Displacement of bacterial communities within the NMDS plot (Stress <0.01). Complex N-enrichments were tryptophan (open triangle), nutrient broth (open diamond), urea (open inverted triangle), and bacterial protein (open circle). Simple N-enrichments were glycine (filled triangle), ammonium (filled circle), nitrate (filledĀ inverted triangle), and defined-N mixture (filled diamond)
