THE STRAIN SELECTION OF FLOCCULANT-PRODUCINGMICROORGANISMS USED TO SEPARATE NATURALSODA IN INNER MONGOLIA / 微生物学通报

To solve separating problem of natural soda, fifty-seven strains screened from soil, floul water and activated mud were of flocculating activity. Two strains of bacteria, which were screened from above mentioned strains have higher activity and better steady than the whole culture liquid of bacteria was observed that its flocculating use to natural soda was strong and the mean flocculating rate of two strains were 79.80% and 87.% respectively.
