A circular economy offers solutions for global sustainability challenges through the transition from linear take-make-use-dispose to a better organisation of resources. However, realising has ran into various biophysical constraints. Circular implementation is shaped by Ellen MacArthur Foundation's butterfly diagram that depicts 'biological' and 'technical' flows as separate cycles, subsequently interpreted organic materials circulating in open loop systems via environment inorganic closed...
Soils in tropical and temperate locations are known to be a sink for the genetic potential of anthropogenic-driven acquired antibiotic resistance (AR). In contrast, accumulation AR is less probable most Polar soils, providing platform characterizing background establishing benchmark assessing spread. Here, high-throughput qPCR geochemistry were used quantify abundance diversity both genes (ARGs) selected mobile elements (MGEs) across eight soil clusters Kongsfjorden region Svalbard High...
Effective domestic wastewater treatment is among our primary defenses against the dissemination of infectious waterborne disease. However, reducing amount energy used in processes has become essential for future. One low-energy option anaerobic-aerobic sequence (AAS) bioreactors, which use an anaerobic pretreatment step (e.g., hybrid reactors) to reduce carbon levels, followed by some form aerobic treatment. Although AAS common warm climates, it not known how its compares other options...
The cost of materials is one the biggest barriers for wastewater driven microbial fuel cells (MFCs). Many studies use expensive with idealistic wastes. Realistically choice an ion selective membrane or nonspecific separators must be made in context and performance available. Fourteen membranes were characterized durability, oxygen diffusion ionic resistance to enable informed selection reactor tests. Subsequently MFCs operated a efficient design using Nafion, ethylene tetrafluoroethylene...
A large portion of the World's terrestrial organic carbon is stored in Arctic permafrost soils. However, due to warming and increased situ microbial mineralisation released carbon, greenhouse gas releases from soils are increasing, including methane (CH4(g)). To identify environmental controls on such releases, we characterised soil geochemistry community conditions 13 near-surface collected across Kongsfjorden, Svalbard. Statistically significant correlations were found between proxies for...
Thousands of Neolithic and Bronze Age open-air rock art panels exist across the countryside in northern England. However, desecration, pollution, other factors are threatening survival these iconic stone monuments. Evidence suggest that rates panel deterioration may be increasing, although it is not clear whether this due to local or wider environmental influences accelerated by change. To examine question, 18 with varied motifs were studied at two major locations Lordenshaw Weetwood Moor...
Abstract. Controls on in situ methanotroph activity are not well understood. One potentially important parameter is copper (Cu) because it the metal-centre of particulate methane monooxygenase (pMMO), most active enzyme for oxidizing to methanol. Further, Cu-to-cell ratios influence relative expression pMMO versus alternate soluble MMO (sMMO) some species. However, studies only have assessed readily forms Cu (e.g. CuCl2) and there a dearth Cu-related data sources more common environment....
Many factors affect the performance of microbial fuel cells (MFCs). Considerable attention has been given to impact cell configuration and materials on MFC performance. Much less work done anode microbiota, particularly in context using complex substrates as fuel. One strategy improve such wastewater, is pre-enrich with known, efficient electrogens, Geobacter spp. The implication this that electrogens are limiting factor MFCs fed organisms feeding through hydrolysis fermentation not...
Summary As we transition from fossil fuel reliance to a new energy future, innovative microbial biotechnologies may offer routes maximize recovery conventional and unconventional assets; as well contributing reduced emission pathways technologies for carbon capture utilization. Here discuss the role of microbiology in petroleum relation addressing UN Sustainable Development Goal 12 (ensure sustainable consumption production patterns), with focus on microbially‐mediated unconventionals (heavy...

Weak and unstable soils can limit the building of new infrastructure. Current soil strengthening techniques such as chemical grouting have detrimental effects on environment from greenhouse gas production, pH modification groundwater contamination. Microbial-induced calcium carbonate precipitation (MICCP) is a technique that utilises ability bacteria to precipitate carbonate, which be used for variety applications including binding adjacent particles filling pore spaces increase their...
