[Preface for microbiome sequencing and analysis].

Microbes are the most important commensal organisms in humans, animals and plants, and are the major habitants in soil, sediment, water, air and other habitats. The analysis of microbiome in these habitats has become a basic research technique. As a fast developing technology in recent years, microbiome sequencing and analysis have been widely used in human health, environmental pollution control, food industry, agriculture and animal husbandry and other fields. In order to sort out and summarize the current status, development and application prospects of microbiome sequencing and analysis technologies, this special issue has prepared a collection of 16 papers in this field, that comprise sample preservation and processing, single microbe genome sequencing and analysis, and microbiome feature analysis in special habitats, microbiome related databases and algorithms, and microbiome sequencing and analysis expert consensus. It also introduced in detail the development trend of the microbiome sequencing and analysis, in order to promote the rapid development of the microbiome sequencing and analysis industry and scientific research in China, and provide necessary reference for the healthy development of related industries.
