“…Ultrasonication invades and disrupts the cell wall integrity by creating cavitation phenomenon followed by generation of microbubbles and shear forces along with cleaving of ether bonds present in between hemicellulose and lignin resulting in increased accessibility and extractability of xylan [30]. Ultrasonication can accelerate the time to reach the equilibrium concentration and thereby reducing extraction time [31]. Hence, the non- (1:38.55), hence conforming its validity.…”

“…Sun et al[29] reported increase in xylan extraction efficiency from corncob with the increase in corncob to alkali solution ratio from 1:10 to 1:30.Ultrasonication invades and disrupts the cell wall integrity by creating cavitation phenomenon followed by generation of microbubbles and shear forces along with cleaving of ether bonds present in between hemicellulose and lignin resulting in increased accessibility and extractability of xylan[30]. Ultrasonication can accelerate the time to reach the equilibrium concentration and thereby reducing extraction time[31]. Hence, the nonsignificant effect of ultrasonication time (10-40 min) on the xylan recovery was due to acceleration of time to reach the equilibrium concentration leading to lesser xylan recovery with the extension of ultrasonication time[32].Based on the desirability function of Design Expert, the experimental xylan recovery value (11.89% w/w) was observed to be similar to predicted maximum xylan recovery(12.059 %) at NaOH concentration (0.73 M), ultrasonication time (34.77) min and solid to liquid ratio…”

This study focused on the optimization of xylitol production from sugarcane bagasse by using response surface methodology (RSM). Xylitol was produced through a series of processes, firstly, optimization of ultrasound assisted mild alkaline pretreatment for the xylan extraction from sugarcane bagasse followed by enzymatic hydrolysis of xylan to xylose by enzyme β-1,4-xylanase and finally microbial fermentation of xylose to xylitol using yeast (Candida guilliermondii), bacteria (Corynebacterium glutamicum) and their mixed culture for different time periods (0-96 h). Maximum xylan recovery of 12.059% (w/w) was observed at pretreatment; 0.73 M NaOH, 1:38.55 solid to liquid ratio and 34.77 min ultrasonication. The enzyme concentration of 400 U/g xylan at 48 h of incubation showed the highest xylose production (81.51 mg/g bagasse). Yeast (Candida guilliermondii) resulted in the highest xylitol yield (Yp/s= 0.43 g/g) after 72 h. This bioprocess route can contribute as a suitable alternative for chemical methods of xylitol production.

“…Besides grains, cassava, a root tuber, is another important starchy biomass. All these starchy materials have been cultivated all over the world and used as important feedstock in biotechnological processes, such as for the production of ethanol (Bayitse et al, 2015) and various other bioproducts (Martiniano et al, 2014(Martiniano et al, , 2016Arruda et al, 2017;Lee et al, 2017).…”

The integrated approach in biorefinery mainly involves the utilization of various agroindustrial byproducts such as raw materials for the production of several biobased products like biofuels, bioenergy, and other high-value chemicals. Biofuels are the backbone of biorefineries, however, production of value-added biomolecules such as biopigments, biopolymers, biosurfactants, and nutritional yeast has been attracting great attention. The production of these biomolecules using traditional approaches has been extensively studied in the last few years owing to their promising application in different industries such as chemical, food/feed, and pharmaceuticals for the development of novel products for mankind. Moreover, the production of such biomolecules using lignocellulosic, starchy, and some other agroindustrial byproducts is still not fully explored. Hence, there is a huge scope in the development of sustainable biorefining approaches to make the technology cost-effective. The lignocellulosic biomasses usually used in biorefineries are mainly composed of cellulose, hemicellulose, and lignin, whereas starchy materials, besides starch, usually contain, protein, lipids, and some micronutrients. The processing of these biomasses through successive steps like pretreatments, enzymatic hydrolysis, and fermentation is essentially required to obtained final biobased products. Considering certain bottlenecks of above-mentioned conventional biorefineries approaches, new technologies have been proposed for the improved pretreatment of biomass and efficient enzymatic hydrolysis in order to minimize the concentration of toxic inhibitors in resulting hydrolysate. In this review, we highlighted the different agroindustrial byproducts and their applications for the production of valuable biorefinery products.

“…At first, the lignocellulosic biomass was considered a source of glucose for ethanol production by fermentation. However, according to the biorefinery concept, the lignocellulosic biomass is now considered a raw material for many different industrial processes [9]. The industrial application of non-cellulose (hemicellulose and lignin) fractions are also a target in recent studies.…”

Lignocellulosic materials require pretreatment to remove lignin enabling the enzyme access to the cellulose. This work used multivariate analysis to investigate the acid and alkali pretreatments of vine pruning followed by enzymatic hydrolysis. The best acid pretreatment conditions were H 2 SO 4 1.5%, 120 � C for 30 min, removing 68.7% of hemicellulose, enabling 95.8% of cellulose recovery. However, this treatment was not enough to allow the enzyme hydrolysis. A second step of treatment with NaOH 3.0% at 120 � C without agitation for 60 min led to a material with 75.0% of cellulose and 25.0% of lignin. However, the lowest glucose yield (80.86% and 32.26 g L À 1 of glucose) was obtained after the enzyme hydrolysis of this material. The highest glucose yield (98.72% with 35.06 g L À 1) was obtained using a pretreated material containing 68.1% of cellulose and 31.9% of lignin obtained after a milder condition (NaOH 2% at 100 � C), thus showing that not all the lignin need to be removed to obtain a high saccharification yield. A less severe pretreatment with no adverse effect on the glucose yield with the advantage of preserving the non-cellulose biomass fractions was effective for vine prune valorization.
