Development of an NDIR CO2 Sensor-Based System for Assessing Soil Toxicity Using Substrate-Induced Respiration [PDF]

open access: yesSensors, 2015
The eco-toxicological indicators used to evaluate soil quality complement the physico-chemical criteria employed in contaminated site remediation, but their cost, time, sophisticated analytical methods and in-situ inapplicability pose a major challenge ...

Positive relationship between substrate-induced respiration rate and translationally active bacterial counts in soil [PDF]

open access: yesmSystems
Soil microorganisms perform biogeochemical processes fundamental to soil functions. Bulk respiration, or microbial metabolic emission of CO2, is the classic indicator of soil biological activity.

Development of Substrate Induced Respiration (SIR) Method Combined with Selective Inhibition for Estimating Fungal andBacterial Biomass in Humic Andosols

open access: yesPlant Production Science, 2004
A substrate-induced respiration (SIR) method combined with selective inhibition for estimating the fungal and bacterial biomass of volcanic ash of Kanto Loam type (Humic Andosols) was developed.

Exploring the Influence of Diverse Viticultural Systems on Soil Health Metrics in the Northern Black Sea Region

open access: yesSoil Systems, 2023
The present study investigates the functionalecological status of typical light clay soils in vineyards in the southern region of Crimea, using both traditional (including fallow soils) and organic land-use systems.

Impact of Olive Saplings and Organic Amendments on Soil Microbial Communities and Effects of Mineral Fertilization

open access: yesFrontiers in Microbiology, 2021
Plant communities and fertilization may have an impact on soil microbiome. Most commercial olive trees are minerally fertilized, while this practice is being replaced by the use of organic amendments.

Application of Degradable Carbon and Nitrogen Moderates Carbon Sequestration Potential of Biochar in Arable Soils

open access: yesEkológia (Bratislava), 2021
Biochar can affect CO2 emission and C sequestration from soils, but little is known about the effects of its re-application and interaction with easily accessible substrates.

Comparison of the Responses of Soil Enzymes, Microbial Respiration and Plant Growth Characteristics under the Application of Agricultural and Food Waste-Derived Biochars

open access: yesAgronomy, 2022
The conversion of bio-wastes to useful products such as biochar provide a suitable option not only to minimize the mass of wastes, but also to use the biochar as soil amendment.

Decreased carbon limitation of litter respiration in a mortality-affected piñon–juniper woodland [PDF]

open access: yesBiogeosciences, 2013
Microbial respiration depends on microclimatic variables and carbon (C) substrate availability, all of which are altered when ecosystems experience major disturbance. Widespread tree mortality, currently affecting piñon–juniper ecosystems in southwestern

Risk Assessment of Psychotropic Drugs on Mitochondrial Function Using In Vitro Assays

open access: yesBiomedicines, 2023
Mitochondria are potential targets responsible for some drug- and xenobiotic-induced organ toxicities. However, molecular mechanisms of drug-induced mitochondrial toxicities are mostly unknown.

The Calorigenic Nature of Hepatic Ketogenesis: An Explanation for the Stimulation of Respiration Induced by Fatty Acid Substrates [PDF]

open access: yesEuropean Journal of Biochemistry, 1983
The rates of O2 consumption during fatty acid oxidation to acetyl‐CoA and to CO2 were determined for isolated liver cells from starved rats on the basis of measured rates of respiration and ketogenesis. About 60% of the endogenous O2 uptake was associated with acetyl‐CoA formation.
