Definitions
- the present invention relates to a lactic acid bacteria culture medium containing whey produced as a by-product of cheese manufacture or casein manufacture. More specifically, the present invention relates to a lactic acid bacteria culture medium characterized by containing whey enriched with a nitrogen source.
- Whey produced as a by-product of cheese manufacture and casein manufacture is a highly nutritious substance containing lactose, water-soluble proteins, minerals, organic acids, water-soluble vitamins, and the like. Wheichi is also used as a concentrated whey powder for whey health foods and beauty products used as confectionery materials and lactose ingredients as whey powder. However, only a part of the whey produced in large quantities is in trouble.
- acidophilus group (6 species of L. acidophilus, L. gassen, L. amyiovorus, L. cnspatus, L. gallinarum, L. johnsonii) derived from human intestine
- acidophilus group 6 species of L. acidophilus, L. gassen, L. amyiovorus, L. cnspatus, L. gallinarum, L. johnsonii
- the acidophilus group generally grows slowly in milk, for example, when it is used for products such as yogurt, it can be grown in a medium other than the product such as yogurt and the bacteria added to the product. It is often done.
- MRS medium for culturing these lactic acid bacteria.
- This medium is very expensive (more than 30,000 yen per kg) and is difficult to use industrially. Therefore, an inexpensive and excellent medium that can replace MRS medium is desired.
- Wheichi is cheap with high nutritional value. In addition, it can be used as a safe food ingredient because it is a component that provides milk power. Therefore, if a lactic acid bacteria culture medium that can be converted into an MRS culture medium can be obtained by effectively using the whey that has been discarded, an inexpensive and industrially available medium can be obtained. Can be obtained.
- whey as a culture medium for microorganisms such as lactic acid bacteria
- examples of the use of whey as a culture medium for microorganisms such as lactic acid bacteria include a culture apparatus for lactic acid bacteria using a medium in which yeast extract is added to whey (Patent Document 1), sweet whey and yeast extract, and casein hydrolysis.
