Identify performance improvement opportunities for your biogas anaerobic digester.
Anaerobic digesters are employed in wastewater and landfill systems worldwide to create renewable energy. This study will analyze the microbiome and operating performance of biogas anaerobic digesters. The purpose is to identify performance improvement opportunities resulting in greater energy production at a lower overall operational cost. Target industry sectors include municipal, industrial, food processing, agricultural and landfills.
Next generation DNA sequencing and a specialized environmental microbiological database will be applied to identify nearly 100% of bacteria and archaea in each digester sample. This will enable a community analysis to identify and quantify fermenters (including acetogens), syntrophs, acetoclastic methogens and hydrogenoclastic methanogens as well as sulfate reducing bacteria and how they change over time. Archaeal and bacterial community data will be analyzed to inform makeup of the mixed community. This type of diagnostic insight is not possible with conventional testing methods such as microscopy, culture or qPCR.
The general guidance to participants, is to collect three samples for each digester and complete an operational data survey. Further guidance is forthcoming from the technical team commissioned for this study, in regards to recommended sample locations, timing of samples, and other related information. More than three samples may be collected and included in the study, particularly for the larger systems. Contact firstname.lastname@example.org and/or any of the supporting organizations listed above, to begin a dialogue on how to implement this study at your facility.
Untapped U.S. biogas opportunities have the potential to power 7.5 million American homes, while removing the equivalent of up to 15.4 million passenger vehicles from the road. The U.S. has over 2,200 sites producing biogas in all 50 states. About 13,500 new sites are ripe for development. Source: American Biogas Council.
Key findings will be presented at the Microbiome Water Summit

“I am really looking forward to learning the results of the Anaerobic Digester studies,” said Jeremy Cramer, Senior Process Engineer, Donohue & Associates. “With specialized DNA sequencing such as what is being applied in these studies, the resource recovery industry finally has the opportunity to measure the microbiology much more comprehensively than what has been previously possible. The studies will help the industry interpret results and use this new insight to optimize systems. I believe this will be a game-changer for the industry.”

Frequently Asked Questions
What is an anaerobic digester?
Anaerobic digestion involves naturally occurring methanogen bacteria that break down organic biodegradable material and convert it into methane gas, carbon dioxide and lesser amounts of other gases. These gases are referred to collectively as biogas. This “renewable biogas” serves as a substitute for fossil fuel natural gas to make clean electricity and other beneficial energy use applications.
What is the role of microbes?
For an anaerobic digester to perform properly, microscopic bacteria must survive and constantly regenerate inside the digester. The bacteria require proper organic feedstock, environmental conditions, nutrients and water to perform their functions properly and create a thriving environment. If the conditions are not optimal, the biogas production system can be significantly negatively affected or completely halted.
How will this study identify new insights?
The next generation DNA sequencing and specialized database applied in this study will be able to identify nearly 100% of bacteria and archaea in each digester sample. This will enable an archaeal community analysis to see what methanogens are present and how they change over the time of the study. We will also weight archaeal community and bacterial community data to inform makeup of the mixed community. Operational data will be compared to microbiological data to establish key performance indicators. Participants of this study will have an opportunity to learn how their digester performance compares to other digesters included in the study.
If I participate, will my company name be disclosed in the report?
No. Since this report will be shared with all participants, and will eventully enter the public domain, we will not disclose the identify of participants. Exceptions will be made for participants that wish to disclose their identify. We will evaluate this on a case by case basis. Participants will be able to identify the sample data from their digester(s) based on the unique ID of each sample.
