2008 journal article
Clarifying the roles of kinetics and diffusion in activated sludge filamentous bulking
BIOTECHNOLOGY AND BIOENGINEERING, 101(2), 327–336.
Contributors: n & F. Reyes n
author keywords: activated sludge; filamentous bulking; diffusion limitation; kinetic selection; floc size
MeSH headings : Biomass; Bioreactors; Diffusion; Flocculation; Kinetics; Models, Biological; Sewage / chemistry; Sewage / microbiology; Waste Disposal, Fluid / methods; Water Microbiology
TL;DR:
A model integrating the two factors was developed to simulate the substrate concentrations at different depths and floc sizes under intermittently feeding conditions, and modeling results confirmed that substrate diffusion limitation occurs inside the flocs at a certain range of activated sludge floc size sizes over the operation cycle, and provided additional support for the proposed framework.

2005 journal article
Integrating decay, storage, kinetic selection, and filamentous backbone factors in a bacterial competition model
WATER ENVIRONMENT RESEARCH, 77(3), 287–296.
Contributors: C. In n & F. De Los Reyes III
author keywords: bulking; kinetic selection; filamentous backbone; decay rate; storage; modeling
MeSH headings : Bacteria / growth & development; Bioreactors; Flocculation; Kinetics; Models, Theoretical; Monte Carlo Method
TL;DR:
Modeling filamentous bulking in activated sludge systems showed coexistence of the two organism types, and sensitivity analysis showed that the kinetic parameters, storage rate constants, and backbone coefficient had the greatest effect on the simulation results.

2005 journal article
Substrate uptake tests and quantitative FISH show differences in kinetic growth of bulking and non-bulking activated sludge
BIOTECHNOLOGY AND BIOENGINEERING, 92(6), 729–739.
Contributors: n & F. Los Reyes n
author keywords: growth rate; yield; maintenance coefficient; substrate uptake; metabolic modeling; quantitative FISH
MeSH headings : Bacteria / growth & development; Bacteria / metabolism; Biomass; Bioreactors; Gammaproteobacteria / growth & development; In Situ Hybridization, Fluorescence / methods; Models, Biological; Sewage / microbiology; Thiotrichaceae / growth & development; Thiotrichaceae / metabolism; Water Microbiology
TL;DR:
Substrate uptake tests combined with metabolic modeling showed that filamentous bulking sludge had lower growth rates and maintenance coefficients than non-bulkingSludge, providing support for growth kinetic differences in explaining the competitive strategy of filamentous bacteria.
