yogurt, yeast, mold
Well with the correct bacteria you can get cheese,yoghurt,,,
Yes. Enterobacter aerogenes ferments lactose and glucose as well as producing gas. It does not produce H2S. Occasionally the slant may revert to an alkaline reaction even though lactose has been fermented. Another lactose test should be formed, such as the reaction on MacConkey agar
Formation of curd in milk is called 'Fermentation'.Curd is formed when milk is pasteurised and fermented by a combination of lactic acid bacteria and a protease.
Lactose is not a macromolecule. It is a disaccharide, that is one molecule of lactose is formed by the elimination of water between two simple sugar molecules, in this case galactose and glucose. Lactose can be made to link up into medium chain molecules, but this is a fairly random process and produces a mixture of products which are not digestible.

Reaction products are formed.
You could determine whether a bacterium fermented the carbohydrates, mannitol, sorbitol, adonitol, or arbinose by a color change. Also gases are formed.

Monsaccharides are a simple for a sugar and can have a sweet taste. They are usually colorless and water-soluble. Monosaccharide includes glucose and galactose. Lactose is made from both of those at its simplest forms.
