Journal ArticleDOI
Biology of Acinetobacter baumannii: Pathogenesis, Antibiotic Resistance Mechanisms, and Prospective Treatment Options.
Chang-Ro Lee,Jung Hun Lee,Moonhee Park,Kwang Seung Park,Il Kwon Bae,Young Bae Kim,Chang-Jun Cha,Byeong Chul Jeong,Sang Hee Lee +8 more
TL;DR: Current studies on the virulence factors that contribute to A. baumannii pathogenesis are summarized and Mechanisms of antibiotic resistance of this organism, including acquirement of β-lactamases, up-regulation of multidrug efflux pumps, modification of aminoglycosides, permeability defects, and alteration of target sites are discussed.
Journal ArticleDOI
Biotransformation of malachite green by the fungus Cunninghamella elegans.
TL;DR: The filamentous fungus Cunninghamella elegans ATCC 36112 metabolized the triphenylmethane dye malachite green with a first-order rate constant of 0.029 μmol h−1 (mg of cells)−1 to convert to N-demethylated and N-oxidized metabolites, including primary and secondary arylamines.
Journal ArticleDOI
Antimicrobial Resistance of Hypervirulent Klebsiella pneumoniae: Epidemiology, Hypervirulence-Associated Determinants, and Resistance Mechanisms.
Chang-Ro Lee,Jung Hun Lee,Kwang Seung Park,Jeong Ho Jeon,Young Bae Kim,Chang-Jun Cha,Byeong Chul Jeong,Sang Hee Lee +7 more
TL;DR: The authors in this paper provided a summary and discussion focused on epidemiology, hypervirulence-associated factors, and antibiotic resistance mechanisms of such hypervirulent K. pneumoniae isolates.
Journal ArticleDOI
Bacterial community analysis during fermentation of ten representative kinds of kimchi with barcoded pyrosequencing.
TL;DR: It was found that bacterial communities differed between starter-inoculated and non- inoculated kimchi at the early stages of fermentation, but overall there were no significant differences in the late phases.
Journal ArticleDOI
A master regulator σB governs osmotic and oxidative response as well as differentiation via a network of sigma factors in Streptomyces coelicolor
Eunjin Lee,Nitsara Karoonuthaisiri,Hyo Sub Kim,Joo-Hong Park,Chang-Jun Cha,Camilla M. Kao,Jung-Hye Roe +6 more
TL;DR: The results support a hypothesis that σB serves as a master regulator that triggers other related sigma factors in a cascade, and thus regulates differentiation and osmotic and oxidative response in S. coelicolor.
