Description
Summary:This report describes investigations conducted in our laboratory over the past year on the role of microorganisms in marine fouling and boring processes. The microbial succession on wood exposed to the sea was determined using scanning electron microscopy. The sequence in the succession was bacteria, pennate diatoms, cellulolytic bacteria, ciliated protozoa, and stalked protozoa. Macroalgae and invertebrates, including barnacles and wood-boring mollusks and crustaceans, colonized the wood after the microorganisms were established. The possible interaction between marine microorganisms colonized wood exposed in the sea and molluscan wood borers was studied. The presence of a bacterial film on the wood surface but not fungal growth or cellulase treatment increased the density of Lyrodus pedicellatus boring into the wood.
