Pine-Suillus Symbiosis Study
Ectomycorrhizal fungi (EMF) are emerging as a model system for understanding microbial community dynamics and the linkages between microbial communities and ecosystem function. EMF provide their plant hosts with nutrients such as nitrogen, phosphorous, and water, in exchange for fixed carbon. Trade between the two partners constitutes a significant ecosystem flux in resources between plant… [Read More]
A Permafrost Thaw Chronosequence in Sweden
Permafrost is a key globally important ecosystem, storing massive amounts of carbon across a large area. Permafrost-associated soils cover nearly a quarter of the terrestrial land surface, contain more than a third of the world’s soil carbon, and are thawing due to climate change. The fate of the stored carbon is a key unknown in… [Read More]
Model for Methane and Microbial Metabolism
Methane hydrates are pockets of methane trapped inside a solid structure of water and are often found in ocean floor sediments. Marine continental margin sediments that bear these methane hydrates are estimated to contain up to 2,000 billion metric tons of methane. Anaerobic methanotrophic archaea and sulfate-reducing bacteria (ANME-SRB consortia) account for the oxidation of… [Read More]
Testing synthesized genes in A. niger
Aspergillus niger is used in industry for the production of enzymes for biomass degradation and other applications. It is also a useful host for expressing glycoside hydrolase (GH) genes from bacteria that have valuable properties. However, researchers do not fully understand the factors that provide high titer production of heterologous enzymes in fungal hosts. The… [Read More]
