3, microbial separation, purification and culture technology

Isolation and purification: from the mixed microbial population obtained only one or a strain of microorganisms in the process.

Why pure culture: a single plate on the flat does not necessarily guarantee that it is a kind of bacteria.

Common separation and purification methods:

Single-cell pick-up dilution method of coating plate

Dilution mixing plate method flat line method

Dilution coating method:

Steps:

1, inverted plate: beef peptone medium, Gao I medium, Charcteric's medium is cooled to 55-60 ° C, after mixing down the plate, beef peptone medium inverted 4 dish, high I medium and Char's medium each down 3 dishes.

2, Preparation of sewage dilution: 10g soil samples, add 90ml sterile water, shaken in a triangular flask 20min. Take 0.5ml added 4.5ml sterile water in the test tube, and so forth, made of different dilutions.

3. Coating: Dilute the bottom of each culture medium plate above, and then use a sterile pipette to pipette 0.1 ml of columbarium from the tubes of the last three dilutions, 10-4, 10-5 and 10-6 Into the flat, with glass rod coating.

4, training: Gao I and Cha's inverted culture in a 28 ℃ incubator cultured 3-5days, beef peptone agar medium at 37 ℃ for 1-2days.

5, pick colony: Go to the ramp, check whether the same, save.
