Why are micro - and micronutrients necessary?
18/05/2015
Macronutrients (C, H, N, O, S, P)
Cellstructure
for bacteriagrowth
Micronutrients (Se, Cu, Ni, B, Mo,
Mn, Zn)
Produce metabolic enzymes =

Results: Biogas Optimization
Addition of nutrients
Measurement of yield increase
Expected result:
20% - 40 % more biogasCost analysis
