Validity of Monod kinetics at different sludge ages – Peptone biodegradation under aerobic conditions

Pyrosequencing reveals the inhibitory impact of chronic exposure to erythromycin on activated sludge bacterial community structure

“…In fact, recent modeling efforts now include processes such as hydrolysis and storage as refinements in the mechanistic interpretation of substrate utilization; however, they still represent the microbial community sustained in the system by means of a single parameter-biomass [37,38]. Therefore, process kinetics in bioreactors used in environmental applications-and also elsewhere involving a complex, multicomponent microbial community-are numerically defined in terms of a set of kinetic coefficients reflecting the overall response/characteristics of the microbial culture.…”

“…Peptone mixture was selected mainly because it was prescribed as standard substrate for inhibition studies based on respirometry [34][35][36][37] and its COD composition includes a number of fractions with different characteristics similar to real wastewaters [34].…”

Effect of sludge age on population dynamics and acetate utilization kinetics under aerobic conditions

“…composition of the microbial communityhow it is changed under different conditions, and how this affects the observed process kinetics for organic substrate utilization. Even though many studies were reported on biomass characterization of activated sludge, objectives of these studies were diverse and therefore results were not conclusive (Orhon et al, 2009;Lemos et al, 2008).…”

Error propagation in open respirometric assays

“…Respirometric methods have been used to determine parameters of kinetic models that describe the aerobic biodegradation of wastewaters, single compounds, or mixtures of chemicals Orhon et al, 2009). These techniques were also employed to evaluate the biodegradable fraction of wastewaters (Lagarde et al, 2005), and to monitor the acclimation process of an activated sludge to a new environment (Carvalho et al, 2004;Aktas, 2012).…”
