Abstract

Growth substrate is a platform that supplements nutrient for the cultivation and the growth of marine microalgae of pure culture genera in a laboratory environment. Conway and f/2 media are commonly used as the growth substrate for such cultivation. A study was performed to determine the effect of Conway and f/2 media on the growth of microalgae genera. Genera of Chlorella, Dunaliella, Isochrysis, Chaetoceros, Pavlova and Tetraselmis were isolated from the South China Sea. Each genus was individually cultured using Conway and f/2 Media as their growth substrate. During the cultivation period, the density of cells was determined using Syringe Liquid Sampler Particle Measuring System (SLS-PMS) that also generated the population distribution curve based on the size of the cells. The population of the microalgae genera is thought to consist of mother and daughter generations since these microalgae genera reproduce by releasing small non-motile reproductive cells (autospores). It was found that the reproduction rate of Tetraselmis, Dunaliella and Pavlova could be sustained longer in f/2 Medium. Higher cell density was achieved by genus Dunaliella, Chlorella and Isochrysis in Conway Media. Different genera of microalgae had a preference for different types of cultivation media.
