AB  - Biosorption is evolving as a potential alternative to the existing conventional technologies for the removal and/or recovery of pollutants from aqueous solutions. The present work investigates the possible application of waste biomass Myriophyllum spicatum (Ms) in removing contaminants, evaluating equilibrium through isotherms of selected heavy metals: lead, copper, and cadmium. As a heavy metal biosorbent, Ms was immobilized in alginate beads (Ms: Alginate 2:1). Applied biosorbent, MsA, was characterized by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM–EDX) and Fourier transform infrared spectroscopy (FT-IR). Experimental results were fitted (nonlinear) by six isotherm models: Langmuir, Freundlich, Sips, Redlich and Peterson, Toth, and Temkin. For lead(II) ion removal, fitting follows the following sequence, F ≈ R-P > S > To > L > Te, while for copper(II) and cadmium(II) ions are as follows: R-P > To ≈ Te ≈ L > S > F and R-P > L > To > S > F > Te, respectively. TOC analyses revealed that M. spicatum releases 35.04 mg/L of total organic content while immobilized sample, MsA, only 6.81 mg/L. Finally, this biosorbent was tested on a sample of real wastewater from a coal-fired thermal power plant complex TPP Kostolac (operated by PE “Electric Power Industry of Serbia”). The results indicate that using immobilized aquatic weed M. spicatum as a biosorbent has a high potential for heavy metal wastewater treatment applications.

AB  - The aim of this paper was to investigate whether changes in the quantity and structure of humic acids (HA) occur during bioremediation of waste mazute (heavy residual fuel oil). The effects of humification on the structure of HA were evaluated by Fourier Transform Infrared Spectroscopy (FT-IR), potentiometric titrations, the ratio of absorbances at 465 and 665 nm (E4/E6 ratio) and the ratio. Also, the quality of humification was monitored by determining parameters which are important for measuring the evolution of humic substances (HS), such as CHA/CFA (the humic acidifulvic acidratio), the rate of extraction (TE) and the index of polymerization (IP). An increase of the content of HA from 0.23% to 0.70% was observed during the bioremediation process. The FT-IR spectra and 04 ratio of HA extracted at the beginning and the end of the process indicate structural changes during the bioremediation process. The groups containing aromatic and carboxylic carbon increased, resulting in HA structures of higher aromaticity. An increase of the B4/E6 ratio during bioremediation treatment implied the enrichment of HA with functional oxygen groups. Potentiometric titrations of HA solution showed increases in the buffering and the redox capacities of HA during the bioremediation process. The results of parameters of humification showed an increase of the compositional carbon in HA at the end, compared to at the start, of bioremediation, while the carbon that belonged to fulvic acids (FA) reduced by 44%. Transformation into HA is the likely cause of this observed reduction. The TE and the IP demonstrated that humification occured during the bioremediation process. According to the available data, this is the first report on synthesis of HS during bioremediation of petroleum hydrocarbons. (C) 2017 Published by Elsevier Ltd.

AB  - Iron and sulfur oxidizing chemolithoautotrophic acidophilic bacteria, such as Acidithiobacillus species, hold the dominant role in mine environments characterized by low pH values and high concentrations of reduced sulfur and iron compounds, such as ores, rocks and acid drainage waters from mines. On the other hand, heterotrophic microorganisms, especially their biofilms, from these specific niches are receiving increased attention, but their potential eco-physiological roles have not been fully understood. Biofilms are considered a threat to human health, but biofilms also have beneficial properties as they are deployed in waste recycling and bioremediation systems. We have analyzed interactions of the metal tolerant heterotrophic microorganisms in biofilms with iron oxidizing autotrophic bacteria both from the sulphidic mine environment (copper mine Bor, Serbia). High tolerance to Cu2+, Cd2+ and Cr6+ and the presence of genetic determinants for the respective metal tolerance and biofilm-forming ability was shown for indigenous heterotrophic bacteria that included strains of Staphylococcus and Rhodococcus. Two well characterized bacteria-Pseudomonas aeruginosa PAO1 (known biofilm former) and Cupriavidus metallidurans CH34 (known metal resistant representative) were also included in the study. The interaction and survivability of autotrophic iron oxidizing Acidithiobacillus bacteria and biofilms of heterotrophic bacteria during co-cultivation was revealed. Finally, the effect of heterotrophic biofilms on bioleaching process with indigenous iron oxidizing Acidithiobacillus species was shown not to be inhibitory under in vitro conditions.
