The purpose of this study was to produce microbial oil from Yarrowia lipolytica Po1g grown in defatted rice bran hydrolysate. After removing oil from rice bran by Soxhlet extraction, the bran is subjected to acid hydrolysis with various sulfuric acid concentrations (1-4% v/v), reaction times (1-8 h), and reaction temperatures (60-120°C). The optimal conditions for maximum total sugar production...

The application of thermal pretreatments to facilitate its anaerobic digestion has associated phenols and furans production, which are commonly identified as inhibitory compounds. Phenols extraction can be done from a liquid phase produced after the pretreatment. In present study this dephenolized (DLP) showed an increase 42% in methane yield compared raw (LP) demonstrating inhibitor character ...

Bamboo is a potential lignocellulosic biomass for the production of bioethanol because of its high cellulose and hemicellulose contents. An acid-free ethanosolv process was proposed to overcome the problems caused by the acid catalysts commonly used in organosolv processes. In this research, ethanosolv pretreatment catalyzed by NaOH was used to enhance the enzymatic saccharification of moso bam...

Recently, Kwon et al. reported that the antioxidant activity and total both polyphenol and flavonoid contents of garlic juice were increased by high temperatureand pressure-treatment (130°C, 120 min). We tried to make high temperatureand pressure-treated garlic (HTPG) using an autoclave (130°C, 150 min) rapidly and easily. Our attempt showed that antioxidative activity and total polyphenol cont...

In this study, a simple and green protocol to obtain hydrochar high-added value products, mainly 5-hydroxymethylfurfural (5-HMF), furfural (FU), levulinic acid (LA) alkyl levulinates, by using the hydrothermal carbonization (HTC) of orange peel waste (OPW) is presented. Process variables, such as reaction temperature (180–300 °C), time (60–300 min), biomass:water ratio initial pH were investiga...

Effective lactic acid (LA) production from lignocellulosic biomass materials is challenged by several limitations related to pentose sugar utilization, inhibitory compounds, and/or fermentation conditions. In this study, a newly isolated Bacillus coagulans strain Azu-10 was obtained and showed homofermentative LA xylose with optimal conditions at 50 °C pH 7.0. Growth of LA-fermentation efficien...
