S. Titus et al., EXOPOLYMER PRODUCTION BY A FOULING MARINE BACTERIUM PSEUDOMONAS ALCALIGENES, Indian journal of marine sciences, 24(2), 1995, pp. 45-48
Exopolymeric substances (EPS) secreted by marine bacterium Pseudomonas
alcaligenes grown on basal salt solution medium was analysed for its
biochemical composition. The biopolymer was produced during all phases
of growth and varied with the source and amount of carbon and nitroge
n provided in the growth media. More EPS was produced on active surfac
es like copper than on glass and titanium. EPS which promotes bacteria
l adhesion on immersed surfaces contained carbohydrates (19.8%), prote
ins (16.8%), uronic acids (3.5%), sulphate (0.7%) and pyruvate in trac
es. Inorganic matter was around 52.5%.
