Abstract:
... A strain of Saccharomyces cerevisiae, KCCM50549, was found to efficiently ferment the inulin-containing carbohydrates in Jerusalem artichoke without acidic or enzymatic pretreatment prior to fermentation. S. cerevisiae KCCM50549 could utilize almost completely the fructo-oligosaccharides present in Jerusalem artichoke (up to degree of polymerization (DP) of 15), in contrast to the other S. cerevis ...

Abstract:
... Lactic acid fermentation of Jerusalem artichoke tuber was performed with strains of Lactobacillus paracasei without acidic or enzymatic inulin hydrolysis prior to fermentation. Some strains of L. paracasei, notably KCTC13090 and KCTC13169, could ferment hot-water extract of Jerusalem artichoke tuber more efficiently compared with other Lactobacillus spp. such as L. casei type strain KCTC3109. The ...

Abstract:
... In this study, the influence of powdered activated carbon (PAC) and cationic polymer (MPE50) was investigated on the fouling propensity in hybrid MBRs. Three laboratory scale MBRs were operated simultaneously including MBRCₒₙₜᵣₒₗ, MBRPAC, and MBRPₒₗyₘₑᵣ. Optimum dosages of PAC and polymer to the MBRPAC and MBRPₒₗyₘₑᵣ, respectively were determined using jar tests. It was found that the MBRPAC exhib ...

Abstract:
... The freshwater microalga, Hydrodictyon reticulum, that contained 47.5% reducing sugars including 35% glucose was used as substrate for the production of l-lactic acid (LA) by LA-producing bacteria. Lactobacillus paracasei LA104 was selected for fermentation in a 5-l fermentor since it was able to grow at pH 3, 60g LA/l, 200g glucose/l, 125g NaCl/l, and 45°C and produced over 97.3% optically pure l ...

Abstract:
... Pseudomonas fulva TY16 biosynthesized medium-chain-length poly(3-hydroxyalkanoates) (MCL-PHAs) containing unsaturated 3-hydroxydodecenoate unit (approximately 8-9%) when grown with volatile aromatic compounds including benzene, toluene, and ethylbenzene as sole carbon substrate. In particular, when cultivated using a continuous feeding system designed to supply toluene at a flow rate of 0.42gL⁻¹ h ...

Abstract:
... The effect of cationic polymer additives on biomass granulation and COD removal efficiency had been examined in lab-scale upflow anaerobic sludge blanket (UASB) reactors, treating low strength synthetic wastewater (COD 300-630mg/l). Under identical conditions, two reactors were operated with and without polymer additives in inoculum under four different organic loading rates (OLRs). The optimum po ...
