What condtions are needed for the growth of bacteria?

Answer 1

this totally depends on type of bacteria
temperature, humidity, PH, Oxygen or CO2

Answer 2

It really depends on what kind of bacteria you want to grow. In general you need optimum tempreature, optimum pH, presence or absence of oxygen (depending on type of bacteria), and the right growth medium with the right nutrition depending on what certain bacteria eat.

Most bacteria grow well around 70F or 40C. E. coli grows best at human body tempreature and is classified as a mesophile. Some archaes grow in tempreatures greater than 100C and they're called thermophiles. Psychrophiles grow better below 5C.

There is an optimum pH level depending on the organism. Bacteria tend to do best near neutrality of 6.5-7.5 so usually a buffer is used to maintain a constant pH range, if not, the metabolic processes of the bacteria growing in culture can actually alter pH to undesireable ranges. Acidophiles grow better at lower pH's, and alkaliphiles grow better at higher pH's.

Some bacteria can only grow in the presence of oxygen (obligate aerobes) like Pseudomonas and some are killed by oxygen like Methanococcus (obligate or strict anaerobes), and of course there are ones that grow with or without O2 like E. coli (falcultative anaerobes).

Most bacteria grow well at atmospheric pressure, but some have adapted to love high pressures (barophiles).

Nutrition is aso specific for growing certain types of bacteria. All need the right combination of major elements, trace elements and growth factors.

If you get it all right, the growth curve of bacteria is exponential and is graphed on log paper.

good luck.

Answer 3

it really depends on whar kind of bacteria you have. but for moist baceteria to grow you need a controlled environment that is wet and humid. for the proper growth of most bacterias.

Answer 4

none depending of the bacteria.
