Spread plate technique is the method of isolation and enumeration of microorganisms in a mixed culture and distributing it evenly. The technique makes it easier to quantify bacteria in a solution. The spread plate technique involves using a sterilized spreader with a smooth surface made of metal or glass to apply a small amount of bacteria suspended in a solution over a plate.

For its higher productivity, R2A medium should be recommended for heterotrophic plate counts in natural mineral water. This is a preview of subscription content, access via your institution.

Aseptic Laboratory Techniques: Plating Methods

Microorganisms are present on all inanimate surfaces creating ubiquitous sources of possible contamination in the laboratory. Experimental success relies on the ability of a scientist to sterilize work surfaces and equipment as well as prevent contact of sterile instruments and solutions with non-sterile surfaces. Here we present the steps for several plating methods routinely used in the laboratory to isolate, propagate, or enumerate microorganisms such as bacteria and phage. All five methods incorporate aseptic technique, or procedures that maintain the sterility of experimental materials. Procedures described include 1 streak-plating bacterial cultures to isolate single colonies, 2 pour-plating and 3 spread-plating to enumerate viable bacterial colonies, 4 soft agar overlays to isolate phage and enumerate plaques, and 5 replica-plating to transfer cells from one plate to another in an identical spatial pattern. These procedures can be performed at the laboratory bench, provided they involve non-pathogenic strains of microorganisms Biosafety Level 1, BSL

 - Но я не думаю… - С дороги! - закричал Джабба, рванувшись к клавиатуре монитора.  - Это и есть ключ к шифру-убийце. Разница между критическими массами. Семьдесят четыре и восемь десятых. - Подождите, - сказала Сьюзан, заглядывая через плечо Соши.  - Есть еще кое-что.

Use pour-plating and spread-plating methods to determine the concentration of bacteria. Perform soft agar overlays when working with phage.

 Танкадо звонил мне в прошлом месяце, - сказал Стратмор, прервав размышления Сьюзан. - Танкадо звонил вам? - удивилась. Он кивнул: - Чтобы предупредить.

Я люблю. Без воска, Дэвид. Она просияла и прижала записку к груди. Это был Дэвид, кто же. Без воска… Этот шифр она еще не разгадала.

ГЛАВА 115 В голове Дэвида Беккера была бесконечная пустота. Я умер. Но я слышу какие-то звуки. Далекий голос… - Дэвид. Он почувствовал болезненное жжение в боку.
