AB - The first traces of Tetracycline (TE) were detected in human skeletons from Sudan and
Egypt, finding that it may be related to the diet of the time, the use of some dyes, and the use of
soils loaded with microorganisms, such as Streptomyces spp., among other microorganisms capable
of producing antibiotics. However, most people only recognise authors dating between 1904 and
1940, such as Ehrlich, Domagk, and Fleming. Antibiotics are the therapeutic option for countless
infections treatment; unfortunately, they are the second most common group of drugs in wastewaters
worldwide due to failures in industrial waste treatments (pharmaceutics, hospitals, senior residences)
and their irrational use in humans and animals. The main antibiotics problem lies in delivered and
non-prescribed human use, use in livestock as growth promoters, and crop cultivation as biocides
(regulated activities that have not complied in some places). This practice has led to the toxicity of
the environment as antibiotics generate eutrophication, water pollution, nutrient imbalance, and
press antibiotic resistance. In addition, the removal of antibiotics is not a required process in global
wastewater treatment standards. This review aims to raise awareness of the negative impact of
antibiotics as residues and physical, chemical, and biological treatments for their degradation. We
discuss the high cost of physical and chemical treatments, the risk of using chemicals that worsen
the situation, and the fact that each antibiotic class can be transformed differently with each of these
treatments and generate new compounds that could be more toxic than the original ones; also, we
discuss the use of enzymes for antibiotic degradation, with emphasis on laccases.
