SPP 1315: Impact of pesticides and oxygen on microbial cellulose degradation in aerated agricultural soils: A microscaled analysis of processes and prokaryotic populations
Description:
Cellulose is one of the most abundant carbonaceous compounds in terrestrial ecosystems, and its mineralization in agricultural soils contributes significantly to the global CO2 budget. Pesticides may affect the activities (e.g. beta-glucosidase) of soil microbes; however, their potential effect on the degradation of cellulose has not been resolved. Likewise, although it is common knowledge that microbes in soil aggregates are exposed to dynamic oxygen concentrations, the importance of steep oxygen gradients over soil aggregate surfaces to the mineralization of cellulose is unclear. Indeed, despite the relatively large amount of information available on novel cellulose-utilizing microbes in aerated soils the in situ relevance of these isolates is unresolved.
