Over the years, ethanol has attracted global interest as a renewable and clean liquid fuel. Currently, feedstocks for commercial fuel ethanol production include cereal grains (e.g., corn, wheat, barley, cassava) and sugar crops (e.g., sugarcane, sugar beets, sweet sorghum). Sugarcane and corn are the two feedstocks that have been used most extensively. Despite the commercial success, relentless research efforts have been made to improve the economics of ethanol production through increase of ethanol yield and development of value-added co-products. Some of these efforts have reached commercialization, for example, the extraction of corn oil and the implementation of the D3MAX process for additional ethanol yield from corn fibers at many corn ethanol plants. Production of biogas from the wastes generated in the ethanol production process to provide an energy source for internal uses also has been practiced at commercial scale.
Lignocellulosic biomass recently attracted interest as an alternate potential feedstock for ethanol production mainly because of its availability in large quantities. Research has been performed to develop process technologies for conversion of biomass to ethanol via either the sugar platform or the syngas platform. Several of these processes have been demonstrated at pilot and semi-commercial scales. Industrial chemicals and consumer products that can be made from C5 sugars and lignin have been considered as potential high value-added co-products of cellulosic ethanol.
The goal of this Special Issue is to publish both recent innovative research results, as well as review papers on the production of ethanol and value-added co-products from sugar-based, starch-based and cellulosic biomass feedstocks by biochemical processes. Review and research papers on development of novel enzymes and microbial strains are also of interest. If you would like to contribute a review paper, please contact one of the editors to discuss the topic relevance before submitting the manuscript.

Title: Techno-economic bottlenecks of fungal pretreatment of lignocellulosic biomass.
Author: Ajay Shah
Abstract: Fungal pretreatment is an alternative biomass pretreatment process that uses rotting fungi to enhance the digestibility of lignocellulosic feedstocks. Fungal pretreatment is performed at low temperature, without added chemicals and no wastewater generation; however, it requires long incubation times and generates lower yields than traditional pretreatments. Because of its simplicity, fungal pretreatment has been described previously as a low-cost process, but no studies have evaluated the techno-economic feasibility of this pretreatment at commercial scale, and the possible bottlenecks of the process. Process modeling and techno-economic analysis of fungal pretreatment of lignocellulosic biomass would allow to identify the main bottlenecks of the fungal pretreatment process to help canalize development resources in order to improve the feasibility of this technology. In this work, we developed a process model of a fungal pretreatment-based cellulosic biorefinery with a 30-million gallons ethanol/year capacity. Experimental data from literature was used as input, accounting for variation in conditions and yields of fungal pretreatment, and different kinds of feedstocks were considered. Additionally, the effect of the variation of process parameters on the production cost were evaluated with sensitivity analysis.
