Microbiological characteristics оf cambisols from Western Balkan Mountains (Bulgaria)

open access: yesПочвознание, агрохимия и екология, 2016
Changes in microbial population density and basal soil respiration of Cambisols from Western Balkan Mountains due to the influence of vegetation cover (grassland, pine forest and beech forest) were studied, and their relations with soil properties were ...

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

open access: yesDeep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Antibacterial Activity of Heteropolytungstates Against Proteus mirabilis

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
We investigated the in vitro antibacterial activity of several heteropolytungstates against P. mirabilis, a drug‐resistant pathogen. All tested polyanions inhibited bacterial growth, with the Preyssler–Pope–Jeannin polyanion P5W30 exhibiting the highest activity (MIC = 0.78 mg/mL).

Characteristics of Wetting-Induced Bacteriophage Blooms in Biological Soil Crust

open access: yesmBio, 2019
Biological soil crusts (biocrusts) are photosynthetic “hot spots” in deserts and cover ∼12% of the Earth’s terrestrial surface, and yet they face an uncertain future given expected shifts in rainfall events.

Air pollution exposure during training impairs performance in Thoroughbred racehorses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Ambient air pollution contributes substantially to human morbidity and mortality, and athletes are recognised as a particularly vulnerable group. However, little is known about the impact of air pollution on equine athletes. Objectives To explore the relationship between air pollution exposure during the pre‐competition training ...

Ammonia Oxidation by the Arctic Terrestrial Thaumarchaeote Candidatus Nitrosocosmicus arcticus Is Stimulated by Increasing Temperatures

open access: yesFrontiers in Microbiology, 2019
Climate change is causing arctic regions to warm disproportionally faster than those at lower latitudes, leading to alterations in carbon and nitrogen cycling, and potentially higher greenhouse gas emissions.

The distribution and diversity of actinomycetes in soil fractions [PDF]

open access: yes
The results presented were concerned with the survival of Streptomyces coelicolor A3(2) (pll673) inoculated into soil microcosms, which were destructively fractionated so that the total propagules and spore counts could be determined in each of the ...

Efficient Separation and Purification of Oligosaccharides: A Systematic Review on Principles and Applications of Membrane Separation Technology

open access: yesFood Bioengineering, EarlyView.
Membrane separation provides a green and scalable route for oligosaccharide purification. This review summarizes the complementary roles of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, with emphasis on membrane selection, optimization of operating conditions, fouling control, and integrated cascade design for improving purity,
