Key microbial populations involved in anaerobic degradation of phenol and p-cresol using different inocula

Franchi, Oscar; Rosenkranz, Francisca; Chamy, Rolando.
Electron. j. biotechnol; 35 (), 2018
Background: Anaerobic digestion is an alternative bioprocess used to treat effluents containing toxic compounds such as phenol and p-cresol. Selection of an adequate sludge as inoculum containing an adapted microbial consortium is a relevant factor to improve the removal of these pollutants. The objectiv...

Phenol degradation and genotypic analysis of dioxygenase genes in bacteria isolated from sediments

Tian, Mengyang; Du, Dongyun; Zhou, Wei; Zeng, Xiaobo; Cheng, Guojun.
Braz. j. microbiol; 48 (2), 2017
Abstract The aerobic degradation of aromatic compounds by bacteria is performed by dioxygenases. To show some characteristic patterns of the dioxygenase genotype and its degradation specificities, twenty-nine gram-negative bacterial cultures were obtained from sediment contaminated with phenolic compound...
