Effect on Growth of Desmodesmus sp Under Different Incubation Conditions
The aim of the research was to find the best conditions for selected microalgae species, Desmodesmus. sp in term of growth productivity in different pH, temperature and intensity of light. Desmodesmus. Sp (TRG-D01) was isolated from Setiu Wetlands, Terengganu and cultured using Bold Basal Media (BBM). The species was incubated under different selected parameters for nine days using microplate reader technique through Optical Density (OD) measurement. From the experiment, Desmodesmus. sp showed variety of growth pattern. Incubation under different pH, light intensity and temperature showed specific growth rate ranging from 0.21 to 0.47 d-1 (maximum OD 0.67 ̶ 0.93), 0.33 to 0.43 d-1 (maximum OD 1.12) and 0.12 to 0.42 d-1 (maximum OD=1.18) respectively. Desmodesmus. sp was optimum in were observed when incubated under pH in between 7 to 9, 56 to 91
