The establishment and characterisation of a nitrifier population in a continuous-flow multi-stage model used to study microbial growth and interactions inherent in aquatic ecosystems

Abstract

The enrichment, isolation and establishment of a population of nitrifiers within a continuous-flow multi-stage model is described. The establishment and, subsequent, spatial separation of the components of a nitrifier population within the model appeared to be dependent on: specific growth rate/overall dilution rate, as dictated by the cumulative chamber volume, at various points along the model; and the interactions between the micro-organisms and the prevailing environmental conditions.
