Abstract |
The aim of this study was to investigate the efficiency of thickness of optical panel (OP) on the growth rate of Chlorella vulgaris. The size of Chlorella vulgaris (FC-16) was 3-8 μm, having round in shape. The cells of Chlorella vulgaris was cultured in the Jaworski`s Medium with deionized water at 22℃ for 15 days. For this experiment, three OP samples were prepared to evaluate the efficiency of thickness of OP on the growth rate of Chlorella vulgaris; 4 mm OP with LED (Light Emitting Diode) (Run 1), 6 mm OP with LED (Run 2) and 8 mm with LED (Run 3). The diffuse rate was reached 86%, 91% and 92% for Run 1, Run 2 and Run 3, respectively. Average biomass of Run 2 and Run 3 were measured 11.18% higher than that of Run 1. However, the specific growth rate for all fractions were almost same. In addition, chlorophyll content per cell and cell volume were found to be slice difference between Run 2 and Run 3. Therefore, Run has more effect on growth rate of biomass for Chlorella vulgaris than Run 1 and Run 3. |
