Increase in bioethanol production from used office paper by Saccharomyces cerevisiae UFPEDA 1238
نویسندگان
چکیده
Background Used paper is particularly attractive as feedstock for bioethanol production because it is readily available [1]. The aim this work was to hydrolyze used office paper with dilute sulfuric acid for bioethanol production by three industrial strains of Saccharomyces cerevisiae. Acid concentration, time of the hydrolyze and ratio solid: liquid were varying according to factorial design. Reaction time was not significant. Maximum total reducing sugar content was obtained with 5 % V/V acid concentration and 1:10 ratio solid-liquid. Higher ethanol production was obtained by UFPEDA 1238 in 24 h. Increase 7 to 47 % was obtained in ethanol production, when S. cerevisiae UFPEDA 1238 was used in relation to other two strains.

Enhanced Bioethanol Production in Batch Fermentation by Pervaporation Using a PDMS Membrane Bioreactor
The integration of batch fermentation and membrane-based pervaporation process in a membrane bioreactor (MBR) was studied to enhance bioethanol production compared to conventional batch fermentation operated at optimum condition. For this purpose, a laboratory-scale MBR system was designed and fabricated. Dense hydrophobic Polydimethylsiloxane (PDMS) membrane was used for pervaporation. For fer...

Broomcorn seed (Sorghum vulgare) was used as raw material for bioethanol production. Optimum conditions were obtained from response surface method. Broomcorn seed flour (45 g/l) was treated by alkaline treatment and dual enzymatic hydrolysis (0.7 g/l of α- amylase and 0.42 g/l of amyloglucosidase). The hydrolyzed total sugar of 25.5 g/L was used in conventional bioethanol production (8.1 g/l) u...

A thermophilic strain AMF-07, hydrolyzing carboxymethylcellulose (CMC) was isolated from Kerman hot spring and was identified as Bacillus licheniformis based on 16S rRNA sequence homology. The carboxymethylcellulase (CMCase) enzyme produced by the B. licheniformis was purified by (NH4)2SO4 precipitation, ion exchange and gel filtration chromatography. The purified enzyme gave a single band on S...
