We used the following bacterial species: Streptococcus agalactiae ATCC 12403, Staphylococcus aureus MRSA ATCC 43300, Klebsiella pneumoniae Extended Spectrum β-Lactamase (ESBL) ATCC 700603, Acinetobacter baumanii ATCC19606, and Enterococcus faecium (VRE) DSM17050. Bacteria were cultured at 37 °C/5% CO2 in liquid THY broth (Todd-Hewitt Broth, Oxoid, Hampshire, UK) supplemented with 0.5% yeast extract (BD, Miami, FA, USA). Pseudomonas aeruginosa PA14 (DSM 19882) was cultivated in liquid Müller–Hinton–Broth (Carl Roth, Karlsruhe, Germany) at 37 °C, under orbital shaking at 160 rpm.
In addition, the employed Mycobacterium tuberculosis ATCC 27294 (Mtb) was grown in 7H9-medium containing 7H9 BBL Middlebrook broth (BD), glycerol (Honeywell, Charlotte, NC, USA) OADC (Oelic Albumin Dextrose Catalase; BD), Tween 80 (Roth, Karlsruhe, Germany), and ddH2O. The pH was adjusted between 7.2–7.4 and sterile filtration was performed with a 0.2-µm filter membrane (Thermo ScientificTM NalgeneTM Rapid-FlowTM, Thermo Scientific, Bremen, Germany).

Four bacterial species and one yeast species were used to evaluate the antimicrobial activity of the putative AMPs. Pseudomonas aeruginosa ATCC 29213, Listeria monocytogenes ATCC BAA-679/EGD-e and Klebsiella pneumoniae ATCC 70,063 were cultured at 37 °C in a 5% CO2 atmosphere overnight as preculture inoculum in Todd–Hewitt broth. Yeast Candida albicans (ATCC 90028) was grown in Sabouraud dextrose medium at 37 °C for 48 h as preculture inoculum. Mycobacterium tuberculosis ATCC 27,294 was grown in 7H9 medium containing 7H9 BBL Middlebrook broth (BD), glycerol, OADC (Oelic Albumin Dextrose Catalase; BD), Tween 80 and ddH2O. The pH was adjusted between 7.2–7.4, and sterile filtration was performed with a 0.2 µm filter membrane (Thermo ScientificTM NalgeneTM Rapid-FlowTM; Thermo Fisher Scientific GmbH, Dreieich, Germany).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
