Description

technical field

[0001] The invention belongs to the field of new strain screening technology and environmental microorganism technology, and in particular relates to a heavy metal-resistant cupriavdus sp. HXC-8 and a preparation method and application thereof. Background technique

[0002] In recent years, the heavy metal pollution of soil by mining, chemical industry and life has become increasingly serious. Heavy metals cannot be decomposed by themselves in the soil, remain for a long time, cause great harm, and are easily absorbed by crops to affect human health. Copper pollution is a common heavy metal pollution. Too much copper in the soil accumulates and stays in the roots after being absorbed by plants, which hinders the roots from absorbing other components, especially iron, leading to poor plant growth. Excessive copper entering the body will cause Nausea, vomiting, epigastric pain, acute hemolysis and renal tubular deformation and other poisoning phenomena. Biore...
