Affiliation 4 and affiliation 5 are incorrectly switched. The affiliation for João Lopes should be: Departamento de Tecnologia Farmacêutica, Faculdade Farmácia, Universidade de Lisboa, Lisboa, Portugal. The affiliation for Manuela E. Pintado should be: CBQF, Centro de Biotecnologia e Química Fina, Escola Superior de Biotecnologia, Universidade Católica Portuguesa, Porto, Portugal.

The images for Figures 1 and 2 are incorrectly switched. The image that appears as Figure 1 should be Figure 2, and the image that appears as Figure 2 should be Figure 1. The figure legends appear in the correct order. Please view the correct images for Figure 1 and Figure 2 here.

Figure 1. Average mass spectra obtained by MALDI-TOF-MS analysis of B. pumilus and B. safensis isolates.

(a) B. pumilus (5 spectra) and (b) B. safensis (22 spectra) in the ion range atm/z 2000 to 12000. Spectra were obtained by averaging the respective experimental ion signals from all isolates.
