✦ Synopsis

Eudorina elegans does not respond to liquid-holding or to postirradiation medium effects by changes in recovery.

A decrease in survival ability is observed ff a culture is starved prior to irradiation, or is incubated at 22~ rather than 32~ following UV irradiation.

Eudorina loses the ability to photoreaetivate UV damage within 10 to 48 h following irradiation, depending upon the pre-and post-UV culture conditions.

The results are interpreted as indicating a failure of Eudorina elegans to carry out specific dark repair of UV damage. Some reactivation may occur during cellular DNA synthesis.
