3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Biological products
Products obtained using biotechnology.
Note. The biological products in this standard refer specifically to products containing photosynthetic bacteria.
3.2
Photosynthetic bacteria photosyntheticbacteria
Prokaryotes with a primitive light energy synthesis system, the general term for bacteria that can carry out oxygen-free photosynthesis under anaerobic conditions.
Note. specifically refers to non-oxygen-producing photosynthetic bacteria, especially purple non-sulfur bacteria. Belongs to Proteobacteria (Alpha Proteobacteria) red
Rhodospirilales, Rhizobiales, Rhodobacterales, including Rhodospirillum rubrum, Rhodospirillum chrysosporum, swamp
Rhodopseudomonas, Rhodobacter capsularis, Rhodobacter sphaeroides, etc.
3.3
Polynucleotide polymorphism; MNP
Sequence polymorphism caused by multiple nucleotides within a nucleotide region.
4 Principle
After the sample to be separated is diluted, it is inoculated in a selective medium, and single cells grow and reproduce to form bacteria visible to the naked eye.
drop. Count the photosynthetic bacteria in biological products according to the number of colonies on the plate and the physiological and biochemical and MNP identification results of the selected colonies.
5 Reagents or materials
The reagents used in this method are analytically pure. Unless otherwise specified, the experimental water is all secondary water specified in GB/T 6882.
