Control of Degradation of Naval Materials Through the Use of Biologically Active Products from the Marine Environment: The Adhesive Properties of 'Chlorella vulgaris'.

Abstract

Ambient sea water contains material that promotes the adhesion of the planktonic algae Chorella vulgaris to plastic surfaces. This adhesion takes place within 3 to 6 hours, and is inhibited by the absence of light. The effect of light on the response of Chlorella to the ocean treated surface is due to the effect of light on the rate of growth of the algal population. The adhesion of Chlorella to glass surfaces is significantly increased in the presence of thymidine and colcemide. Thymidine accelerates the rate of growth of the algal cells and colcemide blocks this growth during mitosis. The effect of ocean deposited materials on the adhesion of Chlorella to plastic appears similar to the effect of agents that increase the relative number of cells to the G2 phase of the cell cycle on the adhesion of this cell to glass.
