A microrespirometric method for the determination of stoichiometric and kinetic parameters of heterotrophic and autotrophic cultures

Respirometric assessment of bacterial kinetics in algae-bacteria and activated sludge processes

“…Half-saturation constants found in this study for AS were very close to previous studies (Orhon, 2015), though a wide range of values is available in the literature, reaching up to one order of magnitude more than those found in this work, i.e. up to 20-45 mg COD⋅L − 1 , depending on process characteristics (Esquivel-Rios et al, 2014). Regarding AB, as no experimental determination of the half-saturation values is available in the literature for HB, mathematical models describing the growth of AB consortia generally assume a value of 20 mg COD⋅L − 1 from the ASMs (Sánchez-zurano et al, 2021;Solimeno et al, 2019), or more similar values to those experimentally found in this study (4 mg COD⋅L − 1 ), as reported by Casagli et al (2021b).…”

Kinetic and microbiological characterization of aerobic granules performing partial nitritation of a low-strength wastewater at 10 °C

“…Thus µ max and K S,TAN resulted in 0.63±0.05 d -1 and 2.1±0.7 mg N L -1 , respectively. Different values of maximum growth rate have been reported up to now, being most of them determined at high temperatures (20-30 ºC)(Blackburne et al, 2007;Esquivel- Rios et al, 2014;Vadivelu et al, 2006). However, large discrepancies were found between different studies.…”

Respirometric evaluation of S0/X0 ratio effect on the kinetic and stoechiometric parameters of activated sludge

“…The profile of oxygen uptake rate, OUR, can provided much information about the treatment process and biomass viability [43][44][45][46] . Their determination is detailed in several studies; it requires the determination of the volumetric oxygen transfer coefficient K L a in the solution which is necessary for the interpretation of respirometric data [47] . In this case, the oxygen mass conservation is defined by (equation 1).…”
