ABSTRACT

To improve the study of mixed microalgal populations, three naturally evolved marine microalgal cultures were subjected to a light crushing mechanical treatment using a silicon spatula coupled with zymolyase treatment at four concentrations: 5, 10, 20 and 25 U/ml, for 15, 30, 45 and 60 min before being observed under a microscope. The enzyme concentration of 20 U/ml after 45 min reduces the size of macroscopic microalgal aggregates and improves the microscopic observation of the different microalgal species comprising the population. There was no improvement using the higher enzyme concentration. This paper proposes a new approach to the study of naturally evolved microalgal populations which is useful for distinguishing the morphology of the different species present in the population and allowing for the identification by classical keys, and also to obtain a pure culture from an inoculum of mixed species by using a micromanipulator for cell counting.
