Ultraviolet radiation response of two heterotropy Antarctic marine bacterial; Respuesta a la radiacion ultravioleta de dos cepas bacterianas marinas heterotrofas antarticas

Abstract

Two Antarctic marine bacterial strains, were exposed to different irradiance of ultraviolet (UV) solar radiation using several experimental protocols and interferential filters. Results showed that both, UV-A and UV-B radiation produce deleterious effects on two tested bacterial strains. The mortality values under UVB treatments were higher than those observed under UVA treatments. UVvi strain proved to be more resistant to UV radiation than the UVps strain.

Los resultados mostraron que tanto la radiacion UV-A como UV-B produce efectos deletereos sobre las dos cepas bacterianas analizadas. Los valores de mortalidad bajo tratamiento UV-B fueron mayores que los observados bajo tratamiento UV-A. La cepa UVvi mostro mayor resistencia a la radiacion UV que la cepa UVps. (autor)
