TL;DR: It is suggested that the SBR could be used for the enrichment and quantitative study of a large number of slowly growing microorganisms that are currently out of reach for microbiological research.

TL;DR: In this paper, a new biological process for ammonia removal from flows containing hundreds to thousands milligrams NH + 4 per litre has been developed at the Delft University of Technology.

TL;DR: In this paper, a review of the microbiological and biochemical aspects of the enhanced biological phosphate removal (EBPR) process is presented, including microorganisms responsible for EBPR, isolation of polyphosphate accumulating organisms (PAOs), microbial diversity of the EBPR sludge, biochemical metabolisms of PAOs, energy budget in PAOs metabolism, denitrification by PAO, glycogen accumulating non-poly-P organisms (GAOs), etc.

TL;DR: It is shown that granule formation in aerobic reactors is feasible and can be exploited to increase the volumetric conversion capacity of such reactors.

TL;DR: On the basis of physiological as well as genetic properties, strains from the CEN.PK family were selected as a platform for cell-factory research on the stoichiometry and kinetics of growth and product formation.
