BALAN, Andrea  and  PADILLA, Gabriel. New thermal inducible Streptomyces phages isolated from tropical soils. Braz. J. Genet. [online]. 1997, vol.20, n.4, pp.-. ISSN 0100-8455.

Two new Streptomyces phages, øBP1 and øBP2, were isolated from tropical soil samples. These phages presented a large host range and developed both lytic and lysogenic responses in different Streptomyces species tested. Variations in the incubation temperature showed to be important in the development of the replication cycle. Increasing incubation temperature from 30oC to 42oC induced the lytic response of øBP2 and lysogenic of øBP1 in the host strain Streptomyces sp. WL6. øBP1 and øBP2 have icosahedral heads with long tails and were characterized in relation to morphology, G + C content, genome size and adsorption curve
