“…It is favorable to the balanced supply of multiple nutrients(Zhang et al, 2017;. The results of this paper showed that short-term application of lees biochar can signi cantly improve the pH, SOM, TN, AN, NN, AP and AK content of the yellow soil in Guizhou, which is similar to the results of previous studies(Liu et al, 2019;. Maotai lees are a by-product of sorghum and other byproducts formed after many high temperature fermentations.…”

“…Soil microbial community structure is not only in uenced by physical factors such as soil moisture and aeration conditions, but also soil chemical factors such as pH, SOM and TN are key factors in uencing the changes in soil microbial community structure (Liu et al, 2019). Results of RDA redundancy analysis in this study showed that SOM, AN, and NN were important factors in uencing the structural changes of fungal communities in yellow soil.…”

In order to realize the resource utilization of Guizhou sauce-avor distiller's grains and the improvement of yellow soil fertility, a eld experiment was carried out to study the effects of short-term application of vinasse biochar on soil nutrients and the diversity of fungal community structure by setting ve biochar dosages of 0% (MB 0 ), 0.5% (MB 0.5 ), 1.0% (MB 1.0 ), 2.0% (MB 2.0 ), and 4.0% (MB 4.0 ). The results showed that the application of lees biochar increased the pH, soil organic matter (SOM), total nitrogen (TN), ammonium N (AN), nitrate N (NN), available phosphorus and available potassium of the yellow soil to varying degrees, but decreased the microbial biomass carbon (MBC) and microbial biomass N (MBN) by 12.36%-26.49% and 34.10%-59.95% respectively. The application of lees biochar signi cantly reduced the number of fungal OTUs and community diversity. Compared with MB 0 treatment, the application of lees biochar signi cantly changed the structure of the fungal community. The relative abundances of Mortierellomycota, Basidiomycota, Glomeromycota, and Chlorophyta were all increased in varying degrees, but the relative abundance of Ascomycota was signi cantly reduced by 23.86%-29.06%. At the same time, the application of lees biochar also increased the relative abundance of some functional bacteria, such as Mortierella and Chaetomium, and reduced the relative abundance of some pathogenic bacteria, such as Aspergillus and Fusarium. In addition, the results of redundant analysis showed that SOM, AN and NN were the main environmental factors that affect the change of yellow soil fungal community structure. In summary, the short-term application of lees biochar can increase the nutrient content of soil, change the structure and diversity of soil fungal communities, and also can reduce the relative abundance of some pathogenic bacteria, which can inhibit the growth and reproduction of harmful plant pathogens.

“…Chen et al [ 15 ] stated that the biochar addition to the organic carbon-poor dry soil enhanced the soil microbial diversity and abundance. Liu et al [ 16 ] also reported that biochar substantially improved soil fertility and yield by increasing the relative abundance of soil fungi and bacteria and changed the community structure. A large number of experiments have focused on the microbial effects of biochar and chemical fertilizers, but most of the reports devoted more attention to bacteria [ 17 , 18 , 19 ].…”

Response of Soil Fungal Diversity and Community Composition to Varying Levels of Bamboo Biochar in Red Soils

Soil fungi play a vital role in soil nutrient dynamics, but knowledge of their diversity and community composition in response to biochar addition into red soil is either limited or inconsistent. Therefore, we determined the impact of bamboo biochar (BB) with increasing concentrations (0, 5, 20, and 80 g kg−1 of soil, referred to as B0, BB5, BB20, and BB80, respectively) on soil physicochemical properties and fungal communities (Illumina high-throughput sequencing) in red soil under Fokenia hodginsii (Fujian cypress). We found that increasing BB levels effectively raised the soil pH and soil nutrients, particularly under BB80. BB addition significantly increased the relative abundance of important genera, i.e., Basidiomycota, Mucoromycota, and Chytridiomycota that could play a key role in ecological functioning, e.g., wood degradation and litter decomposition, improvement in plant nutrients uptake, and resistance to several abiotic stress factors. Soil amended with BB exhibited a substantial ability to increase the fungal richness and diversity; BB80 > BB20 > BB5 > B0. Basidiomycota, Mucoromycota, Glomeromycota, Rozellomycota, Aphelidiomycota, Kickxellomycota, and Planctomycetes were positively associated with soil pH, total nitrogen, phosphorous, and carbon, and available potassium and phosphorous. Besides, the correlation analysis between the soil fungal communities and soil properties also showed that soil pH was the most influential factor in shaping the soil fungal communities in the red soil. These findings have significant implications for a comprehensive understanding of how to ameliorate acidic soils with BB addition, as well as for future research on sustainable forest management, which might increase soil fungi richness, diversity, and functionality in acidic soils.

“…Recently, several papers confirmed the capability of fungi to solubilise various types of coal (Yuan et al, 2006, Kliaĭn et al 2013 or to remove not desired constituents of coal (Etemadzadeh et al, 2016). Supporting effects of bacteria (Liu et al, 2019) or plants (Mukasa-Mugerwa et al, 2011) in the fungal attacks of coal have been observed. The aim of this study was to determine whether fungi of genus Trichoderma residing within lignite have higher lignite-solubilisation potential than their counter-parts collected from the Earth surface.…”

The ability of Trichoderma strains isolated from lignite and of Earth surface-derived strains to attack (solubilise) lignite, peat and wood was compared using glutamate as a carbon source. The results showed that lignite-derived microorganisms solubilise lignite to similar extent as Trichoderma strains isolated from the Earth surface. Solubilisation processes involve the action of enzymes and alkaline pH. The solubilisation of lignite was accompanied by a small increase of conidia-bound laccase, whereas that of peat was accompanied by (secretion) activity of cellulase, laminarinase, laccase, and lignin-peroxidase-like enzyme. In addition, data were obtained which show that bacteria contained in the lignite are able of lignite solubilisation and utilisation.
