Effect of Electrolysis Treatment Time, Field Strength and Recycling Flowrate on Ankistrodesmus sp. Lipid Extraction
2019
Costantine Joannes
The study discusses the effect of Electrolysis Ereatment (ET) parameters focussed on the Electrolysis Treatment Time (ETT), Electrolysis Field Strength (EFS) and Electrolysis Recycling Flowrate (ERF) towards Ankistrodesmus sp. lipid extraction prior to the solvent extraction method. In the ET system selection experiment, the highest lipid content (13.05 ± 0.57 % wt.) attained was from ET system 3 (21V/cm, 140ml/min and 25 min). The three ET parameters were then optimized. The highest lipid content and methyl palmitate gained in ETT was 15.83 ± 0.68 % wt. and 0.440 ± 0.046μg/ml at 20 min, respectively. Meanwhile, the highest lipid content and methyl palmitate obtained in EFS was 15.46 ± 0.78 % wt. and 0.629 ± 0.058μg/ml at 21V/cm, respectively. As for ERF, the highest lipid content and methyl palmitate attained was 15.60 ± 0.67 % wt. and 0.390 ± 0.032μg/ml at 180ml/min, respectively. In comparison to Ankistrodesmus sp. Without Electrolysis Treatment (WOET), the lipid extraction of Ankistrodesmus sp. treated With Electrolysis Treatment (WET) can be improved and had resulted in the increasing of extraction with 1.34, 1.38 and 1.40 times higher in ETT, EFS and ERF, respectively.
