Immobilization of bacteria on polymer matrices for degradation of crude oil and oil products

Organic polymer materials (OPM) differing in sets of functional groups, fiber surface thickness and character, and density of fiber packing in fabric were synthesized. OPM were studied for assessing the possibility of their application as sorbents for oil spills in water bodies. The synthesized OPM were used for the creation of bio-hybrid materials as matrices for immobilization of bacteria of the genus Rhodococcus sp. capable of petroleum degradation. Actively dividing bacterial cells forming clusters were shown to be present at the surface of fibers. Active attachment of the cells to polymeric surface due to intrusion and/or excretion of extracellular biopolymeric matrix were detected. The modification of polymer sorbents was shown to influence bacterial immobilization. The peculiarity of growth and the specificity of cell morphology of bacterial culture were noted.
