Antibacterial activity of bacterial isolates of soil bacteria collected from Palestine

A total of 51 Actinomycetes were isolated from different soil samples of Palestine. Preliminary screening by cross-streak method was carried out for all the 51 isolates. After preliminary screening, 17 isolates which showed antimicrobial (antibacterial, antifungal) activity were selected for further study. Among these 17 isolates tested, 5 isolates which were found to be promising were subjected to detailed taxonomic studies. A novel strain of S. albovinaceus (isolate 10/2) which was found to be maximum antibiotic producer and which has shown both broad spectrum antibacterial and antifungal activities was isolated and is been selected for further detailed optimization studies.
