Control of temperature is a major challenge for industrial microalgae production in photobioreactors outdoors. Strains with tolerance for high temperatures can reduce the cost of production as active temperature control is not required. In this study, marine photoautotrophic microorganisms were isolated to reduce the need for control of high temperature.

Twenty-two samples were taken from different saline waters on the Caribbean island Bonaire. During strain enrichment, a temperature of 40 °C was used as selective pressure and strains with the highest growth rate were selected. We isolated and identified 59 strains, after which 5 were selected for characterization on growth rate and biomass composition. Picochlorum sp. and Leptolyngbya sp. showed optimal growth at 40 °C and 35 °C with a growth rate of 0.12 h⁻¹ during daytime, respectively. The strains contain 62.1% and 68.2% of protein and have varying fatty acid compositions suitable for application as edible oil and biofuel.

温度的控制是户外光生物反应器中工业微藻生产的主要挑战。耐高温菌株可以降低生产成本，因为不需要主动温度控制。在这项研究中，分离了海洋光合自养微生物以减少控制高温的需要。

从加勒比岛博内尔岛的不同盐水中采集了22个样品。在菌株富集期间，将40°C的温度用作选择压力，并选择生长速率最高的菌株。我们分离并鉴定出59株，然后选择5株以表征生长速率和生物量组成。Picochlorum SP。和Leptolyngbya sp。在白天分别在40°C和35°C时以0.12 h ^-1的生长速率表现出最佳生长。该菌株含有62.1％和68.2％的蛋白质，并具有适合用作食用油和生物燃料的各种脂肪酸组成。
