TOXIC EFFECTS OF MICROPLASTICS ON SACCHAROMYCES CEREVISIAE CELL GROWTH IN CULTURE MEDIU
by Sayako Markrich
Abstract – Polystyrene, a world-wide commonly used plastic, has been found polluting both aquatic and terrestrial environments. Its ability to disrupt food chains has led to an investigation to evaluate whether polystyrene will affect yeast cell (Saccharomyces cerevisiae) populations. In this study, yeast cells were subject to different structural forms (surface area) and masses of polystyrene within agar plates, to assess cell growth. Based on the calculated results, it is suggested that polystyrene pellets may cause an inhibition in yeast cell population growth, and among all treatment groups, the fragmented group had the highest inhibition of yeast cells.
