A View on the Organic Matter and Metalloporphyrins Biodegradation as Characteristic Components of Black Shale Ores
High content of organic compounds is characteristic for black shale-type ores. Metalloporphyrins are known as the most stable and resistant for biodestruction compounds of organic matter. Based on results obtained in previous studies, four metalloporphyrins were synthesised . The experiments of biodestruction of organic matter extracted from polish black shale ore samples and of the synthetic metalloporphyrins were provided using autochthonous, heterotrophic bacteria mixtures isolated form polish black shale samples, and two Streptomyces species. It was found that biodestruction of black shale organic matter and copper- and vanadylporphyrins is possible, but it is a long term process. Porphyrins of Ni and Fe were resistant to biodegradation.
