RESUMO
Bacteriophages lysing strains of Thermomonospora alba and T. fusca were isolated, following specific enrichment, from vegetable composts. Four Thermomonospora phages were distinguished by plaque morphology and host range. Electron microscopy of phage particles, termperature inactivation profiles, and electrophoretic analyses of major virion proteins and genomic DNA were used in the comparison and initial characterization of these phages. The four phages studied possessed polyhedral heads and long tails; genomes were linear double-stranded DNA molecules, 35 to 45 kilobases in length, which probably contain cohesive ends. Transfection of Thermomonospora protoplasts with purified genomic DNA from one of the phages was demonstrated.
