Definition of cisco plural ciscoes : any of various whitefishes (genus Coregonus) that have a large mouth with a long and often projecting lower jaw; especially: lake herring
Milk-based products are rich in both lactic acid and the protein casein. Lactose fermentation to lactic acid increases the food acidity; the acid combines with the casein, and the two coagulate and precipitate.The precipitate is then removed from the milk, and the dairy product derived from it is low in â or free of â lactose.ilk-based products are rich in both lactic acid and the protein casein. Lactose fermentation to lactic acid increases the food acidity; the acid combines with the casein, and the two coagulate and precipitate.
If sucrose or lactose is fermented, the reaction will be A/A (acid slant over acid butt). Because of the high concentration of these sugars, enough acid is produced by fermentation in the butt to lower the pH of both the butt and the slant, turning both yellow.rinciple: TSI contains three sugars â glucose, sucrose, and lactose. Phenol Red is the indicator that turns yellow at an acid pH resulting from fermentation. The glucose concentration is 0.1% and the lactose and sucrose concentrations are 1%.
