- Abstract
Myxobacteria are considered as an important source of new antibacterial, antifungal, anticancer, antiparasitic, immunosuppressive, cytotoxic and antioxidative bioactive compounds. The importance of developing new antibiotics from natural sources is increasing because of an increase in diseases caused by antibiotic-resistant pathogens. In this study, 50 soil samples, four of which were from near thermal sources, and 6 water samples, four of which were from thermal sources, were collected from different provinces (Antalya, Burdur, Isparta, İzmir, Eskişehir, Bursa and Denizli, Turkey), and they were used for myxobacteria isolation. They belonged to five genus of myxobacteria; Myxococcus sp., Cystobacter sp., Stigmatella sp., Nannocytis sp., Polyangium sp. The antibacterial activities of myxobacteria isolates were investigated for Gram positive (Bacillus cereus ATTC 6051 and Staphylococcus aureus ATTC 25923) and Gram negative (Escherichia coli ATTC 25922 and Pseudomonas aeruginosa PA01) strains using the well diffusion method. myxobacteria isolates of MB23, MB33 andMB34 showed antibacterial effects against S. aureus (zone diameters of 22.0,24.7 and 19.3 mm, respectively) and myxobacteria isolates of MB9,MB23, MB28, MB33,MB34 against B. cereus (zone diameters of 10.0, 18.5, 10.0, 28.0 and 20.0 mm, respectively) but they had no activity against E. coli and P. aeruginosa. According to these results, it is important that the antibacterial activity of myxobacteria affects Gram positive pathogenic bacteria and detailed studies are required to understand their potential.
