Classification of Bacteria by MALDI-TOF MS Based on Ribosomal Protein Coding in S10-spc-alpha Operon at Strain Level

Identification of bacteria is associated with the environmental management and clinical microbiological testing in the food and pharmaceutical field, etc. The identification methods most commonly applied are morphological observation, physiological and biochemical characteristics testing, and DNA sequence analysis.
Simple identification at the genus to species level is conducted by DNA sequence analysis, in which the 16S rRNA gene sequencing technique has become widely used in recent years; however, the following shortcomings of this approach underscore the need for a new microbial identification method.
