Differences in Soil Microbiota of Continuous Cultivation of <i>Ganoderma leucocontextum</i>

Abstract

The tendency of microbiota changes in the soil of Ganoderma leucocontextum continuous cultivation is investigated by high-throughput sequencing technology. Medium bag cultivation of G. leucocontextum with uncultivated soil significantly increased the organic matter (OM), hydrolyzable nitrogen, available phosphorus, and available potassium content of soil. The relative abundance of the dominant beneficial bacteria (Sphingomonas spp., Mucilaginibacter spp., Bryobacter spp., and Bradyrhizobium spp.) for G. leucocontextum continuous cultivation, was decreased in the soil. Mortierella spp. and Pyrenochaeta spp. were the dominant fungi with negative effects on G. leucocontextum cultivation in the soil. The correlations between the microbiota and soil physicochemical properties indicated that continuous cultivation not only caused changes in the soil physicochemical factors but also affected the structure of dominant microbial communities, especially bacteria and environmental factors.
