bioethanol; biomass; biorefining; capital costs; carbon dioxide; corn; corn stover; ethanol; ethanol production; fermentation; lignin; saccharification
Abstract:
... Corn is the second most abundant crop produced worldwide annually. Its residue, corn stover, is among the three most agricultural residues globally and the first one in the United States. The available corn stover in the world could be used to produce more than 45 million cubic meters of bioethanol (60% of the world production) instead of being mainly burnt on the fields. This practice could poten ...

Abstract:
... Co-fermentation of cellulosic biomass and grain to produce bioethanol has been proposed to integrate first- and second-generation biofuel production technologies. This method can relieve the food versus fuel competition due to the use of edible matter of crop in first-generation biofuel production. It can also boost the low ethanol concentration and thus reduce the unit production cost when using ...

... Utilization of lignocellulose materials to replace the pure glucose for preparation of the fermenting yeast seeds could reduce the cost of ethanol fermentation, because a large quantity of glucose is saved in the large-scale seed fermentor series. In this study, Saccharomyces cerevisiae DQ1 was cultured using the freshly pretreated corn stover material as the carbon source, and then the culture br ...

Abstract:
... Cellulosic ethanol made from cellulosic biomass is an alternative to petroleum-based transportation fuel. The cost-effectiveness of cellulosic ethanol manufacturing has been hindered by several technical barriers. One such barrier is that low density of biomass causes high costs of biomass transportation, handling, and storage. Another barrier is low sugar yield in enzymatic hydrolysis, making enz ...

Abstract:
... Corn stover (cobs and residue) is an important part of the life cycle of corn, either as fuel or as animal feed, but most life cycle analysis (LCA) models treat them separately from starch ethanol. This paper compares four stover and corn grain based ethanol pathways to show how the greenhouse gas (GHG) impacts can differ depending on system boundaries. Corn stover can be used as a cellulosic feed ...

However, xylonic acid (XA) as a new bio-based platform chemical can be produced by oxidation of xylose with microbial. So, an applicable technology of XA bioconversion was integrated into the process of bioethanol production. After corn stover was pretreated with acid-catalyzed steam-explosion, so ...
