Effects of different cultivation conditions on cultivable microorganisms in wheat rhizosphere
The rhizosphere microbial community of plants has a significant impact on their healthy growth,and isolating and cultivating their microorganisms is of great significance for promoting crop growth and yield increase.During the process of microbial cultivation,the type of culture medium and oxygenation capacity have different effects on the enrichment of rhizosphere microorganisms.This study used 16S rRNA high-throughput sequencing technology and bioinformatics analysis to analyze the characteristics and functions of wheat rhizosphere bacterial communities under different cultivation conditions.Research has shown that the microbial community in the rhizosphere of wheat is mainly composed of γ-Proteobacteria,Bacteroides,and Bacillus,and the type of culture medium and oxygen content significantly affect their abundance.The functional prediction of FAPROTAX indicated that the dominant microbial community in wheat rhizosphere microorganisms is mainly related to functions such as chemical heterotrophic,fermentation,carbon cycling,nitrogen cycling,and iron respiration,which played an important role in plant growth and development.The research results provided important basis for the cultivation of wheat rhizosphere microorganisms and the development and utilization of microbial resources.
