Fig. 1. Total respiration (a) and respiration of lignocellulosic carbon (b) with time (μg C mL-1wet sediment).
Data from CTRL (background mineralisation), 13C-CTRL (13C-lignocellulose) and dual substrate treatments 1D and 2D (13C-lignocellulose + unlabelled diatoms) are represented by diagonal crosses, circles, and open/filled triangles respectively. Values are mean ± SE (n = 3).
Fig. 2. Incorporation of lignocellulosic carbon into bacterial (a) and eukaryotic (b) biomass with time and treatment based on the 13C enrichment of PLFA biomarkers.
Data in (a) exactly overlap so that symbols for 13C-CTRL and 1D are hidden under the 2D filled triangles. Data represent the mean ± s.e.m. (n = 3).
