The answer is Lactic acid
The major groups of bacteria that are lactose digest lactose are in a family of bacteria known as coliform. Lactobacillus converts the milk sugars to lactic acid.
It's Bacteria
LACTOSE sugar
Lactobacillus is a type of bacteria that can digest the milk sugar lactose. It produces the enzyme lactase, which breaks down lactose into simpler sugars that can be metabolized. This process is important for the fermentation of dairy products like yogurt.
Lactose is a type of sugar.
Lactose is a type of sugar naturally found in milk, whereas bacteriological grade sugar is a type of sugar that has been carefully processed and sterilized to ensure it is free from any bacteria or contaminants. Bacteriological grade sugar is used in microbiology and other scientific applications where purity is important.
Negative lactose fermentative organisms are bacterial species that do not ferment lactose, a type of sugar. This means they are unable to utilize lactose as a carbon source for energy production. Examples include Salmonella and Shigella species.
Milk contains the sugar lactose.
because lactose is a type of sugar found in milk.
The type of carbohydrate that lactose is a disaccharide. Lactose is the sugar that occurs naturally in cow's and human milk.
Lactose is a specific type of sugar found in milk and dairy products, composed of two simpler sugars: glucose and galactose. While all lactose is sugar, not all sugars are lactose; there are various types of sugars, such as sucrose (table sugar) and fructose (found in fruits). Therefore, lactose is a distinct form of sugar, but it is not synonymous with sugar in general.
When lactose is replaced with another type of sugar like glucose in the MacConkey Agar, it is usually to identify bacteria mutations. The method to detect the fermentation in a replacement sugar solution is the same as lactose fermented solution.
