STUDIES ON PRODUCTION CONDITIONS OF FLOCCULANT FROM PSEUDOMONAS SP.GX_4-1 USING FISH MEAL WASTEWATER / 微生物学通报

ABSTRACT

The conditions of Pseudomonas sp.GX 4\|1 producing flocculant only using fish meal wastewater were mainly studied.Under the optimum culture conditionsmedium COD 10g/L,initial pH 7～9,cultural temperature 30,and the shaking speed,100～250r/min,the flocculating rates can highly reach more than 97% with maxmium 99 5%,even if the culture medium was not sterilized.This flocculant shows high flocculating efficiency to kaolin clay suspension,soil suspension,activate carbon powder suspension and wastewater fromelectroceramics plant.
