1_A spectrophotometer is used to determine turbidity by measuring
the amount of light that passes through a suspension of cells.
2_An indirect way of estimating bacterial numbers is measuring the
metabolic activity of the population (for example, acid production
or oxygen consumption).
3_For filamentous organisms such as fungi, measuring dry weight is
a convenient method of growth measurement.

How long do petri dishes need to be put in an incubator for to promote microorganism growth?
Petri dishes are typically left in an incubator for 24-48 hours to promote microorganism growth. The exact time may vary depending on the type of microorganism being cultured and the optimal growth conditions required. It's important to follow specific protocols for each type of microorganism.
Is carbon dioxide or the growth of microorganism a characteristic of life?
Carbon dioxide is NOT a life characteristic.
What is Bait technique in isolation of culture media?
In the context of isolation of culture media, the bait technique involves using a specific substance or material to attract and isolate a target microorganism. This substance serves as a bait to selectively encourage the growth of the desired microorganism while inhibiting the growth of others present in the environment. By utilizing this technique, researchers can effectively isolate and identify the target microorganism from a mixed microbial population.
What is agar dilution test?
The agar dilution test is a method used in microbiology to determine the minimum inhibitory concentration (MIC) of an antimicrobial agent against a particular microorganism. It involves placing different concentrations of the antimicrobial agent on agar plates inoculated with the microorganism and observing which concentration effectively inhibits its growth. The MIC is the lowest concentration of the antimicrobial agent that prevents visible growth of the microorganism.
Why must the tubes be inoculated before agar is poured?
Inoculating the tubes with the desired microorganism before pouring agar ensures even distribution of the microorganism in the agar, promoting growth and forming distinct colonies. This step is crucial for obtaining pure cultures and preventing contamination.

Is a culture media used to support growth of microorganism?
Agar
Why time affect the growth of microorganism?
Because things take time to grow.
What is auxotroph?
An auxotroph is a microorganism which has lost the ability to synthesize an organic compound required for its growth.
Is carbon dioxide or the growth of microorganism a characteristic of life?
Carbon dioxide is NOT a life characteristic.
Why their should a need to maitain temperature?
as every microorganism has their temperature optima at which they show profuse growth.
The process of entrance and growth of a microorganism or virus in the host is called?
The process of entrance and growth of a microorganism or virus in the host is called infection. Infection occurs when the pathogen gains access to the host's tissues, replicates or multiplies within the host, and causes disease symptoms.
What is auxotrophy?
Auxotrophy is the inability of a microorganism to synthesize an organic compound required for its growth, often as the result of a mutation.
What are the disadvantages of the bacteriostatic method?
Bacteriostatic method can only inhibit the growth of microorganism but doesnt completely kill them.
To what decimal place value is the yearly growth measured?
The answer depends on growth in WHAT!
