Abstract
Temperate and virulent bacteriophages isolated from soil were shown to carry out generalized transduction of Bacillus stearothermophilus NUB36. A transducing frequency of 1 X 10(-5) to 7 X 10(-4) was obtained for temperate phages TP-42 and TP-56. The transducing frequency for virulent phage TP-68 was two to three orders of magnitude lower. Cotransfer analysis with the three phages showed that hom-1 is linked to thr-1 and that gly-1 is linked to his-1.
