The major requirements for bacterial growth are; Temperature (98.6°F is optimal), Ph Balance (ph7 or close to), Moisture (any amount), Light (Dark places grow more bacteria faster), and a food source.
they eat, grow and didvide. Bacteria will divide every 20 minutes, in a perfect growing environment. This kind of exponential growth has the potential to be very deadly, very quickly, as bacteria kill their host cell within the human body. Luckily, bacteria hit their carrying capacity in the human body at a relatively low manageable level for the immune system to fight off due to competition resulting from such limiting factors as space and food
Bacteria just like other organisms need some nutrient elements like carbon, nitrogen, oxygen , hydrogen, potassium etc. In natural environment they take it from the natural sources but in laboratory condition it is made available to bacteria by growing them in a medium known as cultural medium which contain all these necessary compounds
A growth medium or culture medium is a liquid or gel designed to support the growth of microorganisms or cells, or small plants like the moss Physcomitrella patens. There are different types of media for growing different types of cells.
There are two major types of growth media: those used for cell culture, which use specific cell types derived from plants or animals, and microbiological culture, which are used for growing microorganisms, such as bacteria or yeast. The most common growth media for microorganisms are nutrient broths and agar plates; specialized media are sometimes required for microorganism and cell culture growth. Some organisms, termed fastidious organisms, require specialized environments due to complex nutritional requirements. Viruses, for example, are obligate intracellular parasites and require a growth medium containing living cells
The nutrient media is as:
Nutrient media
This is an undefined medium because the amino acid source contains a variety of compounds with the exact composition being unknown. Nutrient media contain all the elements that most bacteria need for growth and are non-selective, so they are used for the general cultivation and maintenance of bacteria kept in laboratory culture collections.
An undefined medium (also known as a basal or complex medium) is a medium that contains:
Defined media (also known as chemically defined media)
Differential medium
This varies depending on the type of bacteria. For example, warmblooded animal pathogenic bacteria require a temperature of around 98oF, a correct entry site, and for the host to be susceptible to that type of bacteria. Thermo-phillic bacteria require extremely hot temperature to grow. Viruses require a healthy host cell in order to get its DNA/RNA replicated. Parasites require the host body to be healthy enough to sustain itself and the parasite.

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.
A blood culture
The bacterial growth curve is usually exponential in shape just like most of the living organism.
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).
