Effect of temperature on the rate of concentration of faecal coliforms in mussels

The effects of different temperatures (12oC, 18 oC, 24 oC) on the rate of concentration of faecal coliforms (FC) in mussels were studied in experimental conditions at different concentrations of FC in seawater. At low initial concentrations of FC in mussels the rate of FC concentration increased with concentration of FC in seawater and with increase of temperature. As concentration of FC in mussels increased, the rates of FC concentration decreased more rapidly at higher concentration of FC in seawater and at higher temperature. As the FC concentration in mussels kept on growing the rate of concentration became inversely proportional with temperature. As a consequence of that, the lower temperature, the higher was the level-off concentration (which is the maximal concentration of FC present in mussels), and mussels needed more time to reach the level-off concentration.
