A continuous process for production of d-ribulose-1,5-bisphosphate from d-glucose

“…Nevertheless, the non-enzymatic proteins also represent a suitable repertoire of such potential scaffolds, which could be used for development as sugar-binding proteins to be used in reactors for simultaneous separation of sugars that would be used in subsequent conversion steps. We have developed a RuBP production scheme from 3PGA [16,17] and also a de novo RuBP production scheme from D-glucose [21] for continuous CO 2 fixation and for start-up of the fixation respectively employing series of reactors. Both systems for production of RuBP will benefit from specific sugar binders but besides their use in environmental biotechnology, they will find application in diagnostics, separation technologies and also as research reagents.…”

“…However, inasmuch as the recycling of acceptor RuBP is central to continuous CO 2 fixation, we have invented a novel scheme (Figure 1), which proceeds with no loss of CO 2 (unlike cellular biochemical systems) in 11 steps in a series of bioreactors [20]. This scheme is very different from generation of RuBP from D-glucose for start-up process [21] and employing 11 steps in different reactors requiring large volume and weight. The linear combination of reactors with large volume and weight are unsuitable for use with mobile CO 2 emitters leaving only the stationary source of emission to be controlled using this technology [17].…”

“…For starting up the process, however, a different scheme was used to generate RuBP from D-glucose rather than from 3-PGA [14]. The linear combination of reactors in the 11 step RuBP regeneration process requires large volume and weight and are unsuitable for use in mobile CO 2 emitters leaving only the stationary source of emission to be controlled using this technology [8,9].…”
