SYNGAS BIOMETHANATION ENHANCEMENT VIA BIOAUGMENTATION TECHNOLOGY

Publisher

Supervisor

Location

Greater Copenhagen area

Background

The syngas fermentation gained much attention and interests for its potential to produce biofules, such as methane, and biochemicals from syngas (mainly CO, CO2 and H2 from gasification of biomass) and CO-rich waste gas streams. Syngas biomethanation is particularly attractive because it can be integrated into the existing biogas facilities to save installation cost. Therefore, it is necessary and meaningful to investigate the mechanisms of the microbial driven syngas conversion and control the process for further commercial application.

Especially, the CO conversion is one most important part during syngas biomethanation because CO is not only a toxin to many microbes but also can be used as carbon source for a specific group. It was reported the bioaugmentation technology is a useful method to enhance the anaerobic digestion process. In addition, the pathway of CO in syngas may also be adjusted by bioaugmentation to attain better performance. Therefore, it is necessary and meaningful to investigate the bioaugmentation technology for the microbial driven syngas conversion and efficiency enhancement.

Project description:

The special project aims at investigating impact of bioaugmentation addition on syngas biomethanation. All the work is carried out at DTU (Lyngby campus). The main tasks of the special project are as following:

1)      Operate batch experiments for syngas biomethanation with different carbon sources.

2)      Different bioaugmentation will be added during syngas biomethanation to investigate their impacts on syngas conversion.

3)      Analysis special CO conversion pathway and microbial diversity.

Approach

    Bath experiments will be applied to operate the experiments, and gas chromatography (GC) is used to analyze the VFAs component in liquid samples and gas composition. The microbial community under different conditions are analyzed via high-throughput 16S rRNA pyrosequencing.

Requirements

Own background with environmental engineering or chemical and biochemical engineering or biotechnology knowledge.
