Ecophysiology of the filamentous Alphaproteobacterium Meganema perideroedes in activated sludge.
A comprehensive study of the ecophysiology of the filamentous Meganema perideroedes affiliated to the Alphaproteobacteria, possessing a "Nostocoida limicola Type II" filamentous morphology was conducted. This morphotype often causes serious bulking problems in activated sludge wastewater treatment plants, and hardly anything is known about its physiology. The study was carried out by applying a...
متن کاملDenitrification, activity of bacterial floes, and growth of a filamentous bacterium in relation with the bulking of activated sludge
Floe formation by cells of Zoogloea ramigera, strain I-16-M, was observed after resuspending pre-cultivated cells in fresh medium. It was considerably stimulated by the additional supply of NaCl or Na2HP04/NaH2P04. Stimulated floe formation occurred also at an increased C/N ratio of the medium in which the pre-cultivated cells were resuspended. The growth phase of the cells had no effect on flo...
متن کاملA Comparative Study of the Efficiency of Granular Activated Sludge and Common Activated Sludge in the Removal of Chromium (VI) from Synthetic Solutions
Introduction: Aerobic granules as a novel type of bio-sorbent have an excellent settling ability and high-porosity structure. This study investigated the feasibility of aerobic granules for chromium (VI) removal from synthetic aqueous solution and compare it with conventional activated sludge. Method: In this research the effect of some important parameters including pH (5, 7, and 9), initial c...
متن کاملIsolates of 'Candidatus Nostocoida limicola' Blackall et al. 2000 should be described as three novel species of the genus Tetrasphaera, as Tetrasphaera jenkinsii sp. nov., Tetrasphaera vanveenii sp. nov. and Tetrasphaera veronensis sp. nov.
Despite differences in their morphologies, comparative analyses of 16S rRNA gene sequences revealed high levels of similarity (>94 %) between strains of the filamentous bacterium 'Candidatus Nostocoida limicola' and the cocci Tetrasphaera australiensis and Tetrasphaera japonica and the rod Tetrasphaera elongata, all isolated from activated sludge. These sequence data and their chemotaxonomic ch...
متن کاملFilamentous organism bulking in nutrient removal activated sludge systems
A model is outlined for the major biochemical respiratory mechanisms of a conceptualised heterotrophic facultative organism (representing the heterotrophic facultative mass of activated sludge) subjected to four different sets of conditions: steady-state aerobic, steady-state anoxic, steady-state aerobic changed to anoxic, and steady-state anoxic/anaerobic changed to aerobic. Proposals and impl...
