CECILIANO-CASTRO, Steven et al. Polihidroxialcanoatos (PHAs) en bacterias como alternativa ante el aumento de la contaminación ambiental: análisis metabólico y avances en la actualidad.

Polyhydroxyalkanoates (PHA) are biodegradable plastics synthesized by a wide variety of microorganisms and are identified by sharing very similar characteristics with petrochemical plastics. These biopolymers can be used to replace plastic materials, the same ones that currently represent a major environmental pollution problem as they are poorly degradable. The most recent studies focus on the search for PHA extraction strategies, using bioremediation in petrochemical plastics, fuels, and in water treatment that seek to reduce the impact of environmental pollution. All this is carried out through chemical reactions that bacteria carry out with carbon sources, generating PHA while contaminating waste is eliminated. The main advantage of these compared to petroleum-derived plastics is that being produced by microorganisms. The objective of this review is to show the production of polyhydroxyalkanoates in bacteria as an alternative to the increase in environmental pollution.
