Los polihidroxialcanoatos (PHA), son plásticos biodegradables sintetizados por una gran variedad de microorganismos y se identifican por compartir características muy similares con los plásticos de origen petroquímico. Estos biopolímeros pueden ser aprovechados para reemplazar materiales de plástico, los mismos que actualmente representan un gran problema de contaminación ambiental al ser poco degradables. Los estudios más recientes, se enfocan en la búsqueda de estrategias de extracción de PHA, empleando la biorremediación en plásticos petroquímicos, combustibles, y en tratamiento de aguas que buscan reducir el impacto de la contaminación ambiental. Todo esto se lleva a cabo mediante reacciones químicas, que las bacterias realizan con las fuentes de carbono, generando PHA mientras se eliminan los desechos contaminantes. La biodegradabilidad es la principal ventaja de estos materiales sintetizados por medio de microrganismos, en comparación con los plásticos convencionales que no poseen esta propiedad. El objetivo de esta revisión es evidenciar la producción de polihidroxialcanoatos (PHA), en bacterias como alternativa ante el aumento de la contaminación ambiental.

“…Faced with these environmental challenges, researchers have developed numerous effective methods for treating waste solutions . Presently, physical–chemical treatment techniques include adsorption, precipitation/flocculation, reverse osmosis, and ultrafiltration. − Adsorption can effectively remove drug residuals in waste solutions using activated carbon, molecular sieves, and other materials followed by desorption and recovery. − Precipitation/flocculation achieves separation through the addition of flocculants to form insoluble drug ions . Reverse osmosis and ultrafiltration technologies utilize semipermeable membranes to filter out drug residuals and other contaminants.…”

Medicated bath is the most common spiking method used in the development of matrix reference materials for aquatic products; however, the environmental issues caused by the treatment of waste liquid after medicated bath cannot be ignored. We proposed an environmentally friendly spiking method based on microfluidics, which significantly improved the drug utilization rate without the need for subsequent drug residue treatment. Finely processed minced fish samples were fully mixed with quinolone drugs, and minced fish gel microspheres were prepared by microfluidic technology, utilizing the gel's water-locking function to enhance the drug-loading capacity. The results showed that this method can significantly increase the drug-loading capacity of the matrix (2.33−4.03 times) compared with the traditional spiking methods. In addition, the matrix reference material prepared by this method has good stability, and the drug concentration was adjustable and controllable.

“…Various single or multiple units of physical, chemical, and biological processes have been developed to remove contaminants from wastewater, such as precipitation [5,6] , coagulationflocculation, [7,8] flotation, [9,10] membrane filtration, [11,12] ion exchange, [13,14] electrochemistry. [15] Adsorption [16,17] is considered to be one of the most promising technologies in practical application and has been widely employed because of its simple operation, fast kinetics, wide applicability, cost effectiveness and no secondary pollution.…”

Adsorption is an effective technology widely used in the removal of radioactive and other heavy metal ions, the adsorbent plays critical role and development of novel adsorbents is being in urgent demand. In this work, phytic acid (PA)‐modified melamine sponge (MS) adsorbent MS@PDA@PA is prepared conveniently in green solvent water. A wide spectrum of metal ions including radioactive uranyl and transition heavy metal ions can be effectively adsorbed by the MS@PDA@PA due to non‐selectivity of phosphoric acid groups in PA. Different factors including pH of aqueous solution, contact time, and initial concentration of ions on the effect of adsorption of the resultant materials are investigated in detail, and the maximum adsorption capacities for U(VI), Pb(II), Cu(II), Cr(III) are 166.7, 168.5, 114.3, and 101.0 mg g−1 respectively at 298 K. It is notable that the MS@PDA@PA is nonflammable due to employment of MS as frame material, and the thermal stability is even improved after incorporation of PA, greatly reduce the risk of the adsorbent in the processes of storage and usage. The green yet simple synthesis and fire resistance of MS@PDA@PA make it a competitive material for practical treatment of wastewater consisting of toxic metal ions.
