Abstract:

The role of marine microorganisms in facilitating attachment, invasions, and subsequent destination, viz., biofouling, of solid substrata, especially wood, in the marine environment was studied. Relationships between microorganisms, primarily bacteria, and invertebrate macroorganisms that bore into wood were also investigated. It was concluded that naphthalene enrichment of creosote retards biofouling of wood pilings during the first year of placement of the treated wood into tropical marine waters. After that, little or no slowing of biofouling can be detected. The wood boring invertebrate, Limnoria, appears to develop a gut microflora that is both naphthalene resistant and capable of naphthalene degradation. It was hypothesized that this gut microflora enabled the wood-boring Limnoria to survive on cresosotenaphthalene-treated wood. Ames assay revealed no detectable mutagenicity in seawater samples collected near creosotenaphthalene-treated pilings.
