摘要： Ganoderma lucidum is a medicinal mushroom usually cultivated in logs and covered with soil. Its production decreases after continuous cultivation. Changes of microbial diversity in soil are suggested to be one of the reasons. This study aims to investigate the changes of microbial diversity and abundance in soil during cultivation, and isolate potential microbial strains that affect the yield of G. lucidum. Soil samples were collected at two different ranges from logs during one complete growth cycle of G. lucidum. The changes in fungi and bacteria were investigated by using high-throughput sequencing and real-time PCR. Results indicated that the relative abundance of Firmicutes in the bacterial community decreased at the short-range site. In the fungal community, the relative abundance of Ganoderma increased to 70% at the long-range site at the end of the cultivation. The abundance of bacteria and fungi decreased significantly at the end of the growth cycle. Recovery of microbial changes in soil should be proceeded separately based on different ranges to logs. The microbial strains in these soil samples were also isolated and identified. Potential strains were assessed in the form of bio-fertilizer. The yield of G. lucidum in the field using bio-fertilizer with isolated bacterial strains from the Firmicutes phylum was about 13% higher than that without using bio-fertilizer, suggesting the possibility of alleviating the production decrease of G. lucidum by this method.
