...Bahareh Sorouri; Steven D. Allison It is critical to understand the consequences of environmental change for the microbial regulation of carbon and nutrient cycling. Specifically, understanding microbial community traits, such as extracellular enzyme activity, can help inform nutrient cycling...

...Jane Martinez; Jennie McLaren; Craig E. Tweedie; Anthony Darrouzet-Nardi Microbial processes, including extracellular enzyme (exoenzyme) production, are a major driver of decomposition and a current topic of interest in Arctic soils due to the effects of climate warming. While enzyme activity...

... polysaccharides — arabinogalactan, chondroitin sulfate, fucoidan, laminarin, pullulan, and xylan (all Sigma or Fluka; Table 1 ) — were labeled with fluoresceinamine and used as substrate for extracellular enzymes as described in Arnosti ( 1996 , 2003 ). In brief, single substrates were added to pre-autoclaved...
