Interaction between Illite and a Pseudomonas stutzeri-Heavy Oil Biodegradation Complex.

ABSTRACT: Illite is a widely distributed clay mineral with huge reserves in Earth's crust, but its effect on heavy oil biodegradation is rarely reported. This study made an investigation of the interactions between illite and a Pseudomonas stutzeri-heavy oil complex (PstHO). Results showed that, although illite exerted a negative effect on P. stutzeri degrading heavy oil by inhibiting the biodegradation of 64 saturated hydrocarbons (SHs) and 50 aromatic hydrocarbons (AHs), it selectively stimulated the biodegradation of 45 AHs with a specific structure, and its biogenic kaolinization at room temperature (35 °C) and pressure (1 atm) was observed in PstHO for the first time. The finding points out for the first time that, in PstHO, illite may change the quasi-sequent
