Liquid chromatography/tandem mass spectrometry (LC-MS/MS) with electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI) was used to measure the concentrations of 14 pharmaceuticals, 6 hormones, 2 antibiotics, 3 personal care products (PCPs), and 1 flame retardant in surface waters and wastewater treatment plant effluents in South(More)
The inhibition of nitrification by phenol and copper mixtures was studied to investigate the differences between individual and mixture inhibition as the change of phenol and copper speciation due to their reactions. This study showed a decrease in the ammonium removal rate (k, first-order rate coefficient), indicating an increase in the relative %(More)
A novel heterotrophic, yellow pigmented, aerobic, Gram-negative, nonmotile, oxidase- and catalase-positive bacterium KMM 3938T was isolated from sea water collected in the Sea of Japan, Russia. The strain grew at mesophilic temperature range, and required the presence of NaCl for growth. 16S rRNA gene sequence analysis revealed that strain KMM 3938T is a(More)
A taxonomic study was carried out on a bacterial strain, designated KM-45T, isolated from forest soil collected near Daejeon, South Korea. Comparative 16S rRNA gene sequence analysis indicated a clear affiliation of this bacterium to the 'Betaproteobacteria' and that it was related most closely to Chitinibacter tainanensis BCRC 17254T, Formivibrio citricus(More)
A bacterial strain, designated KMM 6049T, was isolated from the sea urchin Strongylocentrotus intermedius inhabiting the Sea of Japan. The bacterium studied was strictly aerobic, heterotrophic, yellow-pigmented, non-motile, Gram-negative and oxidase-, catalase-, beta-galactosidase- and alkaline phosphatase-positive. 16S rRNA gene sequence analysis indicated(More)
Streptomyces coelicolor produces an extracellular protease inhibitor protein, STI (Streptomyces trypsin inhibitor). We show that post-growth elimination of STI is needed for colonies to develop aerial mycelium efficiently. Inactivation of STI, and thus the normal progression of colony development, at least partly involves an extracellular protease specified(More)
Viral safety is an important prerequisite for clinical preparations of all biopharmaceuticals derived from plasma, cell lines, or tissues of human or animal origin. To ensure the safety, implementation of multiple viral clearance (inactivation and/or removal) steps has been highly recommended for manufacturing of biopharmaceuticals. Of the possible viral(More)
A marine, heterotrophic, Gram-negative, aerobic, yellow-pigmented, bacterium that was motile by gliding, isolated from the green alga Acrosiphonia sonderi, was studied by polyphasic taxonomic methods. 16S rRNA gene sequence analysis indicated that strain KMM 6031T formed a distinct lineage within the family Flavobacteriaceae. On the basis of phenotypic,(More)
A novel marine bacterium, strain KMM 6050T, was isolated from the sea urchin Strongylocentrotus intermedius, which inhabits the Sea of Japan. The strain studied was strictly aerobic, heterotrophic, yellow-orange-pigmented, motile by gliding, Gram-negative and oxidase-, catalase-, beta-galactosidase- and alkaline phosphatase-positive. The results of 16S rRNA(More)
A novel xylan-degrading bacterium, S3-E(T), was isolated from the biofilm of a membrane bioreactor. The cells of this strain were Gram-positive, non-motile, non-spore-forming rods, produced primary branches and formed yellow colonies on nutrient agar. The strain had chemotaxonomic markers that were consistent with classification in the genus Microbacterium,(More)
