INTERNATIONAL SYMPOSIUM ON INFORMATION TECHNOLOGY IN OCEANOGRAPHY (ITO-98) GOA, INDIA 12-16 OCTOBER 1998

A multitude of man-made objects placed in the sea eventually acquire attached communities of marine organisms. This is due to intricate composition and molecular structure. Physical and chemical nature of the primary adsorption films on the surfaces. The microbial activity conditions the surfaces for macroscopic biological fouling. Dexter et al.. 1976 ) reported that bacteria are found attached to surfaces within few hours of immersion in the sea. Sorbed films produced interferes with a range of wettabilities dependant upon substratum and sorbate properties( Taylor et al..1997 ). Microbially produced polysaccharides and glyco-proteins are present in the seawater in dissolved form and adsorbed to detrital particles and submerged surfaces. The adhesive extracellular polysaccharide has been identified with scanning electron microscope ( Fletcher and Floodqate.1973; Marshall et al 1971a; Gerchaker et al 1977).

A combination of novel and sensitive techniques has been used to examine the initial phases of chemical and bacteriological attachment to solid surfaces under simulated in-situ conditions. Several models of microbial surface colonisation have been advised to quantitate growth and attachment rates on the surfaces. Caldwell et a] (1983) used a computer simulation of surface microcolony formation during microbial colonisation. Biolog has developed a directed systematic process foe selecting sets of substrates that can be used to identify and characterise unknown microbes with a high degree of accuracy ( Bochner. 1989 ). Data of this type are also being used by the U.S.Department of Energy's Deep Surface Microbiology Programme to characterise the degradative capabilities for pollution clean up. New types of information tools like microcomputers present an ideal opportunity for modelling. Data collection, Data processing and data document processing. An attempt is being made to project surface properties of microbes with the help of DBMS that can handle the data efficiently and economically. This should be considered to be alternate approach of information systems to the conventional methods.
