What is medium preparation?
The general methodology for a medium preparation involves preparation of stock solutions (in the range of 10x to 10Ox concentrations) using high purity chemicals and demineralized water. The stock solutions can be stored (in glass or plastic containers) frozen and used as and when required. Most of the growth regulators are not soluble in water. They have to be dissolved in NaOH or alcohol.
How long does it take to sterilize a culture medium?
The culture medium is usually sterilized in an autoclave at 121°C and 15 psi for 20 minutes. Hormones and other heat sensitive organic compounds are filter-sterilized, and added to the autoclaved medium.

In practice, 3-5 different concentrations of growth regulators in different combinations are used and the best among them are selected. For the selection of appropriate concentrations of minerals and organic constituents in the medium, similar approach referred above, can be employed.
What are the two parameters that determine the composition of a culture media?
Composition of Media: The composition of the culture media is primarily dependent on two parameters: 1. The particular species of the plant. ADVERTISEMENTS: 2. The type of material used for culture i.e. cells, tissues, organs, protoplasts.

These include iron, manganese, zinc, boron, copper and molybdenum. Among the microelements, iron requirement is very critical. Chelated forms of iron and copper are commonly used in culture media.
What is the energy source used in plant culture?
Among the energy sources, sucrose is the most preferred. During the course of sterilization (by autoclaving) of the medium, sucrose gets hydrolysed to glucose and fructose. The plant cells in culture first utilize glucose and then fructose. In fact, glucose or fructose can be directly used in the culture media.

Getting Started
Media Preparation
- Media preparation is a crucial step, and you need to develop a system for your step-by-step routine. Just imagine it as a cooking recipe! If you are starting in plant tissue culture, you can opt for commercially availablepowder mixes. Although each culture medium has a somewhat distinct preparation methodology, the steps outlined below detail how to properly prepare media for tiss…
Stock Solutions, Why Prepare them?
- Stock solutions are concentrated solutions of chemicals that are prepared in advance and used to make several batches of media. The use of stock solutions reduces the number of repetitive steps in media preparation and hence, the chance of human or experimental error. To prepare them, components are often dissolved in distilled water to get the desired concentration. These soluti…
Dispensing The Medium
- When the medium is ready, the next step is dispensing it into the vessels where the tissue cultures will grow. It is efficient to dispense after sterilization into pre-sterilized vesselsinside a laminar flow. An alternative solution would be to autoclave the glass growth vessels with media. The dispensing can be done in different ways, where, in ou...
Ensuring Success
- The correct preparation of the culture medium will determine the success of your experiments. However, you can encounter difficulties such as precipitation and contamination. To avoid both, we give you the following tips: 1. You should wear gloves, hair nets, mouth masks, and lab coats. 2. You should never pour excess stock solution back into the original stock solution container a…
