The potential ecological impact of disinfection by-products (DBPs) present in chlorinated wastewater effluents is not well understood. In this study, the chlorinated effluent of traditional wastewater treatment plants (WWTPs) and advanced water reclamation plants (AWRPs) supplying highly-treated recycled water were analyzed for nitrosamines and(More)
The presence of bromide (Br(-)) and iodide (I(-)) in source waters leads to the formation of brominated and iodinated disinfection by-products (DBPs), which are often more toxic than their chlorinated analogues. The increasing scarcity of water resources in Australia is leading to use of impaired and alternative water supplies with high bromide and iodide(More)
Inoculation of wheat seedlings by the crown rot pathogen Fusarium pseudograminearum is commonly used to screen for resistance based on leaf sheath discolouration. While leaf sheath discolouration is effective for describing disease reactions, the degree to which the pathogen colonises the full range of seedling host tissues is an important aspect of the(More)
The effect of aeration combined with the delayed addition of selenite on the lag period of several strains of salmonellae and other enterobacteria is reported. A procedure has been developed involving shaking of the sample in a basal medium for 4 hr at 37 C, adding selenite and cystine, and continuing shaking for 20 hr. Confirmation by selective plating,(More)
Hexaploid/tetraploid and tetraploid/hexaploid wheat hybrids were established using the hexaploid (Triticum aestivum L.) bread wheat LRC2010-150 and the tetraploid durum wheat (T. turgidum spp. durum) WID802. Thirty F2 progeny from each cross were characterised using Diversity Arrays Technology (DArTseq™) markers to determine whether there are differences(More)
Disease severity of crown rot (Fusarium pseudograminearum) in winter cereal culms is typically assessed at harvest maturity by recording incidence of infection, whitehead production and discolouration of basal internodes. This study has investigated the relationship between the proportion of discolouration of individual internodes and the extent of host(More)
