Incubate the plate at 25°C or 37°C. Examine the milk agar plate cultures for the presence or absence of a clear area, or zone of proteolysis, surrounding the growth of each of the bacterial test organisms. A litmus test is an indicative test that is used in chemistry to find the general acidity or alkalinity of the substance (liquid or gas) using litmus paper. A litmus paper is made of a dye based on lichens and it turns pink or red in an acid (pH < 6.0) whereas it turns blue in a base (pH > 8.0). . (milk, wine, juices, etc.) and food industry .Litmus Milk is the most useful medium in dairy industry as it is a reliable indicator of bacterial action on milk (3). Litmus is a good indicator of acidity, alkalinity and its oxidation-reduction potential is useful in milk media with lower toxicity to microorganisms than bromocresol purple (4).

PMC274675. As a library, NLM provides access to scientific literature. Inclusion in an NLM database does not imply endorsement of, or agreement with, the contents by NLM or the National Institutes of . The litmus test is performed by placing a small drop of sample onto the colored paper. Usually, litmus paper is either red or blue. Red paper turns blue when the pH is alkaline, while blue paper turns red when the pH turns acidic. While litmus paper is most often used to test the pH of liquids, it can also be used to test gases if the paper is . A positive result is a pink or red color on the litmus paper (Figure 6.68c). If the sample doesn't dissolve in water, instead dissolve the same amount of unknown in \(1 \: \text{mL}\) of ethanol. Add enough .Litmus paper is a piece of paper that produces a result which can be used as a pH indicator. Litmus is mainly used to assess whether a solution is acidic or basic. The colour transition occurs over the pH range 4.5–8.3 at .

Litmus is a water-soluble mixture of different dyes extracted from lichens.It is often absorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity.In an acidic medium, blue litmus paper turns red, while in a basic or alkaline medium, red litmus paper turns blue. In short, it is a dye and indicator which is . BACKGROUND. Milk is a very complicated source of nutrition that consists of protein in an aqueous solution of lactose and minerals. When bacteria are inoculated in this milk, the enzymes secreted by bacteria may bring about changes in the media. 1 Litmus is added identify any changes in the pH. So, the main objective of this test is to differentiate .

Only P. aeruginosa colonies gave clear zones due to hydrolysis of casein together with diffused green pigment. Results on milk agar correlated well with .

1. Wet 2 pieces of litmus paper. A litmus test works best with gases that are dissolved in water (an aqueous solution). To achieve this on a small scale, you only need to wet the paper with water. When the gas touches the wet paper, some of it will dissolve into solution right on the test strip. 2.
