Abstract
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.
Claims6
A method for separating bacteria cells from a culture broth, which comprises adjusting the pH of said culture broth in the form of a suspension to less than 6 and adding thereto, before or after pH adjustment, a sufficient amount of a solution of casein or alkali-soluble soybean proteins to precipitate the bacteria cells.
