Trichoderma atroviride isolated from mangroves of the east coast of Peninsular Malaysia exhibited high tolerance against heavy metal cadmium

The toxicity of the heavy metal cadmium to organisms is known, with differing tolerance in different organisms. The ability of fungi to survive in sites polluted with heavy metals has led to its mechanism of heavy metal tolerance being widely investigated. However, little work has addressed cadmiu...
