abstract = {Polyphenols and their intermediate metabolites are natural compounds that are spread
worldwide. Polyphenols are antioxidant agents beneficial for human health, but exposure to some of
these compounds can be harmful to humans and the environment. A number of industries produce
and discharge polyphenols in water effluents. These emissions pose serious environmental issues,
causing the pollution of surface or groundwater (which are used to provide drinking water) or
harming wildlife in the receiving ecosystems. The treatment of high-polyphenol-content waters is
mandatory for many industries. Nowadays, biotechnological approaches are gaining relevance for
their low footprint, high efficiency, low cost, and versatility in pollutant removal. Biotreatments
exploit the diversity of microbial metabolisms in relation to the different characteristics of the
polluted water, modifying the design and the operational conditions of the technologies. Microbial
metabolic features have been used for full or partial polyphenol degradation since several decades ago.
Nowadays, the comprehensive use of biotreatments combined with physical-chemical treatments
has enhanced the removal rates to provide safe and high-quality effluents. In this review, the
evolution of the biotechnological processes for treating high-polyphenol-content water is described.
A particular emphasis is given to providing a general concept, indicating which bioprocess might be
adopted considering the water composition and the economic/environmental requirements. The
use of effective technologies for environmental phenol removal could help in reducing/avoiding the
detrimental effects of these chemicals. In addition, some of them could be employed for the recovery
of beneficial ones.},
