A new approach to toxicity determination by respirometry
Environmental Technology, 2009Respirometry, as used in wastewater treatment, is the measurement and interpretation of the respiration rate of microorganisms in activated sludge. The respiration rate is the amount of the oxygen per unit of volume and time that is consumed by the microorganisms.

On Line Respirometry: A Powerful Tool for Activated Sludge Plant Operation and Design
Water Science and Technology, 1993 This paper will describe, with minimal reference to mathematically derived formulae, the importance and use of respirometry as a design and process operating tool. The authors will report on the latest findings of their team working in the United Kingdom.

Respirometry for Assessing the Biodegradation of Petroleum Hydrocarbons
Environmental Technology, 2005The respiration method using the Micro-Oxymax respirometer was applied to evaluate the bioremediation potential of hydrocarbon-contaminated soils in two biopiles at the oil refinery in Czechowice-Dziedzice, Poland. In biopiles 1 and 2, two different technologies, i.e., enhanced (engineered) bioremediation and monitored natural attenuation (MNA) were ...

Measurement of Futile Creatine Cycling Using Respirometry
2022Thermogenic adipose tissue plays a vital function in regulating whole-body energy expenditure and nutrient homeostasis due to its capacity to dissipate chemical energy as heat, in a process called non-shivering thermogenesis. A reduction of creatine levels in adipocytes impairs thermogenic capacity and promotes diet-induced obesityKazak et al, Cell 163,

Tuning the parameters for fast respirometry
Analytica Chimica Acta, 2002Abstract The aerobic bacterial respiration rate is an indicator of microbial growth and metabolism, essential for monitoring the oxidation process and organic load content of samples in a diverse field of application from influent streams in wastewater treatment facilities to industrial fermentations.

This chapter describes the theory and practical applications of coulometric respirometry. Coulometric respirometry is probably the most accurate method for measuring oxygen consumption rates. It is ideal for small animals and has the dual advantages of high sensitivity and the fact that the oxygen in the organism’s environment is not depleted, allowing

Errors in volumetric respirometry: Description of an improved microrespirometer
Analytical Biochemistry, 1971Abstract 1. 1. When the capabilities for simplicity of construction and operation of the capillary volumeter are carried to extremes, certain random and constant errors appear which render the instrument unstable and insensitive. Some implications of these errors for respiration data in the literature are discussed. 2. 2.

Flow-through Respirometry: The Equations
2008This chapter demystifies respirometry equations, showing how they can be derived using a simple mental trick: focusing the analysis on the principal gas that is neither consumed nor produced by animals. The effect of dilution of oxygen by carbon dioxide, the enrichment of carbon dioxide by the consumption of oxygen, and the effects of water vapor on ...
