The isoflavonol glycoside Talosin A, genistein (GT)-7-a-L-6- deoxy talopyranose (GT-Tal), was first isolated from the culture broth of Kitasatospora kifunensis MJM341. The aim of the present study was to evaluate the oral absorption and metabolism of the newly isolated isoflavonol glycoside, GT-Tal compared to genistin (GT-7-O-b-D-glucopyranoside; GT- Glu). Free GT-Glu and GT-Tal could not be detected prior to enzymatic hydrolysis of the corresponding conjugates in rat plasma. Following oral... -

Bacterial leaf blight is a major disease of eucalypt, especially under nursery conditions. Different bacterial species have been associated with the disease in several countries, and despite its importance worldwide, it is not clear to date whether similar disease symptoms are caused by the same or by different etiological agents. In this study, 43 bacterial strains were isolated from blighted eucalypt leaves collected in different geographic areas of Brazil and inoculated onto a susceptible... -

한국식물병리학회 The Plant Pathology Journal 2013, 29권 2호 4 144-153 (10 pages)
a small fraction of that diversity has been evaluated for their biopesticide potential. To date, the criteria for sampling and selection in such bioprospecting endeavors have not been systematically evaluated in terms of the relative amount of diversity they provide for analysis. The present study aimed to enhance the success of bioprospecting efforts by increasing the diversity while removing the genotypic redundancy often present in large collections of bacteria. We developed a multivariate... -

Today, finding superior methods for synthesis of graphene oxide (GO) and reduced graphene oxide (rGO) from commercial graphite, is still a challenge. The global industry requires the use of synthesis methods that are price-competitive and also use processes that are environmentally compatible. GO is a substrate used for several chemical transformations, including its reduction to related materials, such as rGO and graphene. The rGO has been used recently to increase catalytic activity in the... -
An overview of new oxidation methods for polyacrylonitrile?based carbon fibers
Hye Kyoung Shin, Mira Park, Hak-Yong Kim and Soo-Jin Park 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.1 2 11-18 (8 pages)
The process of oxidizing polyacrylonitrile (PAN)-based carbon fibers converts them into an infusible and non-flammable state prior to carbonization. This represents one of the most important stages in determining the mechanical properties of the final carbon fibers, but the most commonly used methods, such as thermal treatment (200°C to 300°C), tend to waste a great deal of process time, money, and energy. There is therefore a need to develop more advanced oxidation methods for PAN precursor... -

Effect of nitrogen-load condition on hydrogen (H2) production and bacterial community in a continuous anaerobic hydrogen fermentation were investigated. The slight H2 production on extremely low nitrogen-load condition (C/N ratio: 180) at the start-up period. The highest H2 production was obtained when the C/N ratio was 36, the H2 production yield (mol-H2 / mol-glucose) reached to 1.7, and it was indicated that Clostridium pasteurianum mainly contributed to the H2 production. The H2 production...
