In this study three dual limitation models (multiplicative, minimum, and Bertolazzi) were compared based on experiments using nitrite-oxidizing bacteria (limited by dissolved oxygen and nitrite) and ANaerobic AMMonia-OXidizing bacteria or Aanammox (limited by ammonium and nitrite) within mixed liquor from deammonification pilots.
The ability to tailor microalgal N P uptake ratio and target an optimal energy storage metabolism with traditional engineering process controls (such as SRT) may enable advanced nutrient recovery facilities to target continuous and reliable dual limitation of nitrogen and phosphorus.
As a result the dual limitation range shifts and slightly broadens, as described in Fig. 3.
According to Poblete-Castro et al. (2012) the same system was activated both under nitrogen limitation and under carbon nitrogen dual limitation.
In their work glnK showed a large change in both mRNA abundance and protein level when P. putida was subjected to dual limitation of nitrogen and carbon.
For example, at a C/N ratio of 2 molC/molN with nitrate-N, the system will result in a steady state in the dual limitation phase with coexistence of both processes, whereas at this ratio of 2 molC/molN for nitrite-N, in the steady state only nitrite will be limiting and DNRA dominates.
(2) dual pay limitations applicable to aggregate gross compensation of employees receiving single per annum rates of compensation.
L. 90 57 designated existing dual pay limitation provisions relating to basic compensation as par.
The dynamics of the substrate and oxygen consumption were measured during the batch experiment, and two mathematical models are developed to predict their transient responses using a Monod kinetic with dual substrate limitation.
Haemostasis is activated during sepsis and septic shock, leading to thrombin and fibrin generation with dual effects: limitation of pathogen diffusion and invasion; and fibrin deposition in vessels, resulting in thrombotic microangiopathy or disseminated intravascular coagulopathy.
The model is further extended to include dual substrate growth limitations, and the relative growth limiting characteristics of two substrates are evaluated.
