Evaluation influence of diesel fuel pollution dose and applied bioremediation interventions on amount of viable organisms biomass in soils
Hawrot, M. | Nowak, A.(Akademia Rolnicza, Szczecin (Poland). Katedra Mikrobiologii i Biotechnologii Srodowiska)
The work presents the results of investigations on microbial activity in soils polluted with two doses of the diesel fuel - soils with different content of organic matter and texture. Additionally, different biodegradation forcing methods were used. Microbial biomass play an important role in estimation of soil activity. It was determined according to SIR method. In soils contaminated with both diesel fuel doses, decrease of the biomass rate was observed during investigations irrespective of content of organic matter or texture except objects inoculed with strain mixture. This was clearly to see especially in light soil, for both used pollution levels (5 and 15 percent). Statistical analysis confirmed highly significant influence of diesel fuel contamination level and applied bioremediation interventions on the microbial biomass in investigated soils
