Improving Fermentation Performance of Recombinant Zymomonas in Acetic Acid-Containing Media, glucose, with varying amounts of acetic acid was examine. To minimize the concentration of the inhibitory undissociated form of acetic acid, the pH was controlled at 6.0. The final cell mass concentration decreased linearly with increasing level of acetic acid over the range 0-0.75% (w/v), with a 5

Feedstock Supply and Processing,of obtaining fuel additives and oxygenated chemicals from biomass. This series of papers examines biomass feedstock availability, and the impact of advances in hydrolysis and pretreatment methods on improving extents of conversion of cellulose to glucose. Significant progress has been made, but the

Pretreatment of Softwood by Acid-Catalyzed Steam Explosion Followed by Alkali Extraction, acid- or enzyme-catalyzed hydrolysis of the cellulosic fraction. Enzymatic hydrolysis may be improved by using an alkali to extract a fraction of the lignin from the pretreated material. The removal of the lignin may increase the accessibility of the cellulose to enzymatic attack, and thus improve

Shrinking-Bed Model for Percolation Process Applied to Dilute-Acid Pretreatment/Hydrolysis of Cellulated two-stage reverse-flow. This process has been proven to attain substantially higher sugar yields and concentrations over the conventional single-stage percolation process. The dilute-acid pretreatment of biomass solubilizes the hemicellulose fraction in the solid biomass, leaving less solid bi

Cost Estimates and Sensitivity Analyses for the Ammonia Fiber Explosion Process,s were estimated. AFEX costs about $20-40/t of dry biomass treated. Several promising areas for reducing process costs exist. Return on investment (ROI) calculations were also done for AFEX-treated materials (as digestibility-enhanced animal feeds), in conjunction with sensitivity analyses on the ov
