|Laboratory examination of the growth dynamics of the green alga Selenastrum capricornutum in a turbulent flow|
|The kinetics of freshwater algal growth with hydrodynamic mixing conditions are important in predicting/detecting algal blooms. One of the relevant features concerning green algae is the consistent inhibitory effect of small scale fluid motion on cell division. The degree to which the physical environment at these scales impact on organisms remains controversial.
This study investigates the growth dynamics of the green algae Selenastrum capricornutum in a well defined flow system. The growth rates of S. capricornutum are measured in a range of fluid flow conditions and the effects of turbulence are investigated. The determination of aggregate formation resuting from turbulent conditions is achieved via an image processing unit. The influence of turbulent verses stagnant conditions on the growth rate of S. carpricornutum provides interesting findings into the impact of turbulence on the cell division of S. capricornutum.|
