The effects of metals (cadmium, zinc, copper and nickel in a mixture) on biosorption and biodegradation of five mixed polycyclic aromatic hydrocarbons (PAHs), namely fluorene (FLU), phenanthrene (PHE), fluoranthrene (FLA), pyrene (PYR) and benzo[a]pyrene (BAP), by Selenastrum capricornutum were investigated. Exposure to metals significantly influenced the(More)
Pyruvate kinase (PK) catalyzes the final step of glycolysis. There are few reports on the role of PK in rice. Here, we identified a novel rice dwarf mutant, designated as ospk1, showing dwarfism, panicle enclosure, reduced seed set, and outgrowth of axillary buds from culm nodes. Sequence analyses of 5′-RACE indicated that a single T-DNA was inserted in the(More)
A new surface imprinting technique was reported to synthesize multi-walled carbon nanotubes-molecularly imprinted polymers (MWNTs-MIPs) using erythromycin as the template, acryloyl-β-cyclodextrin (acryloyl-β-CD) and methacrylic acid (MAA) as the binary functional monomers. The MWNTs-MIPs were characterized by transmission electron microscopy (TEM), scanning(More)
Shigella and Salmonella are frequently isolated from various food samples and can cause human gastroenteritis. Here, a novel multiple endonuclease restriction real-time loop-mediated isothermal amplification technology (MERT-LAMP) were successfully established and validated for simultaneous detection of Shigella strains and Salmonella strains in only a(More)
Here, a novel model of loop-mediated isothermal amplification (LAMP), termed multiple inner primers-LAMP (MIP-LAMP), was devised and successfully applied to detect Listeria monocytogenes. A set of 10 specific MIP-LAMP primers, which recognized 14 different regions of target gene, was designed to target a sequence in the hlyA gene. The MIP-LAMP assay(More)
We have devised a novel isothermal amplification technology, termed endonuclease restriction-mediated real-time multiple cross displacement amplification (ET-MCDA), which facilitated multiplex, rapid, specific and sensitive detection of nucleic-acid sequences at a constant temperature. The ET-MCDA integrated multiple cross displacement amplification(More)
The article reported a novel methodology for real-time PCR analysis of nucleic acids, termed endonuclease restriction-mediated real-time polymerase chain reaction (ET-PCR). Just like PCR, ET-PCR only required one pair of primers. A short sequence, which was recognized by restriction enzyme BstUI, was attached to the 5' end of the forward (F) or reverse (R)(More)
A sample pretreatment method for the determination of 18 chlorophenols (CPs) in aqueous samples by derivatization liquid-phase microextraction (LPME) was investigated using gas chromatography-mass spectrometry. Derivatization reagent was spiked into the extraction solvent to combine derivatization and extraction into one step. High sensitivity of 18 CPs(More)
In this study, a surface-coated wooden-tip electrospray ionization mass spectrometry (SCWT-ESI-MS) method was developed for rapid and sensitive analysis of trace fluoroquinolone and macrolide antibiotics in water. First, a SCWT solid-phase microextration (SPME) probe was prepared, via silanization and sulfonation for modification of a layer of adsorbent(More)
Anthracnose caused by Colletotrichum gloeosporioides is one of the most destructive fungal diseases of many plants, including stylo (Stylosanthes spp.), which is an important tropical forage legume. Although C. gloeosporioides-caused anthracnose is the major constraint limiting the growth and yield of stylo, little information is available regarding the(More)
