What type of instrument is available for measurement of bacterial growth on the basis of turbidity?
A spectrophotometer can be used to measure bacterial growth based on turbidity. It detects changes in light absorbance caused by the presence of bacteria in a liquid culture, with higher turbidity indicating more bacterial growth.
There are other techniques for counting bacteria such as a direct microscopic count and turbidity Why is the standard plate count preferrend for food?
The standard plate count method is preferred for counting bacteria in food because it provides a simple and reliable way to determine the number of viable bacteria present. It allows for the cultivation of various types of bacteria which may be present in the sample, providing a more accurate representation of the bacterial population. Additionally, the standard plate count method is well-established, widely accepted, and can be easily standardized for regulatory purposes in the food industry.
Is there any bacteria growth in a semisolid agar deeps motile?
Bacteria can grow in semisolid agar deeps even if they are motile. Motile bacteria may exhibit visible growth patterns such as streaking or turbidity within the medium due to their ability to move through the agar. It is important to observe for any signs of growth, such as turbidity or swirling in the agar, to determine if bacteria are present and motile.
What is most viable count?
"Most viable count" is a term used in microbiology to refer to the number of viable microorganisms in a sample. It is often determined through techniques like colony counting on agar plates or turbidity measurements. This count is important for assessing the presence and concentration of microorganisms in a sample.
What is the abbreviation of FAU and NTU in chemistry?
NTU : Nephelometric Turbidity Units FAU : Formazin Attenuation Units
Why is turbidity not an accuarte measure of viable bacteria in a culture?
Turbidity measures the cloudiness of a culture, which can be influenced by various factors besides viable bacteria, such as debris or particles in the solution. Viable bacteria may also form clusters or biofilms, which can affect turbidity readings. To accurately measure viable bacteria, other methods such as colony counting or molecular techniques are more appropriate.

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
What are McFarland's standard opacity tubes?
a set of reference tube used to determine the number of bacteria of a suspension using the principle of difference in turbidity with change in cell number
What has the author Diane S Herson written?

identify two source of water turbidity?
Water turbidity can be caused by a number of sources, including suspended sediments, algae, plankton, organic matter, clay, silt, and bacteria. Other sources of water turbidity include industrial and agricultural runoff, wastewater discharge, and natural events such as rainstorms and floods.
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.
Can turbidity be used for testing milk?
Yes, turbidity can be used as a measurement parameter to test milk quality. It assesses the clarity of the milk by measuring the amount of suspended particles in the liquid. Higher turbidity levels can indicate poorer quality or contamination in milk.
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.
