An evaluation of the substrate-induced respiration method
Soil Biology and Biochemistry, 1999Abstract Two ways of measuring substrate-induced respiration (SIR) following addition of glucose to soil, viz. solid glucose or glucose in solution, were tested on 13 soils sampled from arable, grassland and woodland sites ranging from pH 3.2 to 7.5. Generally similar patterns of CO2 evolution were found between soils following addition of glucose as

Substrate-induced respiration as a measure of microbial biomass in vermicomposting studies
Bioresource Technology, 2010Here it is evaluated the relationship between substrate-induced respiration (SIR) and microbial biomass C (C(mic), estimated by chloroform fumigation-extraction) in order to establish SIR as a quick technique to determine microbial biomass in vermicomposting processes.

Effects of water amendment on basal and substrate-induced respiration rates of mineral soils
Biology and Fertility of Soils, 1989We studied the effects of amending soils with different volumes of water or glucose solution on respiration rates measured as CO2 evolution. Basal respiration was not significantly affected by the volume of water amendment, but substrate-induced respiration in static soil solutions was significantly reduced by increasing water contents.

Translationally active soil microorganisms during substrate-induced respiration
2023ABSTRACT Soil microorganisms carry out many processes that are fundamental to soil functions. Among the millions of microbial cells present in a gram of soil, however, less than 2% are commonly estimated to be active at any point in time.

Pedosphere, 2021
Abstract Soil heterotrophic respiration and its temperature sensitivity are affected by various climatic and environmental factors. However, little is known about the combined effects of concurrent climatic and environmental changes, such as climatic warming, changing precipitation regimes, and increasing nitrogen (N) deposition.

The relationship between substrate-induced respiration and swelling in Azotobacter vinelandii
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971Abstract 1. 1. When oxidizable substrates are added to a starved suspension of Azotobacter vinelandii osmotically shrunken in 0.2 M KCl, a decrease in absorbance is observed which results from a change in light scattering as the cells increase in volume. 2. 2.

Measuring bacterial and fungal substrate-induced respiration in dry soils
Soil Biology and Biochemistry, 1996Abstract The substrate-induced respiration inhibition (SIRIN) method of Anderson and Domsch for partitioning bacterial and fungal contributions to soil respiration was modified for application to dry soils. This new method also provided a comparative basis when measuring SIRIN in soils of different moisture contents.
