| 总结: | Microalgae lipid is a promising feedstock for biodiesel
production. The objective of this work was to study growth factors affecting marine mutant Synechococcus sp.(PCC 7002) for high lipid production. Four growthfactors were investigated; nitrogenphosporus-potassium (NPK)concentration, light intensity,temperature and NaNO3concentration on mutant strain growth and
lipid production were studied. Design Expert v8.0 was used to design the experimental and analyze the data. The experimental design selected was Min-Run Res IV which consists of 12 runs and the response surfaces measured were specific growth rate and lipid concentration. The extraction of lipid was conducted by chloroform/methanol solvents system. Based on the study, mutant Synechococcus sp.PCC 7002 gave the highest specific growth rate of 0.0014 h-1 at 0% NPK, 2500 lux, 40oC and 0% NaNO3. On the other
hand, the highest lipid concentration was obtained at 0% NPK, 3500 lux, 30oC and 1% NaNO3. |
