US 2025/0051713 A1 · APPLICATION OF ALKALI-TOLERANT MICROBIAL BACTERIA PDC-1 AND ITS IN-SITU REMEDIATION OF ORGANIC CONTAMINATED SOIL IN MINING AREAS

Abstract

The present invention discloses an alkali-resistant microbial bacterium PDC-1 and its application. The present invention screens and isolates PDC-1 strain from the soil of a coal gangue stockpile in a coal mine in Shandong, China, which can utilize naphthalene, phenanthrene, anthracene or pyrene as the sole carbon source and has tolerance to heavy metals. The strain of the present invention is capable to degrade various PAHs with the presence of heavy metals. The strain is alkali resistant, simple to cultivate, and has a good application in the bioremediation of polycyclic aromatic hydrocarbons and heavy metal contaminated sites.
