Cone cells, or cones, are one of two types of photoreceptor cells in the retina of the eye. They are responsible for color vision and function best in relatively bright light, as opposed to rod cells, which work better in dim light.
The two most common types of fermentation are (1) alcoholic fermentation and (2) lactic acid fermentation. (1) Alcoholic fermentation: the type of fermentation in which ethyl alcohol is the main end product .This is very common in yeast (unicellular fungus) and also seen in some bacteria.ermentation is of different types and takes place under anaerobic conditions mostly in saprophytic microorganisms like certain bacteria and fungi. However, it may also take place in higher organisms under certain conditions.
The main fermentation products include organic acids, ethyl alcohol and carbon dioxide. Commercially the mostly important are lactic acid and ethanolic fermentations. Lactic acid fermentation is used in fermentation of milk, vegetables (cucumber, cabbage, cassava), cereals (wheat, maize), meat and fish.In milk and meat fermentations, starters are necessary, in other â natural flora is sufficient.Alcoholic fermentation is one of the most important and the oldest processes.actic acid fermentation is used in fermentation of milk, vegetables (cucumber, cabbage, cassava), cereals (wheat, maize), meat and fish.
