In this study oil was extracted from Pinus nigra subsp. pallasiana, Abies normanniana subsp. equi-trojani, Pinus sylvestris, Picea orientalis, Pinus brutia and Cedrus libani then tested against Gram-positive bacteria: Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecium, Enterococcus faecalis, Klebsiella pneumoniae and Bacillus subtilis. Gram-negative bacteria: Salmonella typhimurium, Salmonella kentucky, Salmonella infantis, Salmonella enteritidis, Escherichia coli, Enterobacter aerogenes, Pseudomonas aeruginosa and Pseudomonas fluorescens, and fungi; Candida albicans.eninfo:eu-repo/semantics/openAccessPinus nigra subsp. pallasiana, Abies normanniana subsp. equi-trojani, Pinus sylvestris, Picea orientalis, Pinus brutia, Cedrus libani, Antimicrobial, Essential oil, GC-MS analysisThesis
