Method for detecting starch degrading microorganisms in tobacco leaf
A starch degradation and microbial technology, applied in the field of microbial detection, can solve the problems of inability to form a complete and unified tobacco leaf fermentation technology, lack of in-situ information of starch degrading bacteria groups, and inability of fermentation conditions to be suitable for action conditions, and achieve accurate experimental results and cost. Low, the effect of improving the quality of taste absorption

Example Embodiment
[0037] Example 1: A method for detecting starch-degrading microorganisms in tobacco leaves, the steps are as follows:
[0038] Sample collection: Wear sterile gloves and use a disposable sterile collection bag to randomly collect 1kg tobacco leaf samples during baking or aging, and store them at 37°C under constant temperature conditions and send them to the laboratory for sample processing within 20 minutes;
[0039] Sample processing: In the laboratory, first use 70% alcohol to sterilize scissors. Under aseptic conditions, cut the tobacco leaf sample into 1-4cm with sterilized scissors 2 Small pieces, and carefully remove useless tissues such as stems and veins of tobacco leaves;
[0040] Dilute the sample: under aseptic conditions, use a sterile 50ml beaker to weigh 30g of fresh broken leaf sample, add 300ml sample treatment reagent A, and mix with the broken leaf sample evenly;
[0041] Cell separation: Pour the mixed liquid into a Philips (PHILIPS) household mixer for 3 minutes ea...

[0065] Embodiment 3: A method for detecting starch-degrading microorganisms in tobacco leaves, the steps are as follows:
[0066] Sample collection: Wear sterile gloves and use a disposable sterile collection bag to randomly collect 1 kg of tobacco leaf samples during baking or aging, and store them at a constant temperature of 25°C and send them to the laboratory for sample processing within 20 minutes;
[0067] Sample processing: In the laboratory, first use 70% alcohol to sterilize scissors. Under aseptic conditions, cut the tobacco leaf sample into 1-4cm with sterilized scissors 2 Small pieces, and carefully remove useless tissues such as stems and veins of tobacco leaves;
[0068] Dilute the sample: under aseptic conditions, use a sterile 50ml beaker to weigh out 50g of fresh broken leaf sample, add 1000ml sample treatment reagent A, and mix with the broken leaf sample evenly;
[0069] Cell separation: Pour the mixed liquid into a PHILIPS household mixer for 5 minutes each time, a...
