What else can I help you with?
Macconkey agar is a selective medium and it is also a defined or a undefined medium so why is that a formulation desirable?
This type of agar is designed to grow gram-negative bacteria. It will not grow gram-positive bacteria due to a dye in the formula of the agar.
EMB is a selective medium Is it also a defined or an undefined medium Why is that formulation desirable?
EMB is an undefined selective/differential medium. It contains aniline dyes (methylene blue and eosin), which inhibit the growth of Gram-positive bacteria selecting for Gram-negative bacteria. EMB also contains lactose which makes the media differential based on an organisms ability to ferment lactose
Is EMB agar a defined or undefined medium?
EMB agar is a complex undefined medium because it contains multiple components such as peptone, lactose, agar, and eosin Y and methylene blue dyes that promote the growth of a wide variety of bacteria while inhibiting the growth of certain Gram-positive bacteria.
What is complex medium?
A complex medium is a type of growth medium that contains nutrients of an undefined composition, such as yeast extract or peptone. It is often used in microbiology to support the growth of a wide range of microorganisms that may have diverse nutritional requirements.

What is undefined medium?
Undefined(or complex media) are composed of extracts from plant or animal sources and are rich in nutrients. The exact composition and amount of ingredients are unknown. Undefined media are also great for growing the greatest variety of cultural microbes.
What bacteria strain can grow in an undefined medium of only a carbon source and an inorganic compound?
Sodium acetate
What is complex medium?

What is undefined divided by undefined?
Mathematical operations involving undefined are not permitted. So the answer is undefined.

What is the difference between defined and undefined culture media?
There are two main classifications of culture medianamely defined and undefined. An undefined culture mediumcontains a basic source of aminoacids and nitrogen which are the essential requirements for growth of microorganisms. Common examples of the constituents are beef and yeast extracts. The exact composition and percentage of the individual amino acid or nitrogen providing source is unknown and this is used for basic culture and maintenance of strains. An undefined medium is also called a basal or complex medium. In addition to the aminoacid and nitrogen source it also contains a source for glucose, water and other essential salts.A defined culture medium or synthetic medium is one that contains salts and a glucose source and other components based on the requirements of culture. It contains no yeast or animal extracts. Each of the components used are accurately weighed and the percentage known.
Is 0 over 4 undefined?

What is an undefined quotient?
A quotient in which the numerator or denominator are undefined will be undefined. For example p/q is an undefined quotient until you know something about p and q. Also, if the denominator is zero, the division is undefined.
