Notes.

Meaning of score values derived from MALDI/TOF mass spectrometry are as follows:

-Values in the range of 2.300–3.000 denote the highly probable species identification (represented in green).

-Values in the range of 2.000–2.299 denote the secure genus identification, probable species identification (represented in green).

-Values in the range of 1.700–1.999 denote the secure genus identification (represented in yellow).

-Values in the range of 0.000–1.699 denote the unreliable identification (represented in red).
