Humicola lutea 103 is a copper-tolerant fungal strain able to grow in the presence of 300 μg·mL–1Cu2+under submerged cultivation. To prevent the consequences of copper overload, microorganisms have evolved molecular mechanisms that regulate its u

In the present study, we examined the adaptive response of the filamentous fungus Humicola lutea 103 to copper stress. Our findings indicate that pretreatment with low concentrations of copper ions led to the development of resistance to high concent
