The incubation period depends on nature of the organism generally it varies between 10-18 hrs. A culture that has reached stationary phase of growth is good for the study. The cell number should be counted and standardized before starting the expt. using serial dilution method. Usually 10 to the power of 5 number cell are taken for doing MIC.
What else can I help you with?
It is thought that submarine canyons on the continental slope have been generated by?
turbidity currents
How do you measure water purity?
Water is usually measured by volume, that is, in liters or gallons. To find the amount of water in a swimming pool, find the volume by multiplying the length, by the width, by the depth. If the pool has a deep end and a shallow end, you can usually estimate the average depth as the same depth as the half-way mark. So a pool 50 meters by 25 meters by 2 meters deep (Olympic size) holds 2500 cubic meters or 2,500,000 liters. Two and a half million liters = 550,000 gallons.
Why do you look at the turbidity when measuring the MIC?
Turbidity is used as an indirect measure of microbial growth in a culture. In the context of measuring Minimum Inhibitory Concentration (MIC), turbidity helps indicate the extent to which a substance inhibits microbial growth. Higher turbidity suggests more growth, while lower turbidity indicates inhibition, helping determine the MIC.
What is the measure of turbidity?
Turbidity is a measure of the cloudiness or haziness of a fluid caused by suspended particles that scatter light. It is typically measured in Nephelometric Turbidity Units (NTU) using a turbidimeter or similar instrument. Higher turbidity values indicate a greater concentration of suspended particles in the fluid.
What causes turbidity in lagoons What is the reliability of turbidity data?
turbidity is pollution, thus runoffs and fertilizer and anything that makes up pollution is turbidity.
How do you test turbidity in sand?
Turbidity in sand can be tested by taking a sample of the sand and mixing it with water in a clear container. After stirring the mixture, observe how quickly the water clears up — the longer it takes for the water to clarify, the higher the turbidity of the sand. Additionally, turbidity can also be measured using a turbidity meter, which provides a numerical value of turbidity in nephelometric turbidity units (NTU).
How do you estimate sulphate ion by nephelo turbidimetric analysis?
Convert sulphate into insoluble form. Most commonly used method for this is reacting the sample with barium chloride in presence of hydrochloric acid. Prepare formazine standards, calibrate nepheloturbidimeter and measure the NTU of the sample. Calculate the concentration of sulphate by extrapolation of the formazine standard curve.
What is the difference between absorbance and turbidity?
Turbidity measures the degree of light is scattered by suspended particulate material and soluble colored compounds in the water. Absorbance measures the amount of light absorbed by the constituents in the water with a specified wavelength.
What is unit of turbidity?
The unit of turbidity is typically expressed in NTU (Nephelometric Turbidity Units) or FTU (Formazin Turbidity Units). Turbidity is a measure of the relative clarity of a liquid and indicates the amount of suspended particles in the water.
What is the turbidity NTU?
The turbidity NTU standards should be less than 5
How can you check turbidity in pure vacuum dried salt?
A dried salt has not turbidity.
The dependent responding variable in this experiment is?
The dependent variable in an experiment is the variable that is measured to determine the effect of the independent variable. It is the outcome or result that is being studied to see how it changes in response to the manipulation of the independent variable.
How does water flow affect turbidity?
i have tested the to doing charts and graphs and when stream flow is fast the turbidity raises and and when the stream flow decreases so does the turbidity
Does adding more lime slurry drop the pH or turbidity?
The pH and turbidity increases.
