Method for separation of bacteria cells from culture broth

摘要

Bacterial cells are separated from a culture broth by adding thereto a solution of casein or alkali-soluble soybean proteins, said culture broth being maintained at a pH less than 6. Bacteria cells are flocculated to form a protein-bacteria co-precipitate which is easily separable by a conventional procedure. The co-precipitate may be directly put to uses such as for foods or feeds.
