Title:
BACILLUS SP. FOR PRODUCING BIOFLOCCULANT AND BIOSURFACTANT, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/261820
Kind Code:
A1
Abstract:
Provided is a SS15 strain of a Bacillus sp. for producing a bioflocculant and a biosurfactant, with the deposit number thereof being CCTCC M 2021295. The 16S rRNA sequence of the strain is as shown in SEQ ID NO: 1. The strain can be used in the remediation of fracturing outlet liquids, and can also effectively promote the removal of chromaticity, suspended solids, COD, n-alkanes and polycyclic aromatic hydrocarbons.
