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... -
Sampling and Selection Factors that Enhance the Diversity of Microbial Collections: Application to Biopesticide Development
한국식물병리학회 The Plant Pathology Journal 10 Pages
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... -
Production of a Phytotoxic Compound, 3-Phenylpropionic Acid by a Bacterial Endophyte, Arthrobacter humicola YC6002 Isolated from the Root of Zoysia japonica
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 3호 6 245-252 (8 pages)
An endophytic bacterial strain, Arthrobacter humicola YC6002, was isolated from a surface sterilized root of Korean turf grass (Zoysia japonica) collected from Jinju, Korea. This strain showed inhibitory effect on germination and shoot growth of radish. The inhibition of germination and shoot growth of radish seeds varied depending on the age of culture and the temperature at which it was incubated. The culture filtrate of 1/10- strength Tryptic Soy Broth medium, incubated for 48 hours at 30 -
A Bacterial Endophyte, Pseudomonas brassicacearum YC5480 Isolated from the Root of Artemisia sp. Producing Antifungal and Phytotoxic Compounds
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2008, 24권 4호 13 461-468 (8 pages)
An endophytic bacterial strain YC5480 producing antifungal and phytotoxic compounds simultaneously was isolated from the surface sterilized root of Artemisia sp. collected at Jinju area, Korea. The bacterial strain was identified as a species of Pseudomonas brassicacearum based on its 16S rRNA gene sequence analysis and physiological and biochemical characteristics. The seed germination and growth of monocot and dicot plants were inhibited by culture filtrate (1/10-strength Tryptic Soy Broth) of... -
Purification and Phytotoxicity of Apicidins Produced by the Fusarium semitectum KCTC16676
한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2008, 24권 4호 7 417-422 (6 pages)
Apicidin is a cyclic tetrapeptide produced by some Fusarium species and is known to inhibit Apicomplexan histone deacetylase. The goals of this study were to determine species identity of Fusarium isolate KCTC16676, an apicidin producer, to improve a method for apicidin extraction, and to test phytotoxicity of apicidin and its analogs. We compared sequences of the translation elongation factor 1-alpha (TEF) gene in KCTC16676 with those from isolates representing diverse Fusarium species, which... -

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... -

and Fourier-transform infrared spectroscopy; to determine the gel fraction, degree of swelling, gel strength, kinetics-of-swelling analyses and removal of hexavalent chromium (Cr(VI)) from the aqueous solution. X-ray diffraction results confirmed that EBI played a significantly important role in reducing GO to graphene. The adsorption equilibrium of Cr(VI) was reached within 80 min and the adsorption capacity was dramatically increased as the acidity of the initial solution was decreased from pH...
