Microbial mineralization of cellulose in frozen soils
Abstract
High latitude soils can store around 40 % of the Earth’s soil carbon. Here, the authors add 13C-labeled cellulose to frozen mesocosms of boreal forest soils and find that cellulose biopolymers are hydrolysed under frozen conditions and therefore contribute to the slow degradation of soil organic matter.
