How is turbidity of a bacterial culture measured?
The density of the bacterial cells in the liquid suspension. It's an indirect measure of number of cells. Using a spectrophotometer, light is passed through a sample and the light that passes through is measured by a receiver. The idea is that the less light passing through (because of the cloudiness) the more cells there are. The level of turbidity can be called the 'absorbance' or 'optical density (OD)', as measured by a spectrophotometer.
What does turbidity mean?
Turbidity is a measure of how murky water is. Very turbid water is very hard to see through. It is caused by usually unseen particles (like small soil particles) in the water.
What is the measure of turbidity?
That is cloudiness and brown colour in water. Not always harmful, but a good idea to get a sample to a lab and analyse it.
The measure of the total amount of solid material dissolved in seawater is called .?
salinity
What is a YSI used for?
A YSI is a sampling device that can be used to measure parameters in the water column such as temperature, salinity, depth, pH, oxygen, turbidity, and chlorophyll.
Why is turbidity not an accuarte measure of viable bacteria in a culture?
why is turbidity not an accurate measurement of viable bacteria in a culture

Is turbulence the same as turbidity?
No, turbulence and turbidity are not the same. Turbulence refers to the chaotic movement of fluids, such as air or water. Turbidity, on the other hand, is a measure of how cloudy or murky water is due to the presence of suspended particles like silt or organic matter.
What is a measure of how clear water is in a water system?
This is 'turbidity' and is measured in 'ppm' when you have a water sample analysed in a lab.

What is meant by the term turbidity?
Turbidity, also referred to as haze. Is a measure of suspended solids that are generally individually invisible to the naked eye. It can be used to describe haziness in glass or plastic and is also a key method of measuring water quality.
What unit is for cloud cover?
Cloud cover is usually given as a percentage, there is no unit of measure.

What machine is used to count platelets in an aggregation test?
The platelet aggregation test uses a machine called an aggregometer to measure the cloudiness (turbidity) of blood plasma
How could you tell the bacteria were growing in the culture?
Bacteria growing on a petri dish can have more than one bacteria growing on it, but different characteristics can be seen like cilia, motility and color. To know more specifically what those other bacteria strains are, get a sample and grow it on agar by itself.
