摘要

本研究探讨了高价值微藻（小球藻（Chlorella vulgaris， C.）和Scenedesmus （S.)）与丝状微藻（Tribonema， T.）和Lyngbya (L.)）共培养对奶牛废水（DW）修复和提高生物质产量和收获的可行性。结果表明：与单作相比，生物量生产力提高了12-174%，最佳组合为S:T。该组合获得了最高的生物量生产力84.25 mg L−1 d−1，同时去除86.7%的化学需氧量（COD）， 88.7%的NO3−-N和98.5%的PO43—P。本研究还测试了收获时间对生化成分积累的影响，发现收获时间分别为第9天和第11天，碳水化合物和脂质产量最高。此外，微藻联盟S:T实现了78.5%的高生物量回收率，而S:T单独获得了32.4%，突出了其有效修复DW和资源回收的潜力。

Co-cultivation of high-value microalgae species with filamentous microalgae for dairy wastewater treatment

The study examined the feasibility of co-culturing high-value microalgae sp. (Chlorella vulgaris (C.), and Scenedesmus (S.)) with filamentous microalgae sp. (Tribonema (T.) and Lyngbya (L.)) to remediate dairy wastewater (DW) and enhance biomass production and harvesting. The results showed that biomass productivity increased by 12‒174% compared to monocultures, and the best consortium was S:T. This consortium achieved the highest biomass productivity of 84.25 mg L−1 d−1 while removing 86.7% of chemical oxygen demand (COD), >88.7% of NO3−-N and >98.5% of PO43–-P. The study also tested the effect of harvesting time on the accumulation of biochemical components and found the optimal harvesting times of day 9 and day 11 to achieve maximum carbohydrate and lipid productivity, respectively. Additionally, the microalgae consortium S:T achieved a high biomass recovery of 78.5%, compared to 32.4% obtained for S. alone, highlighting its potential for efficient DW remediation and resource recovery.
