摘要

空气污染物的增加大大加剧了气候变化,因此需要创新的减缓战略。微藻通过吸收二氧化碳和农业和工业排放的氮氧化物(NOx)、硫氧化物(SOx)和氨等污染物,同时产生用于生物燃料和动物饲料的生物质,提供了一种很有前途的解决方案。研究了光强对在光生物反应器中培养的Scenedesmus sp. AQUAMEB-57、Ankistrodesmus sp. AQUAMEB-33和Synechococcaceae AQUAMEB-32的生长和生化组成的影响。在200µmol光子m-2s-1时,Scenedesmus sp.的细胞浓度最高(8 × 106个细胞ml-1), Ankistrodesmus sp.和Synechococcaceae的细胞浓度最高,为300µmol光子m-2s-1。在300µmol光子m-2s-1时,所有物种的干生物量最高。光强为200µmol光子m-2s-1时,Scendesmus sp.的蛋白质含量最高(15.6%),300µmol光子m-2s-1时,Ankistrodesmus sp.的蛋白质含量为17.2%,100µmol光子m-2s-1时,Synechococcaceae的蛋白质含量为23.5%。在300µmol光子m-2s-1条件下,场景菌、Ankistrodesmus sp.和聚菌科的最大碳水化合物含量分别为56.0%、20.5%和18.4%。当光强从100µmol光子m-2s-1增加到200µmol光子m-2s-1时,C16/C18脂肪酸显著增加。结果表明,光照强度会影响植物的生长速率和生化特征,且随品种和栽培方式的不同而不同。连续系统比间歇系统产生更高的生物量,强调需要优化策略来提高藻类生产力。这项研究增强了对微藻生长动态的理解,为优化条件以提高生物质产量和支持可持续的生物燃料生产和其他有价值的产品提供了见解。

Growth performance of Scenedesmus sp. AQUAMEB-57. Ankistrodesmus sp. AQUAMEB-33, and Synechococcaceae AQUAMEB-32 cultivated at different light intensities.

Increasing air pollutants significantly contributes to climate change, requiring innovative mitigation strategies. Microalgae provide a promising solution by absorbing CO₂ and pollutants like nitrogen oxides (NOx), sulfur oxides (SOx), and ammonia from agricultural and industrial emissions, while also generating biomass for biofuels and animal feed. This study investigated the effects of light intensity on the growth and biochemical composition of Scenedesmus sp. AQUAMEB-57, Ankistrodesmus sp. AQUAMEB-33, and Synechococcaceae AQUAMEB-32 cultivated in photobioreactors under two batch and continuous culture conditions. Scenedesmus sp. reached the highest cell concentration (8 × 106 cells ml-1) at 200 µmol photons m-2s-1, while Ankistrodesmus sp. and Synechococcaceae peaked at 300 µmol photons m-2s-1. Dry biomass was highest for all species at 300 µmol photons m-2s-1. Scendesmus sp showed the highest protein content (15.6%) at a light intensity of 200 µmol photons m-2s-1, Ankistrodesmus sp. (17.2%) at 300 µmol photons m-2s-1, and Synechococcaceae (23.5%) at 100 µmol photons m-2s-1. Maximum carbohydrate content for Scenedesmus sp., Ankistrodesmus sp., and Synechococcaceae was 56.0%, 20.5%, and 18.4%, respectively, at 300 µmol photons m-2s-1. C16/C18 fatty acids significantly increased as light intensity was raised from 100 to 200 µmol photons m-2s-1. The findings show that light intensity impacts growth rates and biochemical profiles, varying by species and cultivation mode. Continuous systems yield higher biomass than batch systems, emphasizing the need for optimized strategies to enhance algal productivity. This research enhances understanding of microalgal growth dynamics, offering insights into optimizing conditions for improved biomass yield and supporting sustainable biofuel production and other valuable products.
