“…The mixtures of WS-LMWC oligomers could be used as food additives for their assumed prebiotic properties and positive effects on health, as recently found using cello-oligosaccharides produced by many conventional pathways. 29,30 In addition, the WI-LMWC fraction could be used as a direct compression excipient in fast-release drugs, as LMW cellulose II powders have already shown improved properties in such applications compared to those formulated using conventional MCC. 31,32 Nevertheless, using supercritical water to hydrolyse cellulose remains a recent approach and its potential beyond that of scientific curiosity remains unclear even today.…”

Supercritical water hydrolysis: a green pathway for producing low-molecular-weight cellulose

et al. 2016

This work discusses the suitability of supercritical water treatment (SCWT) for depolymerising microcrystalline cellulose in a controlled way. The SCWT partially hydrolysed cellulose down to a mixture of three valuable products: water-insoluble low-molecular-weight cellulose (WI-LMWC) precipitate, water-soluble low-molecular-weight cellulose (WS-LMWC) oligomers, and glucose. The conditions under which the energy demand for obtaining these products is minimised were identified by adjusting the reaction time inside the continuous reactor and the temperature around the critical point. The optimum conditions were 370°C and 0.4 seconds for producing WI-LMWC and 360°C and 0.5 seconds for producing WS-LMWC, with maximum yields of 19 wt% and 50 wt%, respectively. This work also shows that the water-insoluble product precipitates into crystalline cellulose II arrangements. This precipitation phenomenon enabled isolation of cellulose chains of different lengths according to their respective solubilities in ambient water. The results show that SCWT is a relevant process for producing narrowly distributed fractions of low-molecular-weight cellulose using water and heat only. † Electronic supplementary information (ESI) available.

“…Similarly, Celestin et al ( 2015 ) reported that FOS supplementation in goat milk yogurts resulted in a higher cell count of L. acidophilus than B. bifidum . On the other hand, no effect of FOS supplementation was reported on the growth of B. infantis in fermented milk (Basholli-Salihu et al 2013 ), B. animalis subsp. lactis in fermented cream cheese (Speranza et al 2018 ) and B. animalis Bb-12 in soymilk (Battistini et al 2018 ).…”

This study aims to investigate the effect of fructooligosaccharide (FOS) (0.5, 1, 2, 3, and 4%) supplementation on the growth and survival of Bifidobacterium breve and Bifidobacterium longum in glucose, fructose, lactose, and sucrose (2, 3, and 4%) systems with 24-h growth and 10-day survival assays at 37 °C. FOS supplementation showed a higher growth-promoting effect on B. longum than B. breve in various sugar systems. The highest percentage of increase in growth index, 78.5%, was observed with 4% sucrose supplemented with 0.5% FOS in B. longum. In comparison, the highest percentage increase in growth index, 5.6 and 6.6%, was observed in the presence of 2% glucose and 4% lactose supplemented with 0.5% FOS in B. breve. In survival assay, FOS supplementation (0.5–4%) in a 2% lactose system showed the highest positive effect on the cell viability of B. longum on day-10. As for B. breve, FOS supplementation (1 and 2%) in the 2% sucrose system showed the highest positive effect on the cell viability, followed by FOS supplementation (0.5, 3, and 4%) in 2% sucrose and FOS supplementation (3 and 4%) in 2% lactose on day-10. This study demonstrated that the efficacy of FOS supplementation was depended on its concentration, sugar system and its concentration, and Bifidobacterium strain.

“…The effect of cellobiose supplementation on the performance, health status, and digestive traits of growing rabbits has been evaluated (Ocasio-Vega et al., 2019 ; Zhong et al., 2019 ). Moreover, Bifidobacterium infantis remains viable during 4 weeks of storage in milk supplemented with cellobiose, suggesting the usefulness of cellobiose as a prebiotic ingredient in fermented products involving bifidobacteria (Basholli-Salihu et al., 2013 ). When cellobiose is ingested by humans, there is no increase in blood glucose or insulin secretion, and orally ingested cellobiose is well fermented in the large intestine (Ruiz-Matute et al., 2011 ).…”

Cellobiose, a natural disaccharide, attracts extensive attention as a potential functional food/feed additive. In this study, we present an inorganic phosphate (Pi) self-sufficient biotransformation system to produce cellobiose by co-expressing sucrose phosphorylase (SP) and cellobiose phosphorylase (CBP). The BASP from Bifidobacterium adolescentis and CGCBP from Cellvibrio gilvus were co-expressed in Escherichia coli. E. coli cells containing BASP and CGCBP were used as whole-cell catalysts to convert sucrose and glucose to cellobiose. The effects of reaction pH, temperature, Pi concentration, and substrate concentration were investigated. In the optimum biotransformation conditions, 800 mM cellobiose was produced from 1.0 M sucrose, 1.0 M glucose, and 50 mM Pi, within 12 h. The byproduct fructose and residual substrate (sucrose and glucose) were efficiently removed by treatment with yeast, to help purify the product cellobiose. The wider applicability of this Pi self-sufficiency strategy was demonstrated in the production of laminaribiose by co-expressing SP and laminaribiose phosphorylase. This study suggests that the Pi self-sufficiency strategy through co-expressing two phosphorylases has the advantage of great flexibility for enhanced production of cellobiose (or laminaribiose).
