The objective of this study was to identify and separate 
Streptomyces rochei-specific actinophages. From two 
different sites of reclaimed soil in the Sohag Governorate 
region, eight actinophage (streptomyces phage) isolates 
specifically for Streptomyces rochei were successfully 
identified. The samples were taken from reclaimed soil in 
Alkawmel city and the New Sohag experimental farm of the 
Faculty of Agriculture, Sohag University, in Sohag, Egypt. 
All of the isolated phages (the actinophage) looked to be 
head-and-tail types, according to electron micrographs of 
the isolated phages. The eight isolates of the phage were 
given the numbers 1, 2, 3, 4, 5, 6, 7, and 8. Each phage 
isolate's heat inactivation point was investigated. Although 
all phage isolates maintained their infectivity at 85 °C 
during 10 minutes, they all demonstrated resistance to high 
temperatures. It has been discovered that a pH of 7 is ideal 
for phage infection, while phage isolates can survive in both 
alkaline and acidic environments. The susceptibility of the 
different phage isolates to UV light varies.
