| Abstract |
These research investigated the microalga Scenedesmus sp. KKU-P2 cultivation under mixotrophic condition. Firstly, the capability of sugars utilization of Scenedesmus sp. KKU-P2 were examined in 3N Bold basal medium (3N-BBM) supplemented with various types of sugar. The cultivation was conducted in 96 wells plate illuminated with light from light emitting diode (LED) or fluorescent lamp at 3,000 lux. Glucose was the most suitable sugar for Scenedesmus sp. KKU-P2 growth followed by fructose while xylose showed an inhibitory effect. Light source did not affect the growth of Scenedesmus sp. KKU-P2. Subsequently, the influences of initial pH on growth of Scenedesmus sp. KKU-P2 were further investigated using molasses as carbon source at the total sugar concentration of 3 g/L. The experiments were conducted in 500 mL-flasks with the working volume of 200 mL. Scenedesmus sp. KKU-P2 could grow in a wide range of initial pH from 5.0 to 9.0 of which pH 9.0 was optimum for Scenedesmus sp. KKU-P2 growth giving maximum biomass concentration of 1.32 g/L with 63% sugar consumption. The microalgal biomass yield was 0.66 g/g-sugar consumed. |
