Lactobacillus helveticus: importance in food and health
Lactobacillus helveticus belongs to a group of organisms collectively known as lactic acid bacteria (LAB). This organism has a Generally Recognized as Safe (GRAS) status and displays a number of features that make it particularly suitable for dairy applications. Lactobacillus helveticus is traditionally used in the manufacture of Swiss-type cheeses and long-ripened Italian cheeses such as Emmen...
متن کاملLactobacillus helveticus: the proteolytic system
Lactobacillus helveticus is one of the species of lactic acid bacteria (LAB) most commonly used in the production of fermented milk beverages and some types of hard cheese. The versatile nature of this bacterium is based on its highly efficient proteolytic system consisting of cell-envelope proteinases (CEPs), transport system and intracellular peptidases. Besides use of L. helveticus in cheese...
متن کاملEffects of milk fermented by Lactobacillus helveticus R389 on immune cells associated to mammary glands in normal and a breast cancer model.
Antitumour activity is an effect attributed to probiotics and fermented foods. Here, the immune cells in mammary glands and cytokine concentration in serum were analyzed using mice fed with milk fermented by Lactobacillus helveticus R389 or L89 (proteolytic-deficient variant), injected or not with breast tumour cells. Mice were fed 7 days with fermented milk, injected with breast tumour cells a...
متن کاملOral intake of Lactobacillus helveticus-fermented milk whey decreased transepidermal water loss and prevented the onset of sodium dodecylsulfate-induced dermatitis in mice.
We investigated the effects of oral intake of Lactobacillus helveticus-fermented milk whey on the intact and sodium dodecylsulfate (SDS)-exposed skin of Hos:HR-1 hairless mice. The mice were allowed to drink 10% L. helveticus-fermented milk whey in distilled water ad libitum for 5 weeks. SDS solution was topically applied to the dorsal skin at 4 weeks, leading to the development of dermatitis. ...
متن کاملprtH2, not prtH, is the ubiquitous cell wall proteinase gene in Lactobacillus helveticus.
Lactobacillus helveticus strains possess an efficient proteolytic system that releases peptides which are essential for lactobacillus growth in various fermented dairy products and also affect textural properties or biological activities. Cell envelope proteinases (CEPs) are bacterial enzymes that hydrolyze milk proteins. In the case of L. helveticus, two CEPs with low percentages of amino acid...
