Influence of oxidation temperature on the gas permeation and separation properties in a microporous carbon membrane
Of thermosetting polymers, polyphenylene oxide (PPO) is considered as one of the promising alternative polymeric precursors for carbon membrane preparation. In this study, the PPO derived carbon membranes were...

Accelerated ethanol fermentation by Saccharomyces cerevisiae with addition of activated carbon
Fermentation with the addition of activated carbon at 100 g l−1 promoted the glucose consumption and ethanol production rates of Saccharomyces cerevisiae by 1.3 and 1.1 times, respectively. With fermentation usin...

Highly concentrated aqueous ethanol solutions by pervaporation using silicalite membrane — Improvement of ethanol selectivity by addition of sugars to ethanol solution
Pervaporation performance using silicalite membranes in the separation of an ethanol/water solution was affected by the addition of sugars, sugar alcohols or yeast cells. Although the membrane flux drastically...

Polymeric Membranes for Separation
Membrane separation is a type of filtration for fine particles including molecules or ions. The driving force for the separation is mainly the pressure difference between the two sides of a membrane. In operat...

Contribution of a chain-shortening pathway to the biosynthesis of the fatty acids of mannosylerythritol lipid (biosurfactant) in the yeast Candida antarctica: Effect of β-oxidation inhibitors on biosurfactant synthesis
Inhibitors of β-oxidation on the synthesis of glycolipid biosurfactant, mannosylerythritol lipid (MEL), were used to clarify the fatty acid metabolism of MEL in Candida antarctica. 2-Bromooctanoic acid drastic...

One-step separation of phospholipids from triacyglycerols with asymmetric polyimide membrane in organic solution
Convenient separation of a mixture of neutral and complex lipids was achieved by using an asymmetric polyimide membrane (M.W. cut-off : 35,000Da) with a high solvent-resistance prepared by a phase inversion pr...

Effect of cerulenin on the production of mannosyl-erythritol lipids as biosurfactants by Candida antarctica
The effect of cerulenin, anti-lipogenic antibiotic, on the production and fatty-acid profiles of biosurfactants (mannosyl-erythritol lipids) of Candida antarctica were investigated by changing the chain-length of...
