摘要
Phenolic compounds are toxic and dangerous to the environment and human health. Although the removal of phenols and their derivatives is very difficult, it has been achieved by applying some biological processes. The capacity of microalga to remove phenolic compounds has been demonstrated; however, few reports of the removal of these compounds in a mixture have been published. The removal of phenol, p-cresol and o-cresol was performed by batch kinetics at 50 and 100 mg L−1, and the simultaneous degradation of phenol, p-cresol and o-cresol was carried out in a mixture at 40 mg L−1 using the marine microalga Tetraselmis suecica. The kinetic study was carried out for 192 h. For concentrations of 50 mg L−1 and 100 mg L−1, phenolic compound consumption efficiencies greater than 100% and 85%, respectively, were obtained, and up to 73.6% removal in the mixture. The results obtained indicate that the marine microalga carries out a process of the oxidation of organic matter and phenolic compounds, mineralizing up to 31.4% to CO2 in the mixture. Biological treatments using the marine microalga T. suecica can be considered feasible to treat effluents with concentrations similar to those of the present study.

酚类化合物对环境和人类健康有毒和危险。尽管去除酚及其衍生物非常困难，但通过应用一些生物学过程来实现。已经证明了Microalga去除酚类化合物的能力；但是，很少有关于混合物中去除这些化合物的报道。通过批次动力学在50和100 mg l-1的批次动力学中去除苯酚，p- cresol和o-cresol，并同时在40 mg l l的混合物中在混合物中同时降解苯酚，p- cresol和o-cretol -1使用海洋Microalga Tetraselmis Suecica。动力学研究进行了192小时。对于50 mg L -1和100 mg L -1的浓度，获得大于100％和85％的酚类化合物消耗效率，并在混合物中除去73.6％。获得的结果表明，海洋Microalga进行了有机物和酚类化合物的氧化过程，在混合物中矿化高达31.4％。使用海洋微层链球菌的生物学处理可被认为可行，可以治疗与本研究相似的浓度的废水。
