Abstract
The present invention discloses a microcapsule material capable of reducing pollution containing polycyclic aromatic hydrocarbons, and a preparation method and application thereof. The preparation method comprises the following steps: (1) culturing mycobacterium gilvum CP 13 in a bacteria culture liquid to obtain a bacterial broth, wherein the mycobacterium gilvum CP 13 was deposited in China General Microbiological Culture Collection Center (CGMCC) on Jul. 22, 2013 with a CGMCC number of CGMCC No. 7963; and (2) applying a calcium alginate and chitosan to encapsulate the bacterial broth in a microcapsule through layer-by-layer self-assembly to produce a microcapsule material capable of reducing pollution containing polycyclic aromatic hydrocarbons. The present invention produces a microcapsule material with the microorganic activity through layer-by-layer self-assembly, which has superior adaptability to the environment and good ability to reduce pollution containing polycyclic aromatic hydrocarbons. The microcapsule material of the present invention can be used in bioremediation of industrial wastewater containing polycyclic aromatic hydrocarbons and contaminated soil containing p…
