Abstract：
Microcystins (MCs) produced by Microcystis aeruginosa are harmful to animal and human health, and there is currently no effective method for their removal. Therefore, the development of biological approaches that inhibit cyanobacteria and remove MCs is needed. We identified strain MB1, confirmed as Morchella, using morphological and mole-cular evolution methods. To assess the impact of strain MB1 on M. aeruginosa, we conducted an experiment in which we inoculated M. aeruginosa with Morchella strain MB1. After their co-cultivation for 4 d, the inoculation with 0.9696 g MB1 completely inhibited and removed M. aeruginosa while concurrently removing up to 95% of the MC content. Moreover, within 3 d of their co-cultivation, MB1 removed more than 50% of nitrogen and phosphorus from the M. aeruginosa solution. Therefore, the development of effective biological techniques for MC removal is paramount in safeguarding both the environment and human well-being. We herein successfully isolated MB1 from its natural habitat. This strain effectively inhibited and removed M. aeruginosa and also reduced the content of nitrogen and phosphorus in the M. aeruginosa solution. Most importantly, it exhibited a robust capability to eliminate MCs. The present results offer a new method and technical reference for mitigating harmful algal blooms.
摘要：
铜绿微囊藻产生的微囊藻毒素(MCs)对动物和人体健康有害,目前没有有效的去除方法。因此,需要开发抑制蓝细菌和去除MC的生物方法。我们鉴定了MB1菌株，确认为羊肚菌，使用形态学和痣进化方法。为了评估菌株MB1对铜绿假单胞菌的影响，我们进行了一项实验，其中我们用羊肚菌MB1接种了铜绿分枝杆菌。在他们共同培养了4张后，接种0.9696ngMB1完全抑制并去除铜绿假单胞菌，同时去除高达95％的MC含量。此外，在他们共同种植的3周内，MB1从铜绿分枝杆菌溶液中去除超过50%的氮和磷。因此,开发有效的MC去除生物技术对于保护环境和人类福祉至关重要。我们在此成功地从其自然栖息地中分离出MB1。该菌株有效地抑制和去除铜绿假单胞菌，并降低铜绿假单胞菌溶液中的氮和磷含量。最重要的是,它表现出强大的消除MC的能力。本研究结果为减轻有害藻华提供了新的方法和技术参考。
