Abstract

The constant increase in demand for food, valued bio-based compounds and energy demand has prompted the development of innovative and sustainable resources. New technologies and strategies must be implemented to boost microalgae biomass production, such as using different photoperiods along with (LED) light-emitting diodes to stimulate biomass production and boost profits. This work investigates the cultivation of blue-green microalgae (Spirulina) in a closed lab condition. The current study aims to boost Spirulina biomass production by creating ideal growth conditions using different photoperiods (12:12; 10:14; 14:10) light/dark with a constant light intensity of 2000 lx from White LED lights. The obtained optical density and protein content was highest for photoperiod 14L: 10D and values were 0.280 OD, with a protein content of 23.44 g/100 g, respectively. This study is a crucial first step in identifying the best photoperiod conditions to help S. platensis produce more biomass. The study results showed that increasing photoperiod for S. platensis farming can improve the quality and amount of biomass generated in those cultures without negatively affecting growth.

光周期和白光LED对螺旋藻生物量生长和蛋白质产量的影响。

对食物、有价值的生物基化合物和能源需求的不断增长，促使了创新和可持续资源的开发。必须实施新的技术和战略来促进微藻生物质生产，例如使用不同的光周期和（LED）发光二极管来刺激生物质生产和提高利润。本文研究了蓝绿微藻（螺旋藻）在封闭实验室条件下的培养。目前的研究旨在通过使用不同的光周期（12:12;10:14;14:10）光/暗，在白光LED灯的恒定光强为2000 lx的情况下，创造理想的生长条件来促进螺旋藻生物量的生产。光周期为14L: 10D时光密度和蛋白质含量最高，分别为0.280 OD，蛋白质含量为23.44 g/100 g。这项研究是确定最佳光周期条件的关键的第一步，以帮助白杨产生更多的生物量。研究结果表明，增加光周期可以在不影响柽柳生长的前提下提高柽柳生物量的质量和数量。
