The relationship between substrate-induced respiration and swelling in Azotobacter vinelandii

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971
Abstract 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, 1996
Abstract 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.

Substrate-induced respiration as a measure of microbial biomass in vermicomposting studies

Bioresource Technology, 2010
Here 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.

Substrate induced respiration in soil amended with different amino acid isomers

Applied Soil Ecology, 1994
Abstract The substrate induced respiration (SIR) by the soil microbial community was determined using glucose, l -alanine, d -alanine, l -glutamine and d -glutamine as the substrate in order to compare the utilization of l - and d -isomers of alanine and glutamine by the microbial community in a podzolic soil.

Microbial community structure and function during abnormal curve development of substrate-induced respiration measurements

Chemosphere, 2009
Soil respiration measurements are an established method to test the abundance, activity and vitality of the soil microorganisms. However, abnormal progressions of soil respiration curves impede a clear interpretation of the data. The aim of this study was to investigate the changes in the microbial structure during the formation of phenomena like ...

Relationships between fungal and bacterial substrate-induced respiration, biomass and plant residue decomposition

Soil Biology and Biochemistry, 1991
Abstract Residues of six plant species were incubated in the field and analyzed for decomposition rates, fungal, bacterial and total substrate-induced respiration (SIR), total fungal and bacterial biomass and changes in residue composition during 161 days. Plant residues included crimson clover ( Trifolium incarnatum L.), hairy vetch ( Vicia villosa

Effects of warming, wetting and nitrogen addition on substrate-induced respiration and temperature sensitivity of heterotrophic respiration in a temperate forest soil

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.

Effects of substrate induced respiration on the stability of bottom ash in landfill cover environment

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2014
The municipal solid waste incineration bottom ash is being increasingly used to construct landfill covers in Sweden. In post-closure, owing to increased cover infiltration, the percolating water can add external organic matter to bottom ash. The addition and subsequent degradation of this external organic matter can affect metal mobility through ...

Effects of water amendment on basal and substrate-induced respiration rates of mineral soils

Biology and Fertility of Soils, 1989
We 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.

Substrate‐Induced Respiration of a Sandy Soil Treated with Different Types of Organic Waste

Communications in Soil Science and Plant Analysis, 2010
A sandy soil was amended with different types of sewage sludge (digested, dried, and composted) and pig slurry. The composted sludges displayed higher organic‐matter stability (39–45%) than only digested sludge (26–39%) or digested + dried sludge (23–32%). The microbial biomass of the dried sludge was undetectable.
