The successes made in the production of algal high-value products in the last decades are threatened by the continuous rise in global temperature to which most strains are not fully adapted. The choice of strains adapted to high temperatures from novel locations with excellent potential to produce high concentrations of biomolecules such as lipids, carbohydrates, pigments, and antioxidants is extremely important and requires continuous exploration. In the present study, strains Chlorella lewinii KU220 JNI1, Chlorella sp. NEIST JNI3, Chlorella lewinii KU217 JNI6, and Chlorella sp. NC JNI8 were characterized for the quantity and quality of lipids and fatty acids, pigments, carbohydrates, and proteins at 20, 25, and 30°C. The highest biomass (cell densities and ash-free dry weight), chlorophylls, and carotenoids production occurred at 25 and 30°C. Regardless of the growth temperature, total lipids, total carbohydrates, and total protein levels ranged from 12.96 to 51.11% of ash-free dry weight. Palmitic acid (C16:0) and stearic acid (18:0) were the predominant fatty acids in the strains irrespective of temperature conditions. With such high levels of fatty acid saturation and biodiesel characteristics, the lipids were best suited for bioenergy purposes. The excellent general performance of the strains under the different temperature treatments means they are adapted for bioenergy and food applications in areas with variable and rising temperatures.

在过去几十年中，藻类高价值产品的生产成功受到全球温度持续升高的威胁，大多数菌株无法完全适应该温度。从具有高潜力生产高浓度生物分子（如脂质，碳水化合物，色素和抗氧化剂）的新位置选择适应高温的菌株极为重要，需要不断探索。在本研究中，菌株Lewinii Lewinii KU220 JNI1，Chlorella sp.。NEIST JNI3，小球藻KU217 JNI6和小球藻sp。NC JNI8的特征在于在20、25和30°C下脂质和脂肪酸，色素，碳水化合物和蛋白质的数量和质量。最高的生物量（细胞密度和无灰干重），叶绿素和类胡萝卜素的产生发生在25和30°C。不论生长温度如何，总脂质，总碳水化合物和总蛋白质含量为无灰干重的12.96％至51.11％。棕榈酸（C16：0）和硬脂酸（18：0）是菌株中的主要脂肪酸，与温度条件无关。具有如此高的脂肪酸饱和度和生物柴油特性，脂质最适合用于生物能源。
