Test of antimicrobial activity of Streptomyces massiliensis in vitro using streak cross method. a Evaluation of the inhibitory effect of S. massiliensis suspensions on different concentrations of EFAE: Enterococcus faecalis, MRSA: methicillin-resistant Staphylococcus aureus and MSSA: methicillin-susceptible Staphylococcus aureus. Suspensions of the test bacteria at 10⁴ CFU/mL were seeded for growth control across the entire width of the lower part of the petri dish. b Evaluation of the inhibitory effect of S. massiliensis on KPNE: Klebsiella pneumoniae; SEPI: Staphylococcus epidermidis; BCER: Bacillus cereus; CALB: Candida albicans; SM: Streptomyces massiliensis. Two deposits were realized for the test microorganisms, one in the upper part of the agar plate, perpendicular to the streak of S. massiliensis, to test the inhibitory effect of S. massiliensis and one streak in the lower part of the agar plate to control the growth of the test microorganisms
