Morel is a popular edible mushroom with considerable medicinal and economic value which has garnered global popularity. However, the increasing heavy metal (HM) pollution in the soil presents a significant challenge to morels cultivation. Given the susceptibility of morels to HM accumulation, the quality and output of morels are at risk, posing a serious food safety concern that hinders the development of the morel industry. Nonetheless, research on the mechanism of HM enrichment and mitigation strategies in morel remains scarce. The morel, being cultivated in soil, shows a positive correlation between HM content in its fruiting body and the HM content in the soil. Therefore, soil remediation emerges as the most practical and effective approach to tackle HM pollution. Compared to physical and chemical remediation, bioremediation is a low-cost and eco-friendly approach that poses minimal threats to soil composition and structure. HMs easily enriched during morels cultivation were examined, including Cd, Cu, Hg, and Pb, and we assessed soil passivation technology, microbial remediation, strain screening and cultivation, and agronomic measures as potential approaches for HM pollution prevention. The current review underscores the importance of establishing a comprehensive system for preventing HM pollution in morels.
羊肚菌是一种广受欢迎的可食用蘑菇，具有相当大的药用和经济价值，在全球都很受欢迎。然而，土壤中日益严重的重金属污染对羊肚菌的种植构成了重大挑战。鉴于羊肚菌对重金属积累的敏感性，羊肚菌的品质和产量面临风险，引发了严重的食品安全问题，阻碍了羊肚菌产业的发展。尽管如此，关于羊肚菌中重金属富集机制和缓解策略的研究仍然很少。羊肚菌生长在土壤中，其子实体中的重金属含量与土壤中的重金属含量呈正相关。因此，土壤修复成为解决重金属污染最实际、最有效的方法。与物理和化学修复相比，生物修复是一种低成本、环保的方法，对土壤成分和结构的威胁最小。研究了羊肚菌种植过程中容易富集的重金属，包括镉、铜、汞和铅，并评估了土壤钝化技术、微生物修复、菌株筛选和培养以及农艺措施作为预防重金属污染的潜在方法。本综述强调了建立一个全面的羊肚菌重金属污染预防体系的重要性。
