Complete plastid genome (plastome) sequences and nuclear ribosomal DNA (nrDNA) regions have been proposed as candidates for the next generation of DNA barcodes for plant species discrimination. However, the efficacy of this approach still lacks comprehensive evaluation. We carried out a case study in the economically important but phylogenetically and taxonomically difficult genus Panax (Araliaceae)...
Background Robust phylogenies for species with giant genomes and closely related taxa can build evolutionary frameworks for investigating the origin and evolution of these genomic gigantisms. Paris japonica (Melanthiaceae) has the largest genome that has been confirmed in eukaryotes to date; however, its phylogenetic position remains unresolved. As a result, the evolutionary history of the genomic...
Electrocatalytic oxidation of indomethacin on a modified multiplewalled carbon nanotubes (MWCNTs) cathode in aqueous solution was studied in this paper. The experiments were carried out to explore the effects of initial concentration, electrolytic voltage, pH, concentration of electrolyte and electrolysis time on removal rate of indomethacin. The results of show that the removal rate reached 78% by...
Intermittent testing method used to study the operating characteristic of the two-phase anaerobic process dealing with the low concentration of wheat straw-containing wastewater. The wheat straw dosage within the acidogenic reactor and the change of pH, ammonia nitrogen, COD and VFA in the two-phase anaerobic reactor were investigated. The result indicated that two-phase anaerobic treatment was still...
Ionic liquids are receiving considerable attention because of their remarkable properties, such as extremely low vapor pressure. 1-Butyl-3-methylimidazolim tetrafluoroborate is one of the most commonly used ionic liquid. But it is toxic to aquatic organisms and is difficult to biodegradable. In this paper, some of the possible factors, which have effects on removal efficiency of 1-butyl-3-methylimidazolim...
