What is Actinobacteria Occurrence and Their Metabolic Characteristics in the Nickel-contaminated Soil Sample about?
Heavy metals are a significant source of pollution in soils that have been demonstrated to exert significant toxic effect on soil microbial assemblages. Here we investigate the occurrence and metabolic characteristics of actinobacteria, which form a predominated component of farmland bacterial community near the town of Sereď in southwest Slovakia, contaminated by close nickel ore facility. Actinobacteria occurred in this environment with high concentrations of nickel (2.109 mg/kg), slightly above the natural occurrence of cobalt (355 mg/kg) and zinc (177 mg/kg), even too low concentration of iron (35.75 mg/kg) for a normal soil and not a toxic amount of copper (32.2 mg/kg) and cadmium (<0.25 mg/kg). The phylogeny was reconstructed using partial sequences of 16S rDNA genes of both, actinobacterial isolates and clones. A total of 105 actinobacterial representatives were divided into 66 species belonging to one order, 7 genera and 5 uncategorized groups. The selected 14 morphologically distinct isolates were able to produce drop collapsing, haemolytic and lipase activities. Whereas only 4 isolates produced dark brown melanin pigment and only 5 of them produced decolourization of the
