“…The semidry acid hydrolysis of the cheap and abundant cellulosic wastes feedstock might possibly be applicable not only for bacterial H 2 production but also for other cellulose dependent biotechnologies.

Cellulosic biowastes are one of the cheapest and most abundant renewable organic materials on earth that can be, subsequent to hydrolysis, utilized as an organic carbon source for several fermentation biotechnologies. This study was devoted to explore a semidry acid hydrolysis of cellulose for decreasing the cost and ionic strength of the hydrolysate. For semidry acid hydrolysis, cellulose was just wetted with HCl (0 to 7 M) and subjected to autoclaving. The optimum molar concentration of HCl and period of autoclaving for semidry acid hydrolysis of cellulose were 6 M and 50 min respectively. Subsequent to the semidry acid hydrolysis with a minimum volume of 6 M HCl sustained by autoclaving, the hydrolysate was diluted with distilled water and neutralized with NaOH (0.5 M). The reducing sugars produced from the semidry acid hydrolysis of cellulose was further used for dark fermentation biohydrogen production by Escherichia coli as a representative of most hydrogen producing eubacteria which cannot utilize non-hydrolyzed cellulose. An isolated E. coli TFYM was used where this bacterium was morphologically and biochemically characterized and further identified by phylogenetic 16S rRNA encoding gene sequence analysis. The reducing sugars produced by semidry acid hydrolysis could be efficiently utilized by E. coli producing 0.4 mol H2 mol−1 hexose with a maximum rate of hydrogen gas production of 23.3 ml H2 h−1 L−1 and an estimated hydrogen yield of 20.5 (L H2 kg−1 dry biomass). The cheap cellulosic biowastes of wheat bran, sawdust and sugarcane bagasse could be hydrolyzed by semidry acid hydrolysis where the estimated hydrogen yield per kg of its dry biomass were 36, 18 and 32 (L H2 kg−1 dry biomass) respectively indicating a good feasibility of hydrogen production from reducing sugars prepared by semidry acid hydrolysis of these cellulosic biowastes. Semidry acid hydrolysis could also be effectively used for hydrolyzing non-cellulosic polysaccharides of dry cyanobacterial biomass. The described semidry acid hydrolysis of cellulosic biowastes in this study might be applicable not only for bacterial biohydrogen production but also for various hydrolyzed cellulose-based fermentation biotechnologies.

“…Wet sugarcane plant contains roughly 36% juice and 64% residue (30% bagasse and 34% straw and leaves), and the latter contains 50% and 10% moisture, respectively ( Ferreira-Leitão et al, 2010 ; Aruna et al, 2021 ; Agarwal et al, 2022 ). The large amount of co-produced sugarcane bagasse (SCB), on the one hand, poses great challenge to processing industries and environment, and on the other hand, might be better utilized as a cheap source to produce value-added products, for example, enzymes, reducing sugars, prebiotic, organic acids, and biofuels ( Alokika et al, 2021 ). For this reason, much attention has been paid in finding effective ways to reuse SCB ( Chen et al, 2017 ).…”

Following juice crushing for sugar or bioethanol production from sugarcane, bagasse (SCB) is generated as the main lignocellulosic by-product. This study utilized SCB generated by a hydraulic press as feedstock to evaluate sugar extraction as well as adsorption potential. Total soluble sugar (sucrose, glucose, and fructose) of 0.4 g/g SCB was recovered with H2O extraction in this case. Insoluble sugar, that is, cellulose in SCB, was further hydrolyzed into glucose (2%–31%) with cellulase enzyme, generating a new bagasse residue (SCBE). Persulfate pretreatment of SCB slightly enhanced saccharification. Both SCB and SCBE showed great potential as adsorbents with 98% of methylene blue (MB) removed by SCB or SCBE and 75% of Cu2+ by SCBE and 80% by SCB in 60 min. The maximum adsorption amount (qm) was 85.8 mg/g (MB by SCB), 77.5 mg/g (MB by SCBE), 3.4 mg/g (Cu2+ by SCB), and 1.2 mg/g (Cu2+ by SCBE). The thermodynamics indicated that the adsorption process is spontaneous, endothermic, and more random in nature. The experimental results offer an alternative to better reutilize SCB.

“…Approximately 54 million tons of SCB are produced annually worldwide (Zhou & Xu, 2019b). Most of this waste is used to feed boilers in energy supply industries (Carvalho, Neto, Da Silva, & Pastore, 2013) and ethanol production (Alokika, Kumar, Kumar, & Singh, 2021). However, due to its composition rich in hemicellulose (24-29%), several studies have shown that SCB is a promising raw material for the production of XOS (Brienzo, Carvalho, & Milagres, 2010;Otieno & Ahring, 2012).…”

Hydrothermal processing is an organic solvent-free technology capable of solubilizing hemicellulose in oligomers of interest. This study evaluated the influence of pressure (2.5 and 10 MPa) on the release of the main components of sugarcane bagasse (SCB) as reducing sugars, phenolic compounds and xylooligosaccharides (XOS) during hydrothermal treatment in a continuous flow mode for 30 min. The study carried out at 180 C showed that 85% of the sugar extraction capacity was reached after 15 min at both pressures. The evolution of pH, phenolic compounds released in the liquor and small changes in the lignocellulosic structure were also monitored and related to the effects of hydrothermal treatment. The xylose content was similar at both pressures (22 mg/g xylan), while the XOS (X2-X6) yield was 87.5 and 111.4 mg/g xylan at 2.5 and 10 MPa, respectively. A mass balance was used to estimate that 6.76 kg of XOS could be produced from 100 kg of SCB treated at 180 C, 2.5 MPa, and 15 min.
