摘要

Five nominally freshwater microalgae (Chlorella vulgaris, Choricystis minor, Neochloris sp., Pseudococcomyxa simplex, Scenedesmus sp.) with a known ability to produce high-levels of lipids for possible use as fuel oils were evaluated for their ability to thrive and produce lipids in seawater and brackish water. Only C. vulgaris was found to thrive and produce lipids in full strength seawater. Seawater tolerant strains of C. vulgaris are unusual. Lipid productivity in nutrient sufficient seawater exceeded 37 mg L-1 d(-1) and was nearly 2-fold greater than in freshwater. Although other microalgae such as C. minor had higher lipid productivities (e.g. 45 mg L-1 d(-1)), they did not thrive in seawater. The lipid content of the C. vulgaris biomass was nearly 16% by dry weight. The calorific value of the seawater-grown C. vulgaris biomass exceeded 25 kJ g(-1). Compared to continuously illuminated cultures, a 12/12 h light-dark cycle reduced lipid productivity of C. vulgaris by similar to 30%, but did not affect the lipid content of the biomass. Biomass yield on phosphate was nearly 27% higher in seawater compared to in freshwater. While C. vulgaris has been extensively studied in freshwater, it has not been examined to any detail in full strength seawater. Studies in seawater are essential for any future large scale production of algal oils for biofuels: seawater is available cheaply and in large amounts whereas there is a global shortage of freshwater.

Ventgaris在淡水中被广泛研究，但尚未在全强力海水中进行任何细节。海水的研究对于生物燃料的任何未来大规模产量的藻类生产的研究是必不可少的：海水可廉价，大量可用，而全球淡水缺少。 （c）2016年Elsevier B.v.保留所有权利。
