Peptone water is used in the dilution technique because it provides a nutrient-rich environment that supports the growth of bacteria. This allows for easier detection and enumeration of bacteria present in samples. Peptone water also helps maintain bacterial viability during dilution procedures.

Why peptone is an ingredient in TSA media?

There are two Peptone used in TSA media:1. Casein peptone2. Soya peptoneCasein peptone and Soya peptone provide nitrogen, vitamins and minerals. The natural sugars from Soya peptone promote bacterial growth.


What is helium dilution technique?

Helium dilution technique is a method used for measuring lung volumes such as total lung capacity and residual volume. It involves the subject breathing a known volume of helium gas from a spirometer, which then mixes with the gas in the lungs. By analyzing the change in helium concentration, lung volumes can be calculated.


Why would peptone ion agar be used in a biochemical test?

Peptone ion agar is often used in biochemical tests to provide a source of nutrients for microbial growth. It contains peptone, which is a source of amino acids and peptides that promote the growth of bacteria. Peptone ion agar can support the growth of a wide range of microorganisms and is commonly used in tests such as the oxidase test or the indole test.


What is the function of buffered peptone water?

Buffered peptone water is a liquid medium commonly used to enrich and support the growth of various microorganisms in food and water samples. It helps to maintain a suitable pH level and provides necessary nutrients for bacterial growth during microbiological testing and analysis.


What does peptone broth contain?

Peptone broth is a material commonly used in a lab. Scientists and research scientists use it to culture the growth of Salmonella and Shigella.

What is the difference between peptone water and the saline?

Peptone water is a liquid medium containing peptone (protein digest) and water, often used for bacterial growth and enrichment. Saline is a solution of sodium chloride (salt) in water, commonly used for cleaning wounds or as a nasal spray. Peptone water serves as a nutrient source, while saline is primarily used for hydration or wound care.


What is the differences between a streak plate technique and a serial dilution technique?

A streak plate technique is used to isolate individual bacterial colonies on a solid agar plate to obtain pure cultures, while a serial dilution technique is used to dilute a bacterial sample in a series of steps to obtain a range of concentrations for further analysis. Streak plate technique is qualitative, focusing on colony isolation, while serial dilution technique is quantitative, focusing on estimating bacterial concentration.


What are the solutions that are most used for IV PB dilution?

The most common solutions used for intravenous phenobarbital dilution are sterile water for injection (SWI) and normal saline (0.9% sodium chloride). These solutions are preferred because they are compatible with phenobarbital and maintain its stability for administration. It's important to follow proper dilution guidelines and use aseptic technique to minimize the risk of contamination.

What is high dilution technique?

High dilution technique is a method used in homeopathy to prepare remedies by repeatedly diluting a substance in water or alcohol and vigorously shaking it between each dilution. This process is believed to imprint the energetic essence of the original substance onto the solvent, resulting in the desired medicinal effect without the presence of the original substance.


What is the molecular formula of peptone?

peptone water is used as a growth medium and as a carbohydrate fermentation media. peptic digest of animal tissue(peptone) = 10.0 gm/ltr NaCl= 5.0 gm/ltr water = 1000 ml ph( at 25 degree centigrade ) = 7.2 incubation period & temp. = 35-37 C. for 18-24 hrs


Is carbon in peptone?

Yes, peptone is a nutrient source often used in microbiological culture media, derived from partially digested proteins like meat or casein. Since proteins contain carbon, peptone would also contain carbon.

What is the explanation for tenfold dilution technique?

In ten fold dilution we add one part of the sample into the nine part of the diluent e.g. water. It will make it ten fold dilute. If we have series of tubes to dilute then after making the ten fold dilution in first tube, take the dilute sample from the first tube in same quantity as we added sample in first tube and add it to 2nd one. then then take the same quantity from 2nd one and add to third one and so on......... from the last tube we take the adjusted quantity of dilute sample and discard it. This will make the series of ten fold dilution. If you add one part substance to 10 parts of water, you get an 11-fold dilution.
