Seasonal Progress of Biofilm-Forming Bacteria on Acrylic Surface in Seawater

Abstract

Usual marine environments contain only dilute substances which can be used for metabolism and growth, and interfacial effect of natural surfaces tends to collect and concentrate nutrients by charge-charge or hydrophobic interactions. Surfaces contact with water rapidly colonized by bacteria. In this study we analyze the bacterial number, extracellular enzyme activities, metabolic changes and the changes of community composition of biofilm on acrylic surface in seawater during initial period and after maturation.
