How CRISPR Technology Changes DNA

Every single cheese that you ingest today on this planet has been produced through some sort of CRISPR technology. It was utilized in cheeses and yogits as a way to improve the process because you need bacteria to make these products, right? But the right limiting step was bacteria fascias were killing off the bacteria as they were making vats of yogurt and cheese. So they use CRisPR technology to just keep introducing new viral fragments to make them immune so that they couldn't die off.
