The use of ozone in the effluent treatment of a closed recirculation system for rotifers resulted in a significant improvement of rotifer production and water quality. Compared to a control treatment, the rotifer culture exposed to ozone did not only support a higher rotifer biomass (16000 vs. 8000 rotifers ml -1 ), it also allowed a prolongation of the culture period for 4 days. Compared...
The genetic fingerprint of the microbiota in the culture water of two different rotifer culture systems (batch versus recirculation) was obtained by means of denaturing gradient gel electrophoresis (DGGE) of 16S rRNA gene fragments. The genetic profile of the bacterial community present in the culture water of a batch culture system changed daily due to shifts occurring at the level of the dominance...
