Genomic investigation ones organizations has shown they own a high potential to build such minerals than almost every other teams within this bacteria and you can fungus (Karlsson and you can Stenlid, 2008; Trivedi et al
Different microbial groups explained the abundance of genes encoding different enzymes (Figures 2 and 3a2–d2). , 2013; Zhao et al., 2013). The production of NAG and XYL was significantly linked to ?-Proteobacteria, Actinobacteria and Acidobacteria in bacteria and Eurotiomycetes (subphylum Pezizomycotina) and Leotiomycetes (very closely related to subphylum Pezizomycotina) in fungi (Figures 3a2 and c2). , 2013; Zhao et al., 2013). SEM showed that bacterial phyla Acidobacteria, Deltaproteobacteria and Actinobacteria are important predictors of activity of enzymes CB, XYL and NAG. These groups are classified as oligotrophs and thrive on moderately labile and recalcitrant forms on C (Fierer et al., 2007; Trivedi et al., 2013). We observed a small but significant (P<0.05) direct control of microbial structure on AG and CB activity. This is not surprising as AG and CB are involved in degradation of labile forms of C and the gene(s) encoding the production of AG and CB are present in a number of soil microbial groups (Trivedi et al., 2013; Zhao et al., 2013). The activity of all four studied enzymes was directly and significantly regulated by the abundance of genes encoding the respective enzymes (Figure 3). These results suggest that microbial community structure influences enzymatic activities through the relative abundance of functional genes. Future studies should expand to include a wide array of possible enzymes involved in C dynamics. This is now possible given the rapid advancement in sequencing and probe-based technologies over recent years.
The deficiency of direct evidence one to surface microorganisms regulate the enzymatic factors might have been the major bottleneck into the adding its structural and you can useful structure to possess forecasts. Has just, Wieder et al. (2015) enjoys provided bacterial functional designs one display copiotrophic and oligotrophic development steps during the a process-founded design to help you assume soil C return. Read more
