“…In addition, strain SC2b exhibited a high degree of metal biosorption potential (Figure 3). The capacity of bacterial adsorption of metals is generally dependent upon ionic radius of each metal (Karakagh et al, 2012). Data demonstrated that Zn (0.88 Å) having a smaller ionic radius may be more rapidly complexed by bacteria compared to Cd (0.97 Å) and Pb (1.2 Å).…”

“…and Streptomyces sp., whose MICs were fixed at 3.5, 4.0 and 4.0 mM, respectively. Similarly, Malik and Jaiswal [37] reported that different Pseudomonas strains were unable to tolerate Cd concentrations higher than 1.6 mM. However, Rhodococcus strain 3 showed an unusual ability to resist high concentrations of Cd ( Table 4), suggesting that this microorganism can grow in environments polluted with high concentrations of this heavy metal.…”

The amount of urban sewage sludge is increasing daily. For this reason, it is necessary to have an environmentally friendly use for this residue. Land applications in olive grove soil, poor quality soil, as a compost or a compost tea could be considered as one of the best options, because it has a high content of organic matter. However, the presence of heavy metals in some sewage sludge could be an environmental problem. In this sense, the aim of this work is to check the tolerance of the culturable microbiota present in sewage sludge compost tea to four heavy metals, Cu, Cd, Pb and Zn. Among microbiota isolated, eight strains showed high resistance to Pb, Zn, Cu and Cd, and one microbe (Rhodococcus sp.) showed a special tolerance to every heavy metal. The strains were divided into six genrera: Rhodococcus, Virgibacillus, Leifsoni, Achromobacter, Cupriavidus and Oceanobacillus sp. Finally, Rhodococcus sp. strain 3 was able to remove different amounts of heavy metals from the culture media with intracellular and surface accumulation of Cu, Zn, Pb and Cd. The application of this bacterial strain in bioremediation processes is discussed.

Abstract. The heavy metal resistant isolate FR1 was identified using phenotypic and genotypic characteristics; it was classified as Aspergillus terreus strain. Lactose and yeast extract were favorable for Cr +5 and Cu +2 ions biosorption by tested strain after 6 days incubation period. The positive significant variables (yeast extract, temperature & inoculum size or lactose, yeast extract, temperature & incubation period) affecting heavy metals biosorption using Placket-Burman statistical experimental design in presence Cr +5 and Cu +2 were further optimized by using response surface methodology. It was found that the highest growth of strain in presence of Cr +5 and Cu +2 (4.31 and 3.69 gL -1 ) were attained at 0.15% yeast extract, 2% inoculum size & incubated at 28°C and 0.65 % lactose, 0.15% yeast extract, an incubation temperature of 30 °C and 8 days incubation period, respectively. There is no significant difference between absorption and adsorption mechanism for reduction of heavy metals from Egyptian phosphatic fertilizer sample.
