The influence of spaceflight on Chlorella
1Academy of Sciences, USSR.
Abstract:
Three strains of Chlorella were investigated following spaceflight aboard Zond-5. Synchronized suspensions of Chlorella cells were grown in special containers. Each of these contained 0.1 X 10(6) cells. In the laboratory the strains LARG-1 and LARG-3 were examined microscopically. Nearly all the cells were in an autospore stage (94-98% for LARG-1 and 96-98% for LARG-3). Space effects on survival, mutation and cell development were studied. During the study of cell sporulation dynamics, the number of autospores resulting from the first sporulation was estimated. Percentage survival of the exposed cells is lower than that of the control. In the experimental material development of cells has been delayed and the percentage of visible mutations has been increased.
