Notes.

^aCarbohydrate, protein, and lipid contents of algal detritus were determined before and after enrichment. Percentages are calculated based on the dry weight at T_f. Original algal detritus composition was as follows (%Carbohydrate: %Protein: %Lipid): Chara, 88:6.5:5.5; Chlorella, 86.7:13.3:0; Kelp, 67.9:14.1:18.

^bLipids in Chlorella biomass were BDL.

^cBased on dry weight remaining at the end of enrichment (DW_f), and the initial dry weight used for enrichment (DW₀) using the equation: % biomass loss = (DW₀ − DW_f)/DW₀ × 100. Initial dry weight for kelp was equivalent to the weight added to each enrichment bottle since it was in dry powder form. However, initial dry weight for Chara and Chlorella was determined by incubating an amount equivalent to the wet weight added to each enrichment bottle overnight at 40 °C then weighing its dry weight following moisture loss.
