Abstract

The invention provides anabaena sp. PD-3 capable of efficiently degrading polychlorinated biphenyl (PCB), and application thereof to microbiological degradation of polychlorinated biphenyl. The anabaena sp. PD-3 is collected in the China Center For Type Culture Collection, with an address of Wuhan universality, Wuhan, China, a postal code of 430072, a collection date of September 8, 2013, and a collection number of CCTCC No.M2013398. The invention provides anabaena PD-3 capable of efficiently degrading polychlorinated biphenyl. The anabaena is capable of effectively degrading PCB28, 29, 30 and 31; after the exposure for a week, the degradation efficiency of the anabaena to PCB28 exceeds 60 percent, the dechlorinating percents of the anabaena to PCB44 and PCB61 are respectively 63.6 percent and 57.3 percent, and are superior to those (49.3 percent and 48.3 percent) of anabaena PD-1 (with a collection number of CCTCC No: M2011446). Thus, the anabaena PD-3 can be widely applied to the degradation of polychlorinated biphenyl in the environment, and has an important application prospect.

Description

technical field

[0001] The invention relates to an Anabaena sp. PD-3 capable of efficiently degrading polychlorinated biphenyls and its application in microbial degradation of polychlorinated biphenyls. Background technique

[0002] Polychlorinated biphenyls (PCBs), as an organic material with good chemical and thermal stability, have been widely used in industrial production fields. PCBs have obvious "three-induced" effects and strong fat solubility, and can accumulate and accumulate in organisms along the food chain, causing harm to organisms. Although its production and use were banned in 1979, due to its half-life of about 40 years, it has significant environmental persistence, and the semi-volatility of PCBs also makes it migrate around the world with atmospheric dry and wet deposition and eventually deposit in surface. Therefore, PCBs are commonly detected in polluted and non-polluted soils around the world. PCBs remaining in the environment have serious potential r...
