“…The environmental impact generated by these toxic substances has led the scientific community to develop different methods for the treatment of industrial effluents contaminated with these substances, which are precipitation, oxidationreduction, exchange ionic, filtration, electrochemical treatment, membrane technologies, and recovery by evaporation. However, these methods have been quite costly and inefficient, especially when the metal concentration is very low, as well as the formation, disposal, and storage of sludge and wastes, originating during the processes, which become a major problem to solve [7].…”

“…Furthermore, the solid on which the adsorption occurs is known as an adsorbent [8], and biosorption is a phenomenon widely studied in the bioremediation of sites impacted by pollution. The study of microorganisms and bioadsorbent material is constantly growing with the use of microbial consortia, which would increase yield's uptake of certain specified metals or mixtures thereof [7,8]. There is evidence of isolation of resistant microorganisms to heavy metals and the use of microbial biomass for the removal of heavy metals from industrial wastewater and/or contaminated water: the isolation and characterization of a variant manganese-resistant strain of Saccharomyces cerevisiae [9]; Pichia guilliermondii resistant to heavy metal [10]; Candida albicans resistant to crude oil [11]; Pichia anomala, Candida krusei, and Cryptococcus laurentii tolerated high concentrations of zinc (up to 20 mM) [12]; the yeast S. cerevisiae partly retains heavy metals (Cu, Fe, Pb, Zn, Ba) and arsenic from soil extracts [2]; hydroxyapatite (HAp)/yeast biomass composites for the removal of Pb +2 [13]; removal of zinc by Pichia kudriavzevii A16 [14]; copper(II) and phenol adsorption by Candida tropicalis [15]; the removal of copper(II) by Candida krusei [16]; the application of bifunctional Mangifera indica L.loaded Saccharomyces cerevisiae as efficacious biosorbent for bivalent cobalt and nickel cations [17]; the biosorption of Cr(VI) from aqueous solutions by Candida albicans and Cryptococcus neoformans isolated from leather works [18]; and Cr(VI) reduction in a chromate-resistant strain of Candida maltosa [19], with highly satisfactory results.…”

“…El análisis químico proximal de la Tabla 1 presenta los principales componentes propiciadores de la remoción de iones metálicos, puesto que en su estructura cuentan con gran presencia grupos OH (hidroxilos y fenólicos); por lo tanto es de esperar que la cáscara de cacao sea un adsorbente con gran capacidad de remoción, ya que su naturaleza lignocelulósica confirma la presencia de compuestos con largas cadenas poliméricas (celulosa, hemicelulosa, pectina y lignina), que son reconocidos por la gran cantidad de grupos hidroxilos y carboxilos que presentan en su disposición [4][5][6], [15], [16]. En el análisis del espectro FTIR de la Fig.…”

“…Los vertimientos de aguas contaminadas con metales pesados a los cuerpos de agua superficiales, provenientes de actividades antrópicas e industriales como metal, textiles, curtiembres, minería, papel, refinerías de petróleo, y manufacturas químicas; representa una amenaza para la salud pública y ambiente, debido a la toxicidad por bioacumulación en los organismos de sales hidrosolubles de iones metáli-cos como el mercurio (Hg), contaminando así las cadenas tróficas, suscitando padecimientos como: ceguera, amnesia, raquitismo, miastenia, cáncer, insuficiencia renal, incluso la muerte [4] [5] [6].…”

“…This is of global concern, as they pose a serious threat to ecosystems by being non-biodegradable, toxic and carcinogenic to humans 1,2,3 Adsorption is a process by which a substance is concentrated on the surface of another solid or liquid phase. It is therefore considered a superficial phenomenon.…”
