Bioremediation of non-point hydrogen sulfide emissions using bacterial cellulose/activated carbon membrane.

ABSTRACT:

Background

Hydrogen sulfide (H₂S) gas, characterized by its low odor threshold and toxicity, poses significant challenges in non-point source odor management. Traditional biotechnologies are effective in removing malodorous gases from point sources but they are limited for non-point source odor control.

Results

In this study, the sqr and pdo genes from Cupriavidus pinatubonensis JMP134 were introduced into the bacterial cellulose-producing strain Kosakonia oryzendophytica FY-07. This genetic modification enhanced the strain's sulfur oxidation capacity, which increased over time, with an average transformation capacity of approximately 275 mg·L^- 1·day^- 1. By incorporating 1% activated carbon, an efficient, naturally degradable bio-composite me
