Evolution in the photosynthetic oxygen rate of a Cd-resistant strain of Dictyosphaerium chlorelloides by changes in light intensity and temperature.

Environmental factors such as temperature and light are the most determinants in the photosynthetic productivity in microalgae. However, under extreme of these conditions, certain resistant microalgae strains possess additional abilities such as growth in the presence of high concentrations of metals and some can improve in combinations of more than one abiotic stress. Therefore, the aim of this research was to evaluate the efficiency in photosynthetic production through the oxygen balance to variations in photon intensity, and under temperature changes in a Cd-resistant strain (Dc) compared to the wild-type strain (Dc1M) of Dictyosphaerium chlorelloides.
