Mass balance of dry matter and organic matter and structural components (carbohydrates, nitrogen, lignin and ash) in the compost during composting and mycelium growth.

a Organic matter = Total dry matter–ash.b Recovery = Calculated as sum(carbohydrates+protein+total lignin +ash)/total dry matter*100.c Nitrogen to protein conversion factor 6.25.d Calculated as difference = total nitrogen-water insoluble nitrogen.e Corrected for ash.n.s. not specified. +/- STDEV between analytical duplicates.BM: basic mixture; PI: compost after Phase I; PII: compost after Phase II; PIII–16: compost after 16 days of mycelium growth for batch A.
