Yellow Top (Physaria fendleri) is a plant that belongs to the mustard family. This plant is used to produce seeds that are rich in hydroxy oil. After extraction of oil, the presscake is land filled. The seedcake is rich in polymeric sugars and can be used for various bioconversions. For the present case, the seedcake or presscake was hydrolyzed with dilute (0.50% [v/v]) H 2 SO 4 and enzymes to release sugars including glucose, xylose, galactose, arabinose, and mannose. Then, the hydrolyzate was used to produce acetone-butanol-ethanol (ABE). Using 100 gL −1 presscake (prior to pretreatment), 19.22 gL −1 of ABE was successfully produced of which butanol was the major product. In this process, an ABE productivity of 0.48 gL −1 h −1 was obtained. These results are superior to glucose fermentation to produce ABE in which an ABE productivity of 0.42 gL −1 h −1 was obtained. Use of Yellow Top to produce butanol has the following advantages: (i) it is an economic feedstock and is expected to produce butanol economically; (ii) it avoids pollution concerns when not land filled; and (iii) rate of ABE production is not inhibited when fermented this substrate. It is suggested that the potential of this feedstock be further explored by optimizing process parameters for this valuable fermentation.

Four different processes for butanol production from corn, namely, batch fermentation and distillative recovery (BFDR), batch fermentation and pervaporative recovery (BFPR), fed-batch fermentation and pervaporative recovery (FBFPR), and immobilized cell continuous fermentation and pervaporative recovery (ICCFPR) were evaluated. Pervaporative recovery signi®cantly reduces the cost of butanol production. Depending upon the byproduct credit, which is approximately 3.7 times that of the amount of butanol produced, BFDR, BFPR, FBFPR, and ICCFPR result in a butanol price of $0.55, $0.14±0.39, $0.12±0.37, and $0.11±0.36´kg ±1 , respectively. The price of butanol was recently reported at $1.21´kg ±1 by Chemical Marketing Reporter. It should be noted that all three components (acetone, butanol, and ethanol: ABE) diffuse through the pervaporation membrane. Further separation and puri®cation of the solvents would require distillation, which has been considered in this exercise. This article also details the impact of byproduct credit, rate of return, and tax on butanol price.

“…Besides producing ethanol, cellulosic ethanol plants produce co-products (such as hydrogen, natural gas and animal feed protein [29][30][31][38][39][40]49,56,57]). The type and amount of coproducts are determined by the technologies and process configurations used in cellulosic ethanol production [29][30][31].…”

Increasing demands and concerns for reliable supply of liquid transportation fuels make it important to find alternatives to petroleum-based f'uels. One such alternative is ethanoi made from cellulosic biomass. Considerable investigations have been conducted to evaluate the viability of cellulosic ethanol production in several aspects (including cost competitiveness). Cost estimates of cellulosic ethanol production have been reported by many researchers in order to evaluate the economic viability of cellulosic ethanol production. However, the reported cost estimates in the literature have a large variation. The current literature contains iimited reviews on the cost estimates of cellulosic ethanol production and mostly focused on some individuai processes. This paper presents a literature review on the cost estimates of entire cellulosic ethanol production. It reviews the estimated costs for both the entire cycle (from planting to conversion) and individual processes for cellulosic ethanol production. It also covers factors that lead to variations among reported cost estimates.
