Bacterias beneficiosas

La composición de las bacterias de yogurt están sufriendo una importante modificación debido a las influencias de los países asiáticos.
“Standard yogurt is typically made by a combination of Streptococcus salivarius thermophilus and Lactobacillus delbrueckii bulgaricus,” dice Joseph H. Hotchkiss, profesor y director del Departamento de Ciencia de os Alimentos de la Cornell University. “In recent years in other parts of the world, there has been increasing use of Bifidobacterium longum, long established in Japan, which has also caught on in Europe, especially in drinkable yogurt.”
Puedes fabricar tu propio yogurt en casa ya que las especies beneficiosas que producen el yourgurt fermentando la leche han sido identificadas. Hace bastante tiempo, la mala esterilización hacía que las mismas cubas donde de hacía en yogurt conservaban las cepas bacterianas responsables de la fermentación. Como dice Hotchkiss, “You can buy home yogurt appliances, which are basically little warm incubators, with packets of dried culture, and make more yogurt.”
De hecho nos podemos convertir en pequeños biotecnólogos fabricando nuestro propio yougurt en casa. Las bacerias son nuestras aliadas ya que “If you counted the individual cells in a human being, 90 percent would be bacteria, chiefly in the gut. There is a symbiotic relationship with bacteria, and yogurt helps maintain it.”
