Isolation identification and application of myxobacteria

Myxobacteria is a kind of gram-negative bacteria. As higher prokaryotes, myxobacteria is widely distributed, and it can glide and prey on other bacteria. Myxobacteria have many species and can live in various extreme environments. Due to its special predation characteristics and abundant secondary metabolites, more and more researchers have paid attention to it in recent years. According to these characteristics, myxobacteria have been widely used in agricultural disease prevention and control, medical disease research, food safety and preservation, environmental management and protection, etc. However, because the current technical means are not enough to excavate all kinds of myxobacteria species, the research on their separation and classification is still slow. This thesis summarizes the methods and status quo of myxobacteria isolation and identification in recent years, research progress on predation and secondary metabolites of myxobacteria in different disciplines and fields. On this basis, the bottleneck of myxobacteria research and its future prospects are put forward.
