Chromatographs of solvent extracts from microcosms containing POPILE
soil after 11 months. Panel A: untreated soil. Panel B: soil amended with bulking
agent (ground rice hulls) and dried-blood fertilizer. Panel C: soil amended with
bulking agent, dried-blood fertilizer, and
P. aeruginosa
strain 64 on the vermiculite
carrier.

agent (used in 1:1 volume of soil to bulking agent) diluted the contaminants
compared to the controls (no treatment). Therefore, we measured the PAHs
