[Determination of radioresistance of microbes of different species irradiated separately and jointly].

Radioresistance of lactose positive and lactose negative Esch. coli, lactose positive Esch. coli and proteus, yellow sarcina and white staphylococcus, white and pink yeasts, white and yellow staphylococcus was studied after irradiation and seeding on hard media using separate and combined methods. In most cases radioresistance of the microbes did not depend of exposure conditions. However, lactose positive Esch. coli irradiated with proteus increased proteus radioresistance to its own standard. Yellow staphylococcus cannot form yellow pigment after irradiation with a dose of 1000 Gy.
