The presence of natural estrogens, a class of endocrine disrupting compounds, in water has caused increasing concerns over their adverse impacts on the health of aquatic eco-systems and human beings. In this study, adsorption characteristics of two natural estrogens, 17β-estradiol (E2) and estrone (E1), on granular activated carbon (GAC) were investigated in isotherm tests and in a GAC column. The GAC column was then converted to a biologically active carbon (BAC) column and the removal efficiency of E2 and its primary biodegradation intermediate E1 were monitored. During BAC operation, the impacts of various reactor operation parameters, such as the carbon …

This is the first report of sequence-specific microsatellite markers (simple sequence repeats [SSRs]) of fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), an economically important pest of crops on the Americas.Weisolated 192 microsatellite markers by using pyrosequencing and screened 15 individuals from eight isofamilies collected from three geographical areas: Puerto Rico (PR), Texas (TX), and Mississippi (MS). Isofamilies resistant to Cry toxins from Bacillus thuringiensis (Berliner) (Bacillales: Bacillaceae) also were included. Cluster analysis was performed to determine the potential use of these SSRs in discriminating populations, and colonies were grouped with a reliability of 100% estimated by bootstrap. In this …
