“…Adsorption and enzymatic activity are dependent on the pH [39]. It has been evidenced that the extent of discoloration is influenced by the pH of the media, as well as that the pH affects the color of the solution and the solubility of the dye [40]. For example, Aspergillus fumigatus decolorates 90% of a real textile effluent containing reactive textile dyes including Reactive Black RC, Reactive Yellow HF2-GL, Reactive Blue BGFN, Reactive Black B-150 and Reactive Red A-6BF at values of 3, 78% at pH 5 and 55% at pH 8 [41].…”

The conventional treatments used to remove dyes produced as a result of different industrial activities are not completely effective. At times, some toxic by-products are generated, affecting aquatic ecosystems. In this article, an efficient use of microorganisms is presented as a biodegradation technique that is a safe environmental alternative for the benefit of aquatic life. A strain of the yeast Galactomyces geotrichum KL20A isolated from Kumis (a Colombian natural fermented milk) was used for Methylene Blue (MB) bioremoval. Two parameters of the bioremediation process were studied at three different levels: initial dye concentration and growth temperature. The maximum time of MB exposure to the yeast was 48 h. Finally, a pseudo-first-order model was used to simulate the kinetics of the process. The removal percentages of MB, by action of G. geotrichum KL20A were greater than 70% under the best operating conditions and in addition, the kinetic simulation of the experimental results indicated that the constant rate of the process was 2.2 × 10-2 h−1 with a half time for biotransformation of 31.2 h. The cytotoxicity test based on the hemolytic reaction indicated that by-products obtained after the bioremoval process reached a much lower percentage of hemolysis (22%) compared to the hemolytic activity of the negative control (100%). All of these results suggest that the strain has the capacity to remove significant amounts of MB from wastewater effluents.

“…Heavy metal ions are found in the waste streams of industrial processes [1], such as metal plating, mining activities, smelting, battery manufacture, petroleum refining, alloy manufacture, tanneries, pesticides, printing, and photographic industries [2]. Heavy metal ions have significant ecological impact on ecosystem and can modify the physical and chemical properties of water by affecting the aquatic flora and fauna [3,4], since these pollutions accumulate in living tissues throughout the food chain causing serious health problems [5]. …”

In this study, modified polyvinyl alcohol (PVA) was prepared and characterized by element analysis, scanning electron microscopy, Fourier transform infrared spectroscopy, and surface area and proximity analysis. The isotherms and thermodynamic parameters of the modified PVA adsorption process were estimated. The data indicate that the adsorption process is exothermic, feasible, spontaneous, and fit to the Langmuir isotherm model. The maximum adsorption capacities for Cd(II) and Pb(II) were calculated to be 1.19 and 1.48 mmol/g, respectively. Sorption was rapid, with the removal percentage higher than 98% after 10 min. Adsorption behavior mechanisms were analyzed using pseudo-first-order and pseudo-second-order models, which were highly fitted to pseudosecond-order model. This suggests the main adsorption mechanism is a chemical adsorption, involving ion exchange and valence forces through sharing or exchange of electrons between metal ions and modified PVA. The modified PVA is a good reusable sorbent, enhancing the economics of practical application for the removal of Cd(II) and Pb(II) from water and wastewater.

“…So a substitute approach comprising statistical method, such as response surface methodology (RSM) should be adopted to solve this complexity involved in wastewater treatment [38]. Recently [43][44]. Gönen and Aksu [35] modelled the growth and copper uptake capability of Candida utilis as a function of sucrose and Cu (II) ion concentration in the bioaccumulation medium.…”
