“…Biodegradation has been described as a major removal mechanism that is capable of affecting the fate of EDC in the environment (Yu, Deeb, & Chu, ). Over the years, several studies have reported the degradation of various EDC by different microorganisms (Ahuactzin‐Perez et al., ; Cajthaml, ; Combalbert & Hernandez‐Raquet, ; Husain & Qayyum, ; Yu et al., ; Zhang et al., ; Zhao et al., ). Ligninolytic organisms, predominantly, white rot fungi (WRF), have received increased attention for degradation of various emerging micropollutants.…”

Direct municipal wastewater effluent discharge from treatment plants has been identified as the major source of endocrine‐disrupting chemicals (EDC) in freshwaters. Consequently, efficient elimination of EDC in wastewater is significant to good water quality. However, conventional wastewater treatment approaches have been deficient in the complete removal of these contaminants. Hence, the exploration of new and more efficient methods for elimination of EDC in wastewater is imperative. Enzymatic treatment approach has been suggested as a suitable option. Nonetheless, ligninolytic enzymes seem to be the most promising group of enzymes for EDC elimination, perhaps, owing to their unique catalytic properties and characteristic high redox potentials for oxidation of a wide spectrum of organic compounds. Therefore, this paper discusses the potential of some ligninolytic enzymes (laccase, manganese peroxidase, and versatile peroxidase) in the elimination of EDC in wastewater and proposes a new scheme of wastewater treatment process for EDC removal.

“…Chiu et al (1998) and Sadiq et al (2019) reported that the spent mushroom compost of P. pulmonarius and P. ostreatus was able to degrade toxic organic pollutants such as pentachlorophenol and endosulfan, pesticides reported to be carcinogenic. Ahuactzin-Pérez et al (2018) found that P. ostreatus degrades and uses as carbon and energy source high concentration (1000 mg/L) of di(2-ethyl hexyl) phthalate, which is a plasticizer that interfere with endocrine systems in mammals and has been detected as contaminant in the environment. The potential for using Pleurotus for pollutant and plastic degradation is discussed by Sánchez et al (2020).…”

We review the most recent developments in understanding the nature of development and morphogenesis in fungi and suggest how it might be applied to biotechnological manipulation of some cultivated mushrooms. We believe that it is essential to match the deductions of the molecular observations of the genomics generation with the inductive reasoning of the in vivo experiments and observations of the pregenomics generations to take full advantage of the synergism between the approaches to illuminate better the living biology of the system. As specific examples we show how model mushroom fungi (Coprinopsis and Volvariella) make hymenia and gills (not forgetting how the polypore Phellinus makes tubes), developmental commitment and pattern formation. The Coprinopsis sporophore also provides examples for the construction of mushroom stems and the coordination of cell behaviour throughout the maturing sporophore and the timing process that achieves that. This leads us to consider the mechanics of the mushroom and its dependence on the biochemistry and regulation of metabolism in relation to morphogenesis, and how it varies between species. We finish with our summary of the basic principles of fungal developmental biology. Having demonstrated how classic approaches allowed progress to be made in the study of fungal development we show how this has been accelerated by genomics and other aspects of global analysis of macromolecules. We also include work on some cultivated mushrooms to illustrate how the generalisations from research on model organisms might be applied in mushroom farming.

“…En los medios adicionados con DBF, la glucosa fue consumida en su totalidad después de las 40 h y a la mitad de la fase exponencial lo que sugiere que N. sitophila empleo el DBF como fuente de carbono hasta alcanzar la fase estacionaria. El uso del ftalato como fuente de carbono depende del microorganismo utilizado y de la complejidad de la estructura del ftalato (Ahuactzin-Pérez et al, 2018). Se ha reportado que los ftalatos con cadenas de éster más cortas como DBF pueden ser más fáciles de biodegradar y mineralizar que los ftalatos con cadenas de éster largas como DEHF (Liang et al, 2008).…”

“…La disminución del pH en los medios conteniendo DBF fue durante las primeras 40 h de fermentación alcanzando un mínimo de pH de 5.75 y 5.5 para 1500 y 2000 mg de DBF/L, respectivamente, lo que sugiere la presencia de compuestos ácidos, debido a la degradación del sustrato. Lee et al (2004) encontraron una tendencia similar a la reportada por Ahuactzin-Pérez et al (2018) en cambios del pH en estudios realizados con hongos de pudrición blanca. Esto se debe a la producción de ácido o-fenilacético, ácido o-anísico y diferentes ácidos grasos durante la biodegradación de los ftalatos (Staples et al, 1997).…”

“…Se ha reportado que las enzimas esterasas con capaces de hidrolizar enlaces éster y que los productos de degradación obtenidos no son tóxicos (Kim et al, 2002, Ahuactzin-Pérez et al, 2014. Algunas especies de hongos como Fusarium oxysporum (Kim et al, 2003), Fusarium culmorum (Ahuactzin-Pérez et al, 2016), Pleurotus ostreatus (Ahuactzin-Pérez et al, 2018), Trichoderma harzianum (Aguilar-Alvarado et al, 2015) entre otros, han sido reportados como organismos capaces de degradar ftalatos. Por lo tanto, es importante encontrar organismos con la capacidad de producir esterasas que puedan ser empleados para la degradación de los ftalatos, a través de la ruptura de los enlaces éster presentes en estos compuestos.…”

Los ésteres de ftalato son compuestos usados principalmente como plastificantes y aditivos para proveer de flexibilidad y maleabilidad a los productos plásticos. Dentro de los ftalatos más empleados se encuentra el dibutil ftalato (DBF), el cual se utiliza como un aditivo en adhesivos, tintas para impresoras y en productos cosméticos. En este trabajo se evaluaron la velocidad específica de crecimiento (μ), biomasa máxima (Xmax), pH, consumo de glucosa y actividad específica de esterasas de Neurospora sitophila en medios adicionados con diferentes concentraciones de DBF (1500 y 2000 mg/L) en fermentación sumergida. N. sitophila presentó una mayor velocidad específica de crecimiento en el medio adicionado con 1500 mg de DBF/L que en el medio adicionado con 2000 mg de DBF/L. El medio adicionado con 2000 mg de DBF/L presentó la mayor producción de biomasa. La mayor actividad específica de esterasas fue observada en el medio conteniendo 1500 mg de DBF/L. Esta investigación sugiere que N. sitophila es capaz de emplear altas concentraciones de DBF como fuente de carbono y energía.
