Embodiment Construction

[0029] The principles and features of the present invention are described below in conjunction with examples, which are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0030] 1. Obtaining Anabaena AS-182

[0031] Anabaena AS-182 (Anabaena sp.182) of the present invention is obtained by isolating algae-containing water samples collected from field paddy fields, and its cell morphology is as follows: figure 1 As shown, the microalgae belonged to the genus Anabaena after morphological and physiological identification. The microalgae has been preserved in China Center for Type Culture Collection (CCTCC) of Wuhan University, Wuhan City, Hubei Province, China on October 31, 2017. The preservation number is CCTCC NO: M 2017644, named Anabaena AS-182, Latin The scientific name is Anabaena sp.AS-182.

Abstract

The invention relates to anabaena. The anabaena is preserved in CCTCC (China Center for Type Culture Collection) with preservation number being CCTCC NO:M 2017644 on 31st, October, 2017. The inventionfurther relates to an application of the anabaena in removal of Cd in the environment and a method for removing Cd in the environment. The anabaena can efficiently adsorb Cd<2+> in a water body, so that the anabaena can be used for treating the water body with high Cd<2+> content to remove Cd<2+> in the water body and reduce Cd pollution; the anabaena particularly can be used for controlling Cd pollution of rice irrigation water, and accordingly, Cd content of rice is reduced.

Description

technical field [0001] The invention relates to the field of environmental biotechnology, and more particularly relates to an anabaena capable of removing cadmium in the environment and its application, as well as a method for removing cadmium in the environment. Background technique [0002] Due to the rapid development of modern industry, heavy metal mining, smelting, processing and other production activities cause a large amount of heavy metals to enter the environment, including water, soil and air. Industrial sewage, domestic wastewater, etc. are discharged into rivers without proper treatment, and domestic garbage leachate seeps into groundwater and diffuses with the runoff of water and the flow of sediment, causing serious heavy metal water pollution. Among them, heavy metal pollution in agricultural water or aquaculture water has a more direct threat to human health due to bioaccumulation. [0003] The heavy metal pollution of agricultural water mainly comes from t...
