TRACE ELEMENT SOLUTION FOR BIOGAS PROCESSES

摘要

The invention relates to a trace element solution for supplementing nutrients for anaerobic fermentation, in particular a biogas method, comprising at least one trace element and at least two complexing agents. Complexing agents are used which can (1) transport trace elements in complexed form over the cell membrane and (2) release the trace elements into the cell. The complexing agents can optionally be biologically degraded.
