STUDY OF MARINE MICROFOULING ORGANISMSSOME CHARACTERISTICS OF THE MICROFOULING TO FIVEMATERIAL SURFACES OBSERVED BY THE SCANINGELECTRON MICROSCOPE

In the last few years, scanning electron microscope (SEM) has been widely used to observeand study community structure and succession of the microfouling organisms on various solid surfaces immersed in the sea^[1-3], polysaccharide components of bacterial slime layer^[4-6], two-tier microfouling layer structure^{[6, 7]}, metal corrosion products in the attached process and character-istics of attached microorganisms on the coating surfaces^{[8, 9]}.The SEM observations indicated that substrate components exposed to natural seawater are one of the important factors affecting microbial adhesion^{[7, 10]}.The present paper examined the influences of several metal materials, from which ship is usually made on microbial adhesion during the exposure to seawater by the SEM and discussed the material selecting problems from the anti-microfouling point of view.
