    Abstract

    Glucose and pH microprofiles in UASB aggregates were interpreted with respect to the population distribution of fermentative and methanogenic bacteria. In order to map the activity distribution of these bacteria, microprofiles were measured with different substrates (glucose, propionate and acetate) and at varying buffer capacities of the medium. The measurements were compared to calcd. microprofiles, in which the spatial location of the activities was varied. The results suggested an inhomogeneous activity distribution in the aggregates investigated: fermentative were located dominantly at the outer 200-300 mm whereas methanogens were homogeneously distributed over the aggregate.
