put agar in a Petri dish, then use a Q-tip to wipe a dirty surface, then spread it on the Petri dish in a zigzag motion, then it will grow over time.
When people refer to bacteria growth it is actually about the amount of bacterium in a colony rather than the actual size of an individual bacterium increasing. Bacterium reproduce asexually through binary fission. This is when they basically just make a copy of their chromosome and then split. They reproduce sexually through conjunction. This is when they attach to one another using their pili, which are short hairlike structures on the outside of the cell. Through the pili they transfer a copy of a portion of their DNA. They then take on traits of the other cell. This helps to explain how bacterium can pass on drug resistance to one another.Bacteria is every were and you can get sick if you don't dust daily.
Bacteria need moisture in order to grow. This is why they grow on foods with high moisture content such as chicken. Foods that are dehydrated or freeze-dried can be stored for much longer as the moisture has been removed.

Bacteria (or any cells for that mater) multiply by splitting, they can't split if they're extremely small.
because they have the mycobacteria. a type of organism that makes bacteria grow faster than normal growth.

You don't want them to say little forever do you?
The bacterial growth curve is usually exponential in shape just like most of the living organism.
they need oxygen and heat and moisture to live.
Isopropyl alcohol is used to inhibit bacterial growth because it acts as a disinfectant. This kills the bacteria and prevent them from multiplying.
Yes. Bacterial growth increases with temperature or humidity. Lower temperatures will inhibit or completely stop bacterial growth, but not kill bacteria. The best temperature for fastest growth of some bacterial strains (such as E. coli) is the human body temperature at 37°C. However, most species cannot survive in extreme temperatures. One way to kill common bacterial pathogens using heat is by boiling, a common sterilization technique.

Bacterial hand wash favors the growth of bacteria on the surface of the skin ( hands). On the other hand ( no pun intended) ANTI bacterial hand wash does not favor bacterial growth and in fact contains agents to prevent any bacterial growth on the hands.
The "danger zone" for bacterial growth are temperatures between 5 and 60 degrees
No, drug tests are designed with things such as bacterial growth in mind.
by distorting it
they need oxygen and heat and moisture to live.

There are quite a few liquids that are susceptible to bacterial growth. Water and sugary warm liquids are the most susceptible.
Growth takes place in organisms and not in the Kingdom ,Bacterial replication is called growth .
The best temperature for bacterial growth is around the same temperature as the human body, 98.6 degrees F (37 degrees C).
