Xiao, Meng published the artcileEffect of hydroxypropyl-β-cyclodextrin on the cometabolism of phenol and phenanthrene by a novel Chryseobacterium sp., Application of 1-Hydroxy-2-naphthoic acid, the publication is Bioresource Technology (2019), 56-62, database is CAplus and MEDLINE.
Cometabolic degradation is an effective method to remove the polycyclic aromatic hydrocarbons (PAHs) with phenol as growth substrate from coal chem. wastewater (CCW). Unfortunately, the toxicity and low solubility of PAHs always restrict their degradation In this study, Chryseobacterium sp. H202 was firstly isolated from the aerobic segment of CCW. Then, to improve the cometabolic degradation of PAHs, the effects of hydroxypropyl-β-cyclodextrin (HPCD) were investigated. Phenanthrene removal was accelerated in the presence of phenol; however, the degradation of phenol was inhibited because of the toxicity of phenanthrene. Addition of 50 mg/L HPCD accelerated the degradation of phenol and effectively improved the phenanthrene removal rate by about 55%. Inclusion of HPCD appeared to increase the apparent solubility and reduce the toxicity of phenanthrene, thereby improving the cometabolic degradation of phenol and phenanthrene. Therefore, HPCD can enhance the degradation of phenanthrene with phenol as the growth substrate during CCW treatment.
