Short summary
Microbial production is a key parameter in estimation of organic matter cycling in environmental systems, and fungi play a major role as decomposers. In order to improve investigation of fungal production and turnover times in environmental studies, we determined the isotopic signals encoded into lipid biomarkers of fungal pure cultures growing on various carbon substrates in media with isotopically labeled water and bicarbonate.
