NTUシンガポールの科学者は、一般的な微細藻類の一種から植物由来の油を効率的に生産・抽出する方法を開発しました。
微細藻類から生産された油は食用に適し、パーム油と同様の優れた特性を持っているため、今回発見された方法はパーム油に代わるより健康的で環境に優しい油として役立つと期待されます。

Abstract

A two-stage screening approach of chemical inducers was carried out to evaluate the positive effect on enhancing astaxanthin and lipid production in mixotrophic Chromochloris zofingiensis. The results demonstrated that oxidants were able to increase the astaxanthin content high up to 11.4 mg g-1 biomass, while pyruvic acid promoted the cell growth and increased the contents of astaxanthin and lipids up to 10.7 mg g-1 and 66.1% dry weight. The highest yield (87.0 mg L-1) and productivity (7.3 mg L-1 day-1) of astaxanthin were obtained in parallel with high lipid productivity (459.0 mg L-1 day-1). The correlations between the dosage effect of chemical inducers and metabolites variation were further examined by statistical analyses. Additionally, C. zofingiensis-derived lipids were estimated to be more viable and feasible as edible oils based on fatty acid characteristics assessment. The present work highlights the effective screening strategy of chemical inducers for enhancing astaxanthin and lipid production and the potential application in mixotrophic C. zofingiensis.
