Multi-source DOM inputs dictate net extra carbon mineralization in eutrophic lakes via non-linear co-metabolism effects
Microbially mediated decomposition of dissolved organic matter (DOM) is a key process in the carbon cycle of inland lakes. Exogenous DOM inputs can alter the decomposition of resident lake-water DOM through co-metabolic effects (CE), yet how DOM source and addition level jointly regulate this process remains poorly understood, especially in eutrophic lakes. Here, we selected Lake Taihu, a…
