Abstract
The influence of UV and .gamma.-radiations on H. samuelpessoai grown either in a chemically defined or in a complex medium was studied. Cells cultivated in defined medium were inhibited more by UV than those from complex medium. The effect of .gamma.-radiation was independent of the cell growth media. Both radiations interfered with the plasma membrane as analyzed by parameters such as excretion of cellular material and concanavalin-A-induced agglutination. Doses of UV which inhibit the cellular growth do not interfere with the plasma membrane. With .gamma.-radiation, doses which inhibit cellular growth also interfere with the plasma membrane. For certain applications UV radiation may be an advantage in vaccine production.This publication has 8 references indexed in Scilit:
