摘要

Abstract

Locations around the equator provide unique habitats for microalgae presumably with exceptional vitality. To develop microalga-derived product systems

we previously created a (sub)tropical microalgal collection. In this study

two

Chlorella

strains (MEM176 and MEM193)

adaptive to typical tropical climate

were isolated from the collection. The production performance was evaluated where both strains showed a robust growth in high temperatures and light intensities. Specifically

the strains MEM176 and MEM193 produced 503.6-mg/(L·d) and 411.3-mg/(L·d)

biomass

respectively

with high contents of proteins. Their commercial and nutritional values were emphasized by amino acid compositions (e.g.

proline

valine

and phenylalanine). Particularly

higher amounts of proline were revealed in MEM176 (47.9 mg/g dry biomass (DW)) and MEM193 (47.9 and 59.2 mg/g DW) than available commercial strains. Compar

ed with MEM193

MEM176 produced 129.7% more lipids in which unsaturated fatty acids (particularly linoleic acid and α-linolenic acid) account for 65% of the total lipids. Therefore

it is promising to explore the potential of these

Chlorella

strains as food additives via outdoor cultivation in tropical area

notably MEM176 that exhibits superiority as sources of essential amino acids and valuable fatty acids.
