The biological process route of xylitol production from lignocellulosic materials, via enzymatic hydrolysis which is followed by fermentation, offers a more sustainable or greener process than the chemical process route. Both the enzymatic hydrolysis and the fermentation processes are conducted at moderate process condition and thus require less energy and chemicals. However, the process proceeds slower than the chemical one. In order to improve process performance, the enzymatic hydrolysis and the fermentation processes can be integrated as Simultaneous Saccharification and Fermentation (SSF) configuration. This paper discusses the evaluation of SSF configuration on xylitol production from Oil Palm Empty Fruit Bunches (OPEFB). To integrate two processes which have different optimum temperature, the performance of each process at various temperature was first evaluated. Later, SSF was evaluated at various hydrolysis and fermentation time at each optimum temperature. SSF showed better process performance than the separated hydrolysis and fermentation processes. The best result was obtained from configuration with 72 hours of prior hydrolysis followed by simultaneous hydrolysis and fermentation, giving yield of 0.08 g-xylitol/g-OPEFB.

“…The diluted hydrolyzed samples were conditioned to temperature of 30 °C before fermentation step is started. This was the temperature at which all fermentation experiments were carried out [24] . (C 6 H 10 O 5 ) n + n(H 2 O) → nC 6 H 12 O 6 (C 5 H 8 O 4 ) n + n(H 2 O) → nC 5 H 10 O 5 …”

“…Industrially, acid hydrolysis, particularly dilute-acid hydrolysis, is the most commonly employed method owing to its efficiency in hydrolyzing hemicellulose at a fast rate at less cost (Martin et al, 2013). Moraes et al (2020) have obtained 99% extraction of xylose by pretreating the biomass with 1% sulphuric acid at 120 • C. The use of nitric acid hydrolysis has been found to improve xylose extraction (Dalli et al, 2017b;Manaf et al, 2018;Shah et al, 2020). Acid pretreatment releases monomeric sugars from the hemicellulose thereby eliminating the need for a further hydrolysis step.…”

Xylitol, a natural compound classified as a sugar alcohol, is found diversely in fruits and vegetables in small quantities. Commercial production of xylitol has expanded due to its health benefits and wide applications as an alternative sweetener in food and pharmaceutical products. Production of xylitol on large scale is industrially being achieved by the chemical method. However, the biotechnological method offers the possibilities of lowered cost and energy compared to the chemical methods. It involves the conversion of xylose to xylitol by microbes or enzymes which is environmentally safe. This review highlights the prospects of the biotechnological method of xylitol production. Various microorganisms that have been used to produce xylitol, the bioprocess parameters, and genetic modifications to increase xylitol yield have been reviewed. In addition, the applications, benefits, and safety concerns to health have been discussed.
