Palm oil mill effluent (POME) released from conventional treatment systems poses severe environmental problems due to its dark color, its high chemical oxygen demand (COD), and high content of phenolic compounds. However, the possible biodegradation of phenolic compounds and color by microalgae was not well explored. This research aimed to reveal optimal conditions for pollutant removal through biodegradation by the cyanobacterium Arthrospira platensis. This species was grown under a range of POME fractions and environmental conditions (irradiance, salinity, nutrients) during which growth, final biomass, color, COD, and phenolic compound levels were followed. POME fractions influenced A. platensis growth rate, final biomass, COD, and color removal. The optimization of phenolic compound removal by using central composite design (CCD) response surface methodology (RSM) showed that low light and high initial phenolic compounds promoted the activity of A. platensis to degrade phenolic compounds. The combination of high initial phenolic compounds and high light intensity increased the growth rate up to 0.45 days⁻¹ and final biomass up to 400 mg L⁻¹, while total phenolic compounds were almost completely (94%) removed. Finally, this study showed that phenolic compounds and color degradation from POME were dominated by the activity of photodegradation at high irradiance, while the activity of A. platensis dominated at low light intensity.

常规处理系统释放的棕榈油厂废水（POME）由于其颜色深，化学需氧量（COD）高以及酚类化合物含量高而造成严重的环境问题。但是，尚未很好地研究微藻可能对酚类化合物和颜色进行生物降解。这项研究的目的是揭示最佳的去除污染物的方法，该污染物可以通过蓝细菌Arthrospira platensis进行生物降解。该物种在一定范围的POME馏分和环境条件（辐照度，盐度，养分）下生长，在此期间要跟踪生长，最终生物量，颜色，COD和酚类化合物的水平。POME馏分影响了A. platensis生长速率，最终生物量，COD和脱色。通过使用中央复合设计（CCD）响应表面方法（RSM）优化去除酚类化合物，结果表明，低光照和高初始酚类化合物促进了白僵菌降解酚类化合物的活性。高初始酚类化合物和高光强度的组合提高了生长速率，最高可达0.45天^-1天，最终生物量高达400 mg L ^-1，而总酚类化合物几乎被完全去除（94％）。最后，这项研究表明，在高辐照度下，光降解活性主要是由POME引起的酚类化合物和颜色降解，而板曲霉的活性却高。 在低光强度下占主导地位。
