英文摘要	The application of cyanobacteria to create biocrusts has gained attention for combating desertification and improving agricultural soil fertility. However, there is limited information available regarding the use of cyanobacteria in mine tailings to enhance their biophysicochemical properties. Identifying suitable inoculants that can effectively establish biocrusts in challenging mine tailings environments is an imperative aspect that requires investigation. This study investigated the performance of two nitrogen-fixing cyanobacteria, Anabaena sp. and Nostoc muscorum, both individually and as a consortium, in the formation of biocrusts on gold mine tailings under sterile and non-sterile conditions. The findings demonstrated that the consortium inoculation of cyanobacteria successfully created stable biocrusts, leading to a significant reduction in wind erosion (0.85% vs. 81.99% mass loss), an increase in compressive strength (1.90 vs. 0.1 kg cm(-2)), and improvements in organic carbon (17.23 vs. 3.26 mg g(-1) tailings) and nitrogen (3.89 vs. 0.036 mg g(-1) tailings) compared to the water-treated tailings. There were variations in the effectiveness of the two cyanobacteria in enhancing the biophysicochemical properties of the tailings. Anabaena sp. promoted higher synthesis of chlorophyll-a, EPS, organic carbon, and nitrogen compared to N. muscorum, thus enhancing fertility of the tailings. Conversely, N. muscorum contributed to the formation of a more wind-resistant structure. Through consortium inoculation of the cyanobacteria, the beneficial effects observed with the individual strains could be combined, leading to a comparatively more resilient structure. The results also indicated that the presence of the indigenous microbiota in the tailings influenced the performance of the cyanobacteria depending on the inoculant used. Overall, biocrust formation by the consortium of Anabaena sp. and N. muscorum can be beneficially employed as an environmentally sustainable method for gold mine tailings stabilization. [Graphics] .
