“…37,38 Use of RSM for optimization of any method can reduce the number of experiments and thus the time period to evaluate the interactions between many experimental parameters and their different values. 39 Optimization of enzymatic saccharification using RSM was also reported in previous studies. [40][41][42][43] Sopajarn and Sangwichien 44 used CCD in RSM to optimize the cellulase saccharification process in order to obtain high glucose from cattail material (wetland plants) for bioethanol production.…”

“…Messaoudi et al 427 examined the use of an "instant controlled pressure drop" (DIC) pretreatment to improve the enzymatic hydrolysis of eucalyptus chips in relation to ethanol production. The maximum yield of reducing sugars obtained using the DIC pretreatment was ∼85 g reducing sugars/100 g dry feedstock compared to ∼70 g after dilute-acid pretreatment and ∼25 g for the untreated eucalyptus.…”

There is increasing interest in developing biobased alternative jet fuels to meet rising aviation demand and address environmental concerns. Uncertainty of oil prices, issues of energy security, and rising greenhouse gas concentrations have spurred the development and acceptance of alternative, economically viable, environmentally sustainable production pathways. The objectives of this study were to review alternative jet fuel feedstock candidates and relevant conversion data to provide a baseline of information to be accessed and built upon in developing production scenarios in Hawai’i and other tropical regions bounded by the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere. Seventeen plants that produce oil, fiber, and sugar feedstocks were identified, and information on cultural practices, yield ranges, invasiveness, and mechanization status was assembled. Available data on pretreatment requirements and conversion processes for the 17 feedstocks, including mass and energy balances, product and byproduct yield and quality, and scale requirements/unit sizes, were reviewed. This effort seeks to inform the development and design of alternative jet fuel production along regional supply chains in Hawai’i and other locations in the tropics.

“…Even though DIC can be considered a low severity pretreatment regime, it is still expected to contribute some degradation products from glucose and hemicelluloses at treatment temperatures about 170 °C. To avoid producing degradation products, selection of the pretreatment process and its parameters used in the pretreatment and conversion of glucose are very important (Messaoudi et al 2015). DIC pretreatment is also expected to give some chain reactions towards a cleavage of chemical bonding in starch and cellulose superstructure, which then result in the depolymerization into glucose and a polymer with a low degree of oligosaccharides.…”

There is increasing demand for the production of biofuels from lignocellulosic biomass. Lignocellulosic biomass consists mainly of three polymeric components: cellulose, hemicelluloses, and lignin. The separation of these components requires an effective pretreatment process to ensure high quality glucose production, and is highly influenced by several factors, including moisture content, cellulose crystallinity, lignin content, and available surface area. Over time, numerous pretreatment methods have been utilized to change the lignocellulosic fiber structure and to enhance the enzymatic saccharification of cellulose to polysaccharides. This article reviews thermal-based pretreatment of lignocellulosic fiber used for glucose production. Based on the reviewed studies, autohydrolysis of lignocellusic biomass, followed by the “Instant pressure drop (DIC),” method can be regarded as an effective pretreatment process of lignocellusic biomass.
