Effect of Corn Plant on Survival and Phenanthrene Degradation Capacity of Pseudomonas Sp. UG14Lr in Two Soils
A study was undertaken to assess if corn (Zea mays L.) can enhance phenanthrene degradation in two soils inoculated with Pseudomonas sp. UG14Lr. Corn increased the number of UG14Lr cells in both soils, especially in the acidic soil. Phenanthrene was degraded to a greater extent in UG14Lr-inoculated...
