Radioactive contamination resulting from major nuclear accidents presents harsh environmental conditions. Inside the Chernobyl exclusion zone, even more than 30 years after the accident, the resulting contamination levels still does not allow land-use or human dwellings. To study the potential of basidiomycete fungi to survive the conditions, a field trial was set up 5 km south-south-west of the destroyed reactor unit. A model basidiomycete, the lignicolous fungus Schizophyllum commune, was inoculated and survival in the soil could be verified. Indeed, one year after inoculation, the fungus was still observed using DNA-dependent techniques. Growth led to spread at a high rate, with approximately 8 mm per day. This shows that also white-rot basidiomycetes can survive the harsh conditions in soil inside the Chernobyl exclusion zone. The unadapted fungal strain showed the ability to grow and thrive in the contaminated soil where both stress from radiation and heavy metals were present.

切尔诺贝利禁区恶劣环境条件下土壤中担子菌裂褶菌群落的生存

重大核事故造成的放射性污染带来了恶劣的环境条件。在切尔诺贝利禁区内,即使在事故发生 30 多年后,由此产生的污染水平仍然不允许土地使用或人类住宅。为了研究担子菌真菌在这些条件下生存的潜力,在被毁坏的反应堆单元西南偏南 5 公里处进行了现场试验。一种模型担子菌,木质真菌Schizophyllum commune, 被接种并且可以验证在土壤中的存活。事实上,接种一年后,仍使用 DNA 依赖技术观察到真菌。生长导致快速扩散,每天大约 8 毫米。这表明白腐担子菌也可以在切尔诺贝利禁区内土壤的恶劣条件下生存。未适应的真菌菌株显示出在存在辐射和重金属压力的受污染土壤中生长和繁殖的能力。
