Principle of Microbiological Identification Instrument

The principles of microbial identification instruments mainly include microscopic examination, physiological and biochemical methods, 16s rDNA sequence analysis and microfluidic chip methods. Among them, the microscopic examination method is to observe the morphology of microorganisms, the physiological and biochemical method determines whether it is consistent with the standard strain by detecting the specific physiological and biochemical characteristics of microorganisms, and the 16s rDNA sequence analysis method identifies microorganisms by analyzing the conservative band characteristics of the 16s rDNA gene of the strain. The microfluidic chip method integrates the steps of sample preparation, nucleic acid extraction, PCR amplification and automatic hybridization into a microchip to achieve high-throughput, high-sensitivity and rapid microbial detection
