Screening of possibilities of deep subsurface microflora to decompose selected organic compounds Abstract The aim of the study is to test the deep microflora bacterial strains for their ability to grow in oily environment, aliphatic hydrocarbons and toluene were taken as examples of aromatic hydrocarbons and where the cultivation of selected strain, were produced for testing its growth and microbial activity of selected strains in conditions simulating soil conditions; assess the usability these strains in practical remediation of contamination by oil. This thesis deals with the evaluation of possible use of selected strains of deep microflora for oil decomposition. It is evident, that some groups of microorganisms living in the Tertiary claystones at depths of 30-450 m below the surface are the biodegradable fossil organic matter type of kerogen. Chemical findings indicate that, this organic matter consists of various lengths of aliphatic chains, and thus the assumption that microorganisms decomposing kerogen might be able to disassemble oil and petroleum products. The findings of our experiment indicate that benzene and toluene, as well as kerogen are highly resistant to organic compounds and evidence of microbial degradation are rare. Utilization of oil as representative aliphatic compounds is better...
