Bioconversion of corn fiber to bioethanol: Status and perspectives

Engineering All-Round Cellulase for Bioethanol Production

“…In first-generation (1G) bioethanol, the fiber in starch feedstock like corn is not utilized but recovered as a byproduct . By integrating cellulases into fiber degradation, our previous work developed a technology called ADISET to fully use corn components with increasing bioethanol yield and valorization of underutilized biomass. , Also, second-generation (2G) bioethanol made from lignocellulosic biomass preferred to employ enzymatic hydrolysis to overcome several drawbacks in acid hydrolysis, such as nonselectivity, byproduct formation, low ethanol yields, and the high cost of wastewater treatment. ,, And efficient degradation of lignocellulosic biomass required a synergistic action of several cellulases and hemicellulases .…”

Besides the aforementioned product inhibition, the practical stability in fermentation conditions was the actual property that bioethanol engineers are looking for. ,, Among various pretreatment methods used in 2G bioethanol, organic solvent pretreatment was a promising strategy, which can remove lignin and depolymerize cellulose to form short fibers. , For instance, total sugar conversion and feasibility of using dimethyl sulfoxide (DMSO) for white poplar and pine pretreatment depended on DMSO concentration .…”

Utilizing Undissolved Portion (UNP) of Cement Kiln Dust as a Versatile Multicomponent Catalyst for Bioethylene Production from Bioethanol: An Innovative Approach to Address the Energy Crisis

“…Gaseous or liquid fuels that are primarily derived from biomass are generally referred to as "biofuels". 19 In particular, bioethanol, produced from various substrates, 20 is becoming more widely available as a feedstock, and thus it was utilized in various processes, such as hydrogen, ethylene, and diethyl ether (DEE) production. Ethylene production is a mature technology in the energy sector, and the demand for renewable ethylene is steadily increasing due to economic growth, with the ethylene market growing by approximately 4% annually.…”

Isolation and Extraction of Monomers from Insoluble Dietary Fiber

“…It is also used in the production of meat products to obtain high-dietary fiber, low-calorie, low-fat products; it can make the meat taste richer [ 14 ]. Developing economically viable and sustainable technologies for converting corn fiber into liquid fuels is widely seen as a promising approach to achieve improved ethanol titers and integrated utilization of byproducts in the traditional corn dry milling process [ 15 ].…”
