Starvation increases the susceptibility of Paramecium and Colpidium to ultraviolet (UV) radiations (Giese and Reed, 1940; Giese et al., 1954). Injury to starved colpidia is found to be less readily photoreversed than that to well fed animals, eight times as many quanta of blue light per quantum UV being required for maximal photoreversal (Giese et a/., 1953). Refeeding them with bacteria after UV but before blue light has little effect upon the degree of photoreversal (Giese eta/., 1954). Since…

PHOTOREACTIVATION IN COLPIDIUM COLPODA

Colpidium colpoda, grown on a single strain of bacteria in 0.05% lettuce medium buffered at pH 7, was irradiated with various wave-lengths of monochromatic ultraviolet (UV) light and the retarding effects were progressively greater with increasing dosages until division of treated colpidia was prevented.

QUANTUM RELATIONS IN PHOTOREACTIVATION OF COLPIDIUM

Photoreactivation seems to be a balance between the slight injurious effect produced by the visible light or UV of long wave lengths and the injury produced by short wave length UV.

The Effects of Starvation on Photoreactivation in Colpidium colpoda

The effects upon photoreversal of varied environmental conditions and of postirradiation nutritive conditions have been studied.
