“…Zhao and colleagues [24] used the Thomas and Dose-Response models to eliminate red by using residual biomass of wheat straw chemically modified with hexadeciltrimethylammonium bromide (CTAB) in continuous system, the Dose-response model was found to better fit the experimental data. Results similar to those found in other research [25,26].…”

In the present investigation, the biosorption process for the removal of Cadmium in synthetic waters was adjusted on a pilot scale using cocoa shells as a biosorbent. This was obtained by calculating the experimental values using the response surface methodology (RSM) and an experimental design 3 3 , varying the feed rate, initial solution concentration and bed height, where the respective rupture curve was determined, using the Adams-Bohart, Thomas, Yoon-Nelson and Dose Response models to describe the behaviour of the column and obtain the kinetic parameters. The model that best fitted the experimental data and described the rupture curve was the Dose-response model, with an R 2 value of 0.9979, followed by the Yoon-Nelson model with an R 2 value of 0.9503, the Adams-Bohart model with an R 2 value of 0.9246, and finally the Thomas model with an R 2 value of 0.8728, which reached 0.9246. The cocoa shell is shown as a good precursor to generate adsorbent at low cost of heavy metals.

“…3S1. This gram‐negative bacterium has an extraordinary facility to form biofilms, which adds value in the field of industrial biotechnology, since this allows its use in the design of biofilters . It also has other advantages, since despite belonging to a genre of known prokaryotic pathogens, it is a ubiquitous microorganism and nonhemolytic as demonstrated by tests on blood agar, therefore its use at industrial level should not be a problem, much less when, as explained below, the huge amount of functional groups present in its cell wall make it a good candidate for use in idle mode.…”

BACKGROUND In this work, the ability of biosorption and bioaccumulation of Zn (II) ions by Klebsiella sp. 3S1 has been investigated. This bacterium had already demonstrated its ability to remove Pb and Ag ions by different mechanisms. The mechanisms involved in the process have been studied using four techniques: FTIR, SEM–EDX, TEM‐EDX and confocal microscopy. Kinetic and equilibrium studies have also been performed. RESULTS The main operating variables were optimized by a Rotatable Central Composite Design (RCCD) that yielded the following values: 0.36 g L‐1 biomass, pH 5.20 and 34 °C temperature, although the equilibrium data were obtained at a temperature of 25 °C, more in line with the environmental conditions. The model that best fitted the experimental kinetic data turned out to be the pseudo‐first‐order one. Maximum capacity of biosorption under the Langmuir model was 48.4 mg g‐1. Finally, the presence of two general mechanisms in the biosorption process was confirmed: cytoplasmic bioaccumulation and complex surface adsorption. CONCLUSIONS Klebsiella sp. 3S1 can be an effective and inexpensive microorganism to remove heavy metals from contaminated effluents, which along with its ubiquity and great ability to form biofilms, make it a promising biosorbent for use in biofilters. © 2017 Society of Chemical Industry

“…Moreover, the literature reports the isolation of a native strain identified as Klebsiella sp. 3S1 biofilm isolated from a wastewater treatment plant in the old mining district Linares-La Carolina located in Sierra Morena (España) [21]. Although the front face of the colony does not show sulci when seen from above, it presents well marked rugosities.…”

La contaminación por metales pesados es actualmente uno de los problemas ambientales más serios y complejos de tratar. Las pilas de lixiviación de las industrias mineras se caracterizan por su elevado contenido en metales disueltos, además de ser considerado un hábitat propicio para el desarrollo de microorganismos resistentes. Entre ellos, aquellos microorganismos autóctonos con adaptaciones fisiológicas que le permiten tolerar elevadas concentraciones de metales pesados los cuales son considerados como candidatos para procesos de biorremediación. Por esto, el objetivo de este estudio fue aislar y seleccionar cepas de hongos filamentosos con potencialidad para la remoción de metales pesados. Se tomaron muestras de pilas de lixiviación de la Mina Hualilán en la provincia de San Juan (Argentina). El aislamiento de los hongos filamentosos se llevó a cabo en medio Sabouraud-glucosa-agar con antibióticos y se identificaron por técnicas de biología molecular (amplificación y secuenciación del fragmento ADNr 18S y 26S, ITS1, ADNr 5.8S e ITS2). Se estudió la tolerancia a Cu (II) y Pb (II) en placas con medio PDA con concentraciones entre 25 y 800 ppm de cada metal. Las condiciones de incubación fueron a 28ºC durante un período de total desarrollo de los hongos comparado con una placa control (sin metal), midiendo diámetros de crecimiento. Se realizó un análisis estadístico haciendo un análisis de varianza y prueba de comparación de promedios Duncan, con el programa estadístico Anova multifactorial bajo un diseño experimental completamente al azar con arreglo factorial 2x6x1, una caja Petri como unidad experimental, y tres repeticiones. Como resultado se aislaron tres cepas: Penicillium simplicissimum, Fusarium sp y Penicillium funiculosum. Los hongos identificados presentan tolerancias a distintas concentraciones de soluciones de los metales, donde la cepa más tolerante fue Penicillium simplicissimum.
