摘要
利用微藻固定二氧化碳(CO2)是一种前景广阔的二氧化碳捕获和利用技术。微藻也被认为是一种潜在的沼气浆(BS)处理方法。本研究筛选了能够耐受高浓度 CO2 和 BS 的微藻,评估了它们固定 CO2 和去除污染物的能力,并评估了所产生的藻类生物量的潜在用途。Chlamydopodium sp. HS01 对 15% CO2 和 BS 的耐受性最高,因其生长旺盛、二氧化碳固定和氨氮去除能力强而被选中。所产生的生物质也显示出生产生物能源的巨大潜力。代谢组学分析表明,HS01 的脂质组成在单独和与 BS 结合的 15% CO2 条件下发生了很大变化,这可能是一种胁迫适应策略。总之,HS01 具有利用二氧化碳和实际 BS 资源的巨大潜力。
Simultaneous CO2 and biogas slurry treatment using a newly isolated microalga with high CO2 tolerance
The fixation of carbon dioxide (CO2) using microalgae is a promising CO2 capture and utilization technology. Microalgae have also been suggested as a potential treatment for biogas slurry (BS). This study screened microalgae capable of tolerating both high CO2 concentrations and BS, assessed their CO2 fixation and pollutant removal capabilities, and evaluated the potential use of the resulting algal biomass. Chlamydopodium sp. HS01, which showed the highest tolerance to 15% CO2 and BS, was selected due to its strong growth, CO2 fixation, and ammonia nitrogen removal abilities. The generated biomass also demonstrated significant potential for bioenergy production. Metabolomics analysis revealed that the lipid composition of HS01 underwent substantial changes under 15% CO2 alone and in combination with BS, likely as a stress adaptation strategy. Overall, HS01 presents high potential for resource utilization of CO2 coupled with actual BS.
