The biosorption of phenol on non-living lyophilized mycelial pellets of Phanerochaete chrysosporium cultivated in liquid medium of various compositions was studied in batch biosorption system. The fungal cell surfaces were characterized by FTIR spectroscopy and specific surface charge determination. The sorption kinetics and equilibrium were evaluated using linear and non-linear regression. For adsorption equilibrium, a comparative evaluation is also presented using non-linear least-square estimation and linearization of the Langmuir and anti-Langmuir equations. The presence of mineral and vitamin materials in the liquid medium enhanced the adsorption capacity of fungal biomass for phenol. At optimum pH 5-6, the values of specific surface charge were 0.023 and 0.069 meq g for various cultivations, and the maximum amounts of phenol can be adsorbed at these pH values. The maximum adsorbed phenol amounts by cells cultivated in simple and complex media were 4.53 and 13.48 mg g, respectively, at an initial phenol concentration of 100 mg l. Graphical abstract ᅟ.
在分批生物吸附系统中研究了在不同组成的液体培养基中培养的非活体冻干白腐真菌（Phanerochaete chrysosporium）菌丝体球粒对苯酚的生物吸附。通过傅里叶变换红外光谱法和比表面电荷测定对真菌细胞表面进行了表征。通过线性和非线性回归评估了吸附动力学和平衡。对于吸附平衡，还使用非线性最小二乘估计和朗缪尔和反朗缪尔方程的线性化对其进行了比较评估。液体培养基中矿物质和维生素材料的存在提高了真菌生物质对苯酚的吸附能力。在最佳 pH 值 5-6 时，不同培养条件下的比表面电荷值分别为 0.023 和 0.069 meq g，并且在这些 pH 值下可以吸附最大量的苯酚。在初始苯酚浓度为 100 mg l 时，在简单和复杂培养基中培养的细胞分别可以吸附 4.53 和 13.48 mg g 的最大苯酚量。
