Using a new agar plate, lift the lid just enough to insert the loop. Streak the loop containing the bacteria at the top end of the agar plate moving in a zig-zag horizontal pattern until 1/3 of the plate is covered. Sterilize the loop again in the flame and cool it at the edge of the agar away from the bacteria in the plate that you just streaked.
It contains two dyes in the ratio of 6:1 and is both toxic to gram-positive microorganisms. It is both a selective and differential mediums for coliforms.

Buy nutrient agar from Amazon or Ebay.One pack contains 12.5 grams of nutrient agar which is for 500ml water. Measure 500ml (17 fl. oz.) bottle water (tape water or filtered water will do) with measuring cup and pour it into a clean steel stock pot (you can add up to 550ml, which wouldn’t affect medium solidification). 2017-02-28 · Using a single colony from a freshly streaked agar plate to inoculate a bacterial culture for DNA purification will minimize the chance of having a mixture of plasmids in your purified DNA. This protocol explains how to isolate a single bacterial colony by streaking it onto an LB agar plate.
Bacteria on Agar Yeast on Agar the Colony morphology is good indicat Evaluating bacteria on agar plates is one method of identification used by microbiologists. Colony morphology, or the physical characteristics of bacteria as it multiplies, generally cannot be seen using other diagnostic methods. The shape, color, surface appearance, and even smell of a bacterial colony can help confirm an identification. Introduction. Blood Agar is an important clinical medium. It is both enriched and differential. The blood contains many nutrients that help support “fastidious” bacteria, those that need additional or particular types of nutritional support.
agar plates containing bacteria, cell cultures, human blood and materials that have been in contact with them.
Introduction. Blood Agar is an important clinical medium. It is both enriched and differential. The blood contains many nutrients that help support “fastidious” bacteria, those that need additional or particular types of nutritional support. Many bacteria can hemolyze blood, partially or completely, and these hemolysis patterns can help
Sequencing provides a more robust toolset, since it can identify both viruses and unculturable microbes. Most bacteria will grow well using nutrient agar, but some more fastidious bacteria prefer tryptic soy agar.

Sterilize the loop again in the flame and cool it at the edge of the agar away from the bacteria in the plate that you just streaked. Nutrient agar is popular because it can grow a variety of types of bacteria and fungi, and contains many nutrients needed for the bacterial growth. Composition of Nutrient Agar. 0.5% Peptone; It is an enzymatic digest of animal protein. Peptone is the principal source of organic nitrogen for the growing bacteria.
