Conditions that Promote Production of Lactic Acid by Zymomonas mobilis in Batch and Continuous Cultin their steady-state growth environment. The usual high degree of ethanol selectivity associated with glucose fermentation by Z. . is associated with conditions that promote rapid and robust growth, with about 95% of the substrate (5% w/v glucose) being converted to ethanol and CO., and the remaini

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

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

Pretreatment conditions for the Sunds hydrolyzer, installed in the NREL process development unit (PDU), which operates at 1 t/d (bone-dry t) feed rate, spanned the temperature range of 160-210°C, 0.1-1.0% (w

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
