Notes

Brachionus calyciflorus (Pallas) is a common brachionid in sewage oxidation ponds. The uptake and assimilation of E. coli was optimal at concentrations of 2.7-6.9x10E8 cells ml-1 while assimilation coefficient per body weight of B. calyciflorus was found to be 10% ind.-1 d-1. More than two eggs per individual were produced during 24 hours when brachionids were fed with a mixture of E. coli (10E9 cells ml-1) and Chlorella spp. (10E6 cells ml-1). The nutritional value of the mixture of E. coli and Chlorella spp. was found to be higher than that of bacteria alone.
