• Intended Use: Phenylethanol Agar is used with blood for the selective isolation of Gram-positive cocci. • Product Summary and Explanation: Brewer and Lilley reported the addition of phenylethanol to a nutritive medium permi
Phenylethanol agar (no. 0504, Difco), which was used in this laboratory, alters both thecolonial morphologyandhemolysisofgram-positive isolates and also fails to kill Proteus . and, for this purpose, overnight incubation seemedmostappropriate. Occasional strains of potential pathogens
Differential Media. Such a medium normally consists of a mixture of protein digests (peptone, tryptone, etc.) and inorganic salts, hardened by the addition of 1.5% agar. Examples of standard general purpose media that will support the growth of a wide variety of bacteria include nutrient agar, tryptic soy agar, and brain heart infusion agar.
Phenylethyl Alcohol (PEA) Agar. Purpose: A selective medium used to inhibit the growth of Gram negative organisms. Principle: PEA prevents the growth of Gram-negative organisms by disrupting the sturcture of lipids in the Gram-negative membrane. It also can hamper protein synthesis. PEA is present in this medium at 0.025%, if the concentration .
Desoxycholate Agar. Desoxycholate Agar is a Selective & Differential Medium. The selective and differential aspects are due to desoxycholate, lactose, and the pH indicator Neutral Red in the medium. It is Selective because it encourages some bacteria to grow while inhibiting others. Desoxycholate generally inhibits Gram positive bacteria from .

The purpose of peptone in the nutrient agar medium is to provide the primary source of organic nitrogen for the growing microbial culture, and it can also be a source of carbohydrates and vitamins. The exact composition of peptone in the nutrient medium will differ depending on the protein source and method of …
Use: Phenylethyl alcohol is the main component of Rose oils obtained from rose blossom. It also occurs in Neroli, Ylang-Ylang, Carnation and Geranium oils. Phenylethyl alcohol has mild rose odour. It is used in large quantities as a fragrance material not only for rose compositions but for other blossom notes.

Differential Media. Isolation of bacteria is accomplished by growing ("culturing") them on the surface of solid nutrient media. Such a medium normally consists of a mixture of protein digests (peptone, tryptone, etc.) and inorganic salts, hardened by the addition of 1.5% agar.
Aug 15, 2019· Mannitol Salt Agar (MSA) is used as a selective and differential medium for the isolation and identification of Staphylococcus aureus from clinical and non-clinical specimens. It encourages the growth of a group of certain bacteria while inhibiting the growth of others.
2) When Staphylococcus epidermidis is incubated on a Petri dish of Phenolethanol agar, individual cells grow into visible colonies. But when Esherichia coli is plated on this. medium, it dies. In this respect phenolethanol agar is an example of: A. a general purpose medium B. a differential medium

Mannitol salt agar is selective as well as differential. It is selective because, this growth medium contains a good amount of salt, thereby inhibiting the growth of almost all bacteria, except those in the genus Staphylococcus. So it is used for isolating staphylococci bacteria.

However, pigment develops more rapidly than on non-selective Brucella Agar with H and K (. no. AG301). The basal medium of Anaerobic PEA consists of pancreatic digest of casein and enzymatic digest of soybean meal. Both provide amino acids, carbohydrates, and vitamins.
Blood agar is an enriched, bacterial growth medium. Fastidious organisms, such as streptococci, do not grow well on ordinary growth media. Blood agar is a type of growth medium (trypticase soya agar enriched with 5% sheep blood) that encourages the growth of bacteria, such as streptococci, that otherwise wouldn't grow.
Phenylethyl Alcohol Agar is formulated as per Lilley and Brewer (1) for the selective isolation of gram-positive bacteria. This medium can be supplemented with 5 % sheep blood. This medium is especially useful when specimens are contaminated with swarming Proteus species. It is also useful in the diagnostic studies of wounds and exudate .
