Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

During ecological investigations on the optimum culturing conditions of ciliates, we studied the influence of a number of abiotic factors on the reproductive potential of the hypotrichous ciliate Euplotes vannus Muller, such as the nature and the quantity of food, the temperature and the salinity. The experiments were run in petri dishes of 5 cm diameter containing 5 ml of food suspension, and were always started with conjugants. The microphagous Euplotes vannus thrives on a variety of food media. Excellent results were observed on homogenized bakers yeast, i.e. 10.000-20.000 animals in 5 ml of food suspension. In good culturing conditions the stationary phase was reached in 7 days, which implicates a mean rate of division of 12 hours. The optimum culturing temperature seems to be situated between 20 and 25 °C; although the rate of division was higher at 30 °C (down to six hours) the cultures collapse after a short time and don't reach the high densities mentioned previously. Finally culturing the animals in salinities of 20 promille, 25 promille, 30 promille and 35 promille gave quite similar results, which confirms the euryhaline character of the species as already described by Gause in 1941.
