Rice straw has recently attracted interest in Japan as a potential source of raw material for ethanol production. Wet disk milling, a continuous pretreatment to enhance the enzymatic digestibility of rice straw, was compared with conventional ball milling and hot-compressed water treatment. Pretreated rice straw was evaluated by enzymatic hydrolysis using(More)
An energy efficient nanofibrillation method that combines disk milling and mild hot-compressed water (HCW) treatment was developed to improve enzymatic accessibility of Eucalyptus wood. In this method, the residual product of HCW treatment was fibrillated by disk milling under wet conditions. Relatively moderate HCW treatment conditions (temperature below(More)
The hydrocarbon-rich green microalga, Botryococcus braunii, was grown on secondarily treated sewage (STS) in a continuous bioreactor system. The algal biomass increased at a sustained rate of 196 mg dry weight/l per week for 1 month. The hydrocarbon content of algae grown on STS (49%) compared well with that of algae grown on an artificial medium. The(More)
Ozonolysis and subsequent wet-disk milling (DM) were carried out on Japanese cedar (Cryptomeria japonica) to improve sugar production by enzymatic saccharification. When the moisture content reached more than 40%, ozone consumption decreased, resulting in less delignification. Ozone treatment removed mainly lignin, but also small amounts of polysaccharides.(More)
Hot-compressed water (HCW) is among several cost-effective pretreatment processes of lignocellulosic biomass for enzymatic hydrolysis. The present work investigated the characteristics of HCW pretreatment of rice straw including sugar production and inhibitor formation in the liquid fraction and enzymatic hydrolysis of pretreated material. Pretreatment was(More)
Dilute-alkali-catalyzed hydrothermal treatment (HT) was conducted to improve the enzymatic degradability of sugarcane bagasse. Wet-disk milling (DM) was also performed after HT. Sodium carbonate with 0-6% concentration on dry weight basis of bagasse was used as the alkali catalyst. A content of more than 4% of the alkali catalyst was necessary for producing(More)
Pretreatment-induced structural alteration is critical in influencing the rate and extent of enzymatic saccharification of lignocellulosic biomass. The present work has investigated structural features of rice straw pretreated by hot-compressed water (HCW) from 140 to 240 °C for 10 or 30 min and enzymatic hydrolysis profiles of pretreated rice straw.(More)
Phototrophic bacterial cells in the effluent from a lighted upflow anaerobic sludge blanket reactor supplied with a medium containing 142 mg S (as SO4 2−) l−1 accumulated a 6.8% w/w oleic acid content in cells and 19 mg cell-bound oleic acid l−1 in the effluent. Pure cultures of Rhodopseudomonas palustris and Blastochloris sulfoviridis isolated from the(More)
The organic compositions of the liquid phase separated from liquidized garbage as the influent and its effluent after anaerobic digestion at an overloading rate were analyzed. A large amount of organic acids was found in the effluent. The accumulation of organic acids suggests that the rate of methanogenesis is lower than that of acidogenesis.
