Yes
bacteria is not harmless if there is alot of bacteria then you can get really sick.
Spoilage can be from bacteria, but it can also be caused by yeasts and molds - which are not bacteria.
Yogurt and buttermilk are fermented by a harmless bacteria added after pasteurization to prolong their shelf lives.
The harmless living bacteria took in pneumonia-causing DNA(genes) from the heat-killed, pneumonia-causing bacteria, as a result of which the harmless bacteria changed into bacteria that cause pneumonia.
smooth
i know that 1 way is pasteurisation
Refrigeration will slow down the growth of bacteria in the milk, but not kill the bacteria. This will slow down spoilage.
The purpose of pasteurization is to prevent spoilage by killing all microorganisms, especially bacteria.
The main way that pasteurization methods prevent food spoilage is by removing the bacteria from the food. This is done by heating the food until it is hot enough to kill the bacteria and then holding it there long enough to make sure that all bacteria are killed.
The lactic acid is generally produced by members of the genus lactobacillus. These bacteria are generally harmless to humans. The acidic environment they create, however, harms other bacteria and prevents these potentially dangerous bacteria from growing. So, overall, the food that's being preserved will have predominantly only one type of bacteria in it, which is not harmful to humans.
Yes, but most are weak and almost harmless.
