True.
Yes & No. Because there are two types of bacteria Autotrophs , heterotrophs.Autotrophs make their own food with the help of environment & sun energy.Heterotrophs can't make their own food so they eat autotrophs & other heterotrophs.
Usually, natural cheeses have a stank odor and processed cheeses don't smell, which could explain why some cheeses smell and others do not. Many cheese that have strong odors are infused with types of bacteria to develop their flavor and this causes unique aromas.
The bacteria or enzymes in some cheeses create bubbles during the formation of the cheese. We find that these hollow spaces, when sliced, appear as the holes you see.
Bacteria
Viruses and some bacteria aren't useful.
Some cheeses have specific bacterial cultures and mold.
The first cheeses that were made were the type called 'fresh cheese' and looked and tasted like cottage cheese.Many cheeses were (and still are) made by adding special bacteria. An example being the famous Penicillium roqueforti used to make France's Roquefort and England's Stilton cheeses.Cheese makers may encourage the bacterial growth necessary to curdling by a number of odd methods. Some cheeses have bacteria because they are made from unpasteurized milk. Other cheeses, however, are reportedly made from milk in which dung or old leather have been dunked; still others acquire their bacteria from being buried in mud.
bacteria as many useful effects like it is used in the agriculture it is used in medicine to manufacture antibiotic some bacteria are live in alimentary canal to produce enzyme like CELLULASE to digest cellulose in herbivorus
Both, some bacteria is very useful and good for you, like in yogurt. Other bacteria is very harmful and can make you very sick, like staph in staph infections.
Some heterotrophic bacteria are useful for decomposing organic matter, helping with nutrient recycling in ecosystems, and aiding in wastewater treatment processes. Additionally, certain heterotrophic bacteria are used in bioremediation to break down pollutants and contaminants in the environment.
viruses: for treatment of bacterial infection bacteria: for limiting the growth of other bacteria which might hurt our body. fungus,... all the microorganisms can be useful. you should just let them to be.
Cheese is naturally white. They add coloring to make it yellow.
