The liquid medium has a uniform distribution of nutrients and is easy to control the growth and metabolism of microorganisms. The medium that is cooled to 55 ~ 60 C is placed in a large Erlenmeyer flask. Therefore, it is only suitable for scientific research, such as nutrition and metabolism. 3) Identification medium Adding a certain reagent or chemical to the culture medium makes the indistinguishable microorganisms show obvious differences after being cultured, thus helping to quickly identify a certain microorganism. Because various microorganisms have different nutritional requirements and different culture purposes and detection needs, there are many types of media.
Micro-sampler (covering 1-1000ul) 2. (3) The Disposable Plastic Ware used for sample processing cannot be used as tools for ordinary molecular cloning, nor can they be used to manipulate target sequences. Experiment to see if the reagents are satisfactory, and then aliquot them into a quantity that is only sufficient for one use for storage. Mobile UV lamp (near the work surface) 5. Micro-sampler (covering 1-1000ul) 3. It is a molecular biology technique used to amplify specific DNA fragments and can be regarded as a special DNA replication outside the organism. ⑸
Large-volume samples should be pipetted using individually packaged sterile disposable pipettes.025% sodium azide to the amplification reagent or sample preparation reagent does not inhibit the amplification reaction. All solutions used should be free of nucleic acid and / or nuclease (DNase and RNase) contamination. The lab coat should be dedicated to the sample preparation room and cleaned frequently. ⑹ Newly prepared reagents should be tested before they are used to prepare new specimens. Gloves should be changed frequently, especially during each step of the extraction process.
The mouth of the container can be closed with a cotton plug with moisture-proof paper, and the outside must be wrapped with waterproof paper (currently test tubes usually have screw caps). It is best to use a stainless steel pan for heating and melting. It is formulated with chemicals of known chemical composition. Bile salts have the ability to inhibit bacteria other than intestinal bacteria (selectivity). 3. 3. Agar, gelatin, silica gel, etc.
