 note = {The ecologiacl succession of Chlorella saccharophila, Brachionus plicatilis, and autogenous bacteria in
culture water was observed for the purpose of analyzing their microcosms and to determine the
dietary efficiency of bacteria for the culture of B. plicatilis.
B. plicatilis were fed C. saccharophila by using 3 l flasks at the beginning of the experiments. Several
species of bacteria were observed to grow autogenously in the cultured water. Population densities
of C. saccharophila, B. plicatilis, and autogenous bacteria were monitored daily. The behaviour of
autogenous bacteria was closely observed by the introduction of BGA (bacterial growth ability).
BGA was determined by measuring turbidity of population growth of autogenous bacteria which
were sampled from the water and cultured in flasks.
Ecological succession in the flasks were clearly found in each observation. B. plicatilis preferably
consumed C. saccharophila during the first few days. Population density of autogenous bacteria
gradually decreased after C. saccharophila were consumed. Moreover bacterial density increased
again when the population density of B. plicatilis finally decreased.},
