Differences in the substrate spectrum of extracellular enzymes in shallow lakes of differing trophic status
Abstract Organic matter fluxes and food web interactions in lakes depend on the abilities of
heterotrophic microbial communities to access and degrade organic matter, a process that
begins with extracellular hydrolysis of high molecular weight substrates. In order to
