacteria concentration causes an enlarged bacterial cellulose synthesis while cells push the polysaccharide out to pack themselves into this polymer and go into a stasis. Immobilization of cells into the poly(vinyl alcohol) cryogel allowed "deceiving" them: bacteria producing cellulose pushed it out, which further passed through the pores of cryogel matrix and was accumulated in the medium while not covering the cells; hence, the latter were deprived of a possible transition to inactivity and worked on the synthesis of bacterial cellulose even more actively. The repeated use of immobilized cells retaining 100% of their metabolic activity for at least 10 working cycles (60 days) was performed. The immobilized cells produce bacterial cellulose with crystallinity and porosity similar to polysaccharide of free cells, but having improved stiffness and tensile strength. Various media containing sugars and glycerol, based on hydrolysates of renewable biomass sources (aspen, Jerusalem artichoke, rice straw, microalgae) were successfully applied for bacterial cellulose production by immobilized cells, and the level of polysaccharide accumulation was 1.3-1.8-times greater than suspended cells could produce.

“…Traditional sources of carbon for microbial fermentation are sugars such as glucose, fructose, and sucrose (Bae and Shoda 2005). More recently, unconventional feedstocks from renewable resources and waste streams have been investigated (Zeng et al 2011). These include fruit juices (Kurosumi et al 2009), sugar cane molasses (Keshk and Sameshima 2006), sweet potato pulp (Shigematsu et al 2005), rotten apples (Gupta et al 2010), and maple syrup (Zeng et al 2011).…”

The optimum conditions for producing vinegar from Jujube (ziziphus jujuba) juice using Acetobacter aceti were exploited by employing the response surface methodology (RSM). In addition to the initial concentration of ethanol, which is known to be a significant factor affecting acetic acid fermentation, the effects of initial concentration of Jujube juice, A. aceti concentration, pH, and temperature on acetic acid fermentation were also investigated. Out of these factors, the effects of the initial concentration of jujube juice and inoculation amount of A. aceti were determined to be negligible based on statistical analysis. By employing the face-centered experimental design in RSM, the optimum conditions for acetic acid fermentation were exploited for achieving maximum acidity and acetic acid production. The coefficients (R 2 ) of the derived equations from the response surface regression were 0.71 and 0.78 for acidity and acetic acid production, respectively. The maximum production of acetic acid was expected to be 52.76 mg/mL from 25% jujube extract at 21.75 o C with 7.69% alcohol content.
