Daqu is a fermentation starter used in the production of Chinese liquors. A thermophilic bacterium, designated strain H-18(T), was isolated from a high-temperature Daqu sample collected from the manufacturing process of a sesame-flavoured liquor in Shandong province, China. It was investigated in a taxonomic study using a polyphasic approach. Strain H-18(T)(More)
Four Gram-stain positive bacterial strains, designated as 4R1T, 4R9, 4L13 and 4L18, isolated from seeds of hybrid maize (Zea mays L., Jingke 968), were investigated using a polyphasic taxonomic approach. The cells were found to be facultatively aerobic, motile, spore-forming and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences showed that(More)
A sensitive and selective method for separating fluoroquinolones (FQs) from bovine milk samples was successfully developed using montmorillonite magnetic molecularly imprinted polymers (MMMIPs) as adsorbents. MMMIPs were prepared using montmorillonite as carrier, fleroxacin (FLE) as template molecule, and Fe3O4 magnetite as magnetic component. MMMIPs(More)
The Enterobacteriaceae are a class of gram-negative facultative anaerobic rods, which can cause a variety of diseases, such as bacteremia, septic arthritis, endocarditis, osteomyelitis, lower respiratory tract infections, skin and soft-tissue infections, urinary tract infections, intra-abdominal infections and ophthalmic infections, in humans, poultry,(More)
Two yellow bacterial strains, designated NBD5(T) and NBD8, isolated from Noni (Morinda citrifolia L.) branch were investigated using a polyphasic taxonomic approach. Cells were Gram-stain-negative, aerobic, non-spore-forming, non-motile and short rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences suggested that the strains were members of a(More)
Thermoactinomyces daqus H-18 is a new species of Thermoactinomyces isolated from high-temperature Daqu used in the fermentation of Bandongjing sesame-flavor liquor. Its genome was sequenced and assembled (3.44 Mb). The coding sequences (CDSs) that correlated to high-temperature tolerance were annotated. The metabolic pathways for the compounds responsible(More)
Escherichia phage CICC 80001 was isolated from the bacteriophage contaminated medium of an Escherichia coli strain HY-05C (CICC 11022S) which could produce l-aspartic acid. The phage had a head diameter of 45–50 nm and a tail of about 10 nm. The one-step growth curve showed a latent period of 10 min and a rise period of about 20 min. The average burst size(More)
A novel molecularly imprinted electrochemical sensor (MIECS) was proposed to determine olaquindox (OLA) using gold nanoparticles in molecularly imprinted polymer (AuNPs@MIP) and carboxylated multi-walled carbon nanotubes (cMWCNTs). Glassy carbon electrode (GCE) was modified with cMWCNTs (cMWCNTs/GCE), and AuNPs/cMWCNT/GCE was obtained by electrodeposition(More)
A simple, fast, reproducible and efficient one-step fabrication method was successfully developed to prepare gold nanoparticle/carbon nanosheet (Au NP/CNS) hybrids by using sonoelectrochemistry. This method involved simultaneous generation of carbon nanosheets (CNSs) by oxidation of a graphite anode and generation of Au NPs by reduction of AuCl4(-) on the(More)
A Gram-stain-positive, facultatively anaerobic, thermophilic bacterium, designated ZQ18-1T, was isolated from a high temperature daqu sample collected from the sesame-flavour liquor-making process. Oval endospores were formed at the centre of cells with swollen sporangia. The isolate was able to grow at temperatures of 20-60 °C (optimum growth at 50 °C), at(More)
