Biosorption is an effective way to recover or remove metal ions from wastewater; however, the biosorption process in a multiple metal ion solution is still unclear. In this paper, we investigated the simultaneous biosorption in a Pt(IV) and Pd(II) binary system using Providencia vermicola. Kinetics, isotherms, thermodynamics, TEM, and FT-IR were carried out to elucidate the competition behavior and adsorption mechanisms in the process. The results revealed that Pd(II) had a relevant effect on the Pt(IV) biosorption, but the interference of Pt(IV) on the adsorption of Pd(II) was considerably less intense. The maximum adsorption capacity of P. vermicola was 30.20 mg g À1 for Pt(IV) and 119.00 mg g À1 for Pd(II) in the binary system, which corresponded to 3.94 times larger selective adsorption toward Pd(II). The TEM results revealed that P. vermicola could adsorb Pt(IV) and Pd(II) both extracellularly and intracellularly. The FT-IR results indicated that amine groups played major roles in adsorbing Pt(IV), but amine, carboxyl, hydroxyl, and phosphate groups were critical to adsorb Pd(II). This study demonstrates that P. vermicola is a promising biosorbent and could selectively adsorb Pd(II) in the Pt(IV)-Pd(II) binary system.

“…Zinc could be desorbed from Aspergillus flavus using 0.01M HCl with 83.3% elution efficiency and with 23.5% loss in biosorption capacity after five adsorption-desorption cycles [64]. Sodium hydroxide (5M) was able to desorb 81% of Cr 3+ from B. subtilis biomass [51].…”

The present report reviews the potential and applicability of industrial microbe side streams produced in Finnish bioprocess industries for biosorption of heavy metals from wastewaters. Microbial side stream biomasses are formed worldwide in e.g. food, brewing, biofuel, pharmaceuticals, wood processing and enzyme manufacturing industries. Although these streams are typically used for low-valued animal feed or biogas production, they would also have potential for biosorbent materials to be used in in situ water treatment. Since major challenges have been recognized, especially regarding the availability of biomass, and to logistic and processing cost, biosorption is not the most economically attractive option for the use of these biomasses at the moment. However, in the future the situation may change due to new incentives or more cost-efficient biosorbent preparation technologies. This report will provide a knowledge basis for the consideration of biosorption applications for industrial microbe side streams. Journal of Bior emediation & Biodegradation Yeast fermentationsEthanol fermentation process consists of several unit operations to convert carbohydrates into ethanol by S. cerevisiae. This technology is employed worldwide in production of alcoholic beverages and bioethanol. After brewing the yeast cells are collected from the bottom of tank or separated by centrifugation to form slurry of 20-50% solids [6]. Loose slurries are further concentrated by filtration after which they are thermally disrupted at around 80°C and optionally also with organic acids. The production capacity of major Finnish breweries is over 400 million l/a [7] and the respective quantity of formed yeast containing residues is approximately 2000 t/a.Bioethanol is produced by St1 Biofuels Oy in quantity of 13,000 t/a in Lahti, Vantaa, Hamina, Jokioinen and Hämeenlinna. Ethanol is further concentrated at Hamina. These production sites produce altogether over 75,000 t/a of residues that contain also yeast cells. Hämeenlinna plant directs all organic residues to biogas production [8] while the other plants produce also animal feed. The amount of produced feed is over 45,000 t/a [9][10][11][12]. The company has also been appointed an environmental permit in 2013 for production of lignocellulose ethanol in Kajaani [13]. Yeast residues of the process together with other residues would be directed to energy production. Enzyme productionThe main steps in enzyme production processes are medium preparation, inoculum preparation, inoculation and fermentation, cell removal, product purification and concentration, and formulation. The nature of produced enzyme affects also properties of microbial residues. Extracellular enzymes are recovered from the fermentation broth after removal of cells which remains the cells intact. Cell removal is conducted using filter press together with filter aids and flocculants. On the contrary, intracellular products are recovered via disruption of cells by chemical or mechanical methods, after which cell debri...

“…Several authors reported the multi-step behavior of Cr 3+ and Ni 2+ adsorption using various different adsorbents (Oliveira et al, 2005;Nuhoglu and Malkoc, 2009;Chen et al, 2010;Ijagbemi et al, 2010;Karaoğlu et al, 2010;Aravindhan et al, 2012). In this work, Cr 3+ biosorption occurs at the external surface and macro-and micro-pore regions, and Ni 2+ biosorption occurs at the external surface and macropore region.…”

-In this work, the biosorption of Cr 3+ and Ni 2+ by Sargassum filipendula pre-treated with CaCl 2 was studied. Kinetic and equilibrium experiments were carried out for mono-and multi-component solutions in a batch reactor at pH 3.0 and 30 ºC. The results from the kinetic experiments showed that Cr 3+ adsorbs slower than Ni 2+ . This behavior was explained by means of a mechanistic analysis, which showed that Cr 3+ uptake presented three adsorption stages, whereas Ni 2+ adsorption presents only two. The mono-component equilibrium data, along with binary kinetic data obtained from mono-component experiments, showed that, although the kinetics for Cr 3+ removal are slower, the biomass had a stronger affinity for this ion. Almost all Ni 2+ is desorbed from the biomass as Cr 3+ adsorbs. The binary equilibrium data also presented this behavior. The binary data was also modeled by using modified forms of the Langmuir, Jain and Snoeyink, and Langmuir-Freundlich isotherms. However, the prediction obtained presented low accuracy. An alternative modeling with artificial neural networks was presented and the results showed that this technique could be a promising tool to represent binary equilibrium data. The main contribution of this work was to obtain experimental data for Cr 3+ /Ni 2+ adsorption, which is a system rarely found in the literature and that provides information that could be used in process modeling and simulation.
