Dynamics of extracellular polymeric substance (EPS) production and loss in an estuarine, diatom-dominated, microalgal biofilm over a tidal emersion–immersion period
extracellular polymeric substance diatom-dominated
2014/4/23
We studied patterns of production and loss of four different extracellular polymeric substance (EPS) fractions—
colloidal carbohydrates, colloidal EPS (cEPS), hot water (HW)–extracted and hot bicarbo...
