Those which show pink colour in gram staining are gram negative bacteria
like E.coli
Microbes is a more global term for small living creatures. Some have negative impact on our system when they intrude our body, called pathogens. They interfere with reactions in our body.
Bacillus cereus is a spore-forming microbe that is gram-positive, not gram-negative. Gram-negative spore-forming microbes include Clostridium botulinum and Clostridium tetani.
There are good microbes in your intestines that help you digest food. There are also good microbes in the soil that break down dead plants and other waste, producing nutrients for the next generation of plants. Bad microbes would be the ones that make you sick, such as an infected cut, pneumonia, tuberculosis, etc.
If you do open one or more of them, you can contaminate them with microbes. These will most likely not be the ones you are trying to culture. It can give you a false negative.
Microbes play a crucial role in maintaining our ecosystems and are essential for food production and waste decomposition. However, some microbes can cause disease and infections in humans, plants, and animals. Proper hygiene and sanitation, along with understanding how to harness beneficial microbes, can help us better utilize the good aspects while minimizing the negative impacts of microbes.
If you do open one or more of them, you can contaminate them with microbes. These will most likely not be the ones you are trying to culture. It can give you a false negative.
Alexander flaming discovered microbes
microbes can live anywhere!
sometimes Bactria can kill microbes
Fermentation process microbes.
Microbes live best in grass because of cellulose in the grass. But microbes can live anywhere.
Virus do not have cells.Other microbes have cells.
