Most of Gram+ bacteria and for Gram- ones, Segnilliparus spp.
general purpose medium is a media that provides enough nutrients in which most any microorganism will utilize for growth. Allows for a wide variety of microorganisms to grow. It can be used for a wide range of applications including; culture storage, enumeration (counting), isolation of pure cultures or simply general culture. e.g. Tryptocase Soy Agar (TSA) Tryptocase Soy Broth (TSB) Nutrient Agar
in my opinion, cultivating microbes on slant agar is carried out when we do not know anything about the microbe. slant agar is a nutrient rich medium that allows most microorganism to grow. therefore, we could obtain a pure sample of the microorganism.
Nutrient agar is typically the best culture media for the growth of most chemoheterotrophic organisms. It provides a simple and balanced nutrient source that can support the growth of a wide variety of organisms by supplying essential nutrients, vitamins, and minerals required for their growth.
It is possible for E. coli to outcompete M. luteus on a nutrient agar if the conditions are more favorable for E. coli growth. E. coli is known for its fast growth rate and adaptability, which can give it a competitive advantage over other bacteria in certain environments. Factors such as nutrient availability and pH levels can also influence which species will dominate in a mixed culture.
Non-nutrient agar is a type of agar medium that does not contain any nutrients suitable for supporting the growth of most bacteria. Instead, it is often used for cultivating non-bacterial organisms like fungi, protozoa, and algae. Non-nutrient agar is generally used for the isolation and cultivation of these specific types of microorganisms.
Agar is generally made by mixing the powdered form with varying ingredients. The powder is based on seaweed extract for nutrient agar, and nutrient agar is generally a base for most other agars - eg. Horse Blood Agar is nutrient agar with horses blood added; Choc agar has defibrinated (cooked) horses blood added.
Nutrient agar is used for bacteria because it contains nutrients like amino acids, vitamins, and minerals suitable for bacterial growth. Fungi typically require more complex nutrients and specialized media for cultivation, such as Sabouraud agar. Nutrient agar may lack specific nutrients needed for fungi to grow and reproduce effectively.
blood or nutrient agar would work, but blood agar will most likely grow more bacteria.
Most of Gram+ bacteria and for Gram- ones, Segnilliparus spp.
Nutrient agar plates: used for general growth of most bacteria. Blood agar plates: used to differentiate bacteria based on their ability to hemolyze red blood cells. MacConkey agar plates: used to differentiate lactose-fermenting bacteria from non-lactose fermenters based on their ability to grow and ferment lactose.

Different nutrient agars have different ingredients in them. Agar itself is a polysaccharide (sugar) composed of galactose. Most agars contain some sort of soybean or lipids and also amino acids. Many contain peptone, which is a mixture of polysaccharides and protein.
Luria agar is Luria broth with the addition of 15 grams per liter agar. Agar is a solidifying agent that makes the liquid media solid at room temperature. Hence, luria agar would be a petri dish of agar while luria broth would be liquid to go in a tube or flask.
