ABSTRACT

The biotechnological methods have wide application area in the remediation of heavy metals from the waste waters. This study presents the results of the biological-chemical activation of coal waste from the Cigel deposit (Slovakia) by selected species of microorganisms, as well as: Aspergillus niger, Aspergillus clavatus, Penicillium glabrum and Trichoderma viride. The quantitative maceral composition has been investigated. The complex maceral analysis shoved that microorganisms preferentially disrupt the structure of humotelinite and liptinite in a variety of degrees. After were
studied activated samples with the aim to enhance its sorption properties.

Keywords: brown coal, microorganisms, maceral composition changes, adsorption
