Abstract: During coal combustion soot formation is unwanted. There are many fuel additives used to reduce soot production. In this study toxicity and biodegradation of three types of soot by two soil bacteria strains i.e. Pseudomonas aeruginosa and Bacillus subtilis were compared. Two additives were selected to produce soot samples: (i) commonly used and containing significant quantities of NaCl (40–44%) and copper (Cu-additive), (ii) newly developed without NaCl and with triiron tetraoxide instead of copper (Feadditive). Average number of bacterial co...
