Abstract: A strain saccharomycete STSM-1 with high flocculanting activity was
isolated from activated sludge with conventional methods. The high production
rate and the low cost STSM-1 medium was obtained by selecting different kinds
of media, carbon source, nitrogen source and inorganic salt ion. The best
flocculant- producing conditions were found by changing medium initial pH,
culture temperature and ventilation flow. The best flocculating effect was
obtained by changing positive ion types, density and concentration of
flocculant.
