Abstract:
A total number of 64 bacterial strains isolated from two volcanic tuff rock located in Teisani, Prahova, and Malul Alb, Buzau areas were investigated for ability to producing factor with antagonistic activity (AF). From these, 59 strains have the ability to synthesis AF acting against other strains isolated from these ecosystems. Some of the strains (1-2 and 1-7 respectively, isolated from Malul Alb) are acting as antimicrobial against pathogenic strains Staphyloccocus aureus and Lysteria monocytogenes. Fourier Transform Infrared Spectroscopy (FTIR) and X-Ray fluorescence (XRF) analysis revealed a chemically composition based on the compounds of silica, calcium, potassium, aluminum, iron and
titanium as well as the presence of groups characteristic to organic compounds. A relatively high number of microbial strains as colony-forming units (CFU) were quantified at 7x104 for the Teişani sample and 1.5x105 for the Malul Alb sample per gram of rock.
