Bioremediation Kansa B



S.D. Pekarek, M.K. Banks, K. Rathbone, and A.P. Schwab, 1Civil Engineering and 2Agronomy, Kansas State University, Manhattan, KS 66506 The degradation of petroleum contaminants in soil with the presence of vegetation is being evaluated in a phytoremediation study. The functional diversity of the microbial communities was assessed using the BIOLOG system where utilization of different carbon sources was evaluated for vegetated and unvegetated soil samples. This technique provides a rapid assessment and yields a rich data set to describe the soil microbial community.

The structure of the microbial population appears to vary between soils with different plant species. Significant contrasts were seen between vegetated and unvegetated soil microbial communities probably due to changes in population density. Soil samples with higher contamination dissipation rates demonstrated greater percent degradation of available carbon sources by the microorganisms.

The technique using the BIOLOG system for examining soil microbial communities may demonstrate significant advantages for prediction of phytoremediation success.

Key words: phytoremediation, microbial community, petroleum contamination, soil, degradation
