Biological phenol degradation using microalgae-bacteria symbiosis

This research explores the phenol degradation efficacy of microalgal-bacterial co-culture (MBC) systems for phenolic wastewater under varying light intensities. Microbial community analysis revealed adaptive shifts, notably the increased abundance of specific microalgae and bacteria crucial to the phenol degradation process. The genus Parachlorella among microalgae exhibited the highest dominance due to its resistance to phenol toxicity. In contrast, the dominance of bacterial species varied significantly depending on light intensity and the characteristics of the seed community.

本研究探究了不同光照强度下，微藻-细菌共培养（microalgal-bacterial co-culture, MBC）系统对含酚废水的苯酚降解效能。微生物群落分析结果显示，群落结构发生适应性演替，其中对苯酚降解过程至关重要的特定微藻与细菌类群的丰度显著提升。在微藻类群中，拟小球藻属（Parachlorella）因具备苯酚毒性抗性，展现出最高的群落优势度。与之相对，细菌物种的群落优势度则随光照强度以及接种群落的特征发生显著变化。
