Characterization and Initial Application of Endophytic Bacillus safensis Strain ZY16 for Improving Phytoremediation of Oil-Contaminated Saline Soils.

ABSTRACT: Hydrocarbon-degrading and plant-growth-promoting bacterial endophytes have proven useful for facilitating the phytoremediation of petroleum-contaminated soils with high salinity. In this study, we identified Bacillus safensis strain ZY16 as an endophytic bacterium that can degrade hydrocarbons, produce biosurfactants, tolerate salt, and promote plant growth. The strain was isolated from the root of Chloris virgata Sw., a halotolerant plant collected from the Yellow River Delta. ZY16 survived in Luria-Bertani (LB) broth with 0-16% (w/v) sodium chloride (NaCl) and grew well in LB broth supplemented with 0-8% NaCl, indicating its high salt tolerance. The endophytic strain ZY16 effectively degraded C₁₂-C₃₂ n-alkanes of diesel oil effectively, as well
