Performance problems with dairy farm anaerobic digester linked to overly dominant Fungi

Performance problems with dairy farm anaerobic digester linked to overly dominant Fungi

Performance problems with dairy farm anaerobic digester linked to overly dominant FungiBiogas production from anaerobic digestion of organic waste is a biotechnological process involving complex bacterial, archaeal and likely fungal communities. The presence and function of active fungi in anaerobic digesters have been barely investigated (1). In this project, Aspergillus fungi were observed at a surprisingly dominant abundance in a Jersey cow dairy farm anaerobic digestion process that had...

Are biofilms secretly lurking in your cooling water systems?

Are biofilms secretly lurking in your cooling water systems?Water has excellent heat transfer efficiency, which is the driving force behind medium to large commercial and manufacturing facilities' preference for water-cooled systems over their air-cooled counterparts. Ensuring optimal ambient air temperatures for guest comfort and precise process temperature control, water-cooled systems play a crucial role in various industries.  Microbiological fouling is an ongoing concern in open...

Fecal contamination observed near wastewater plant along Florida’s coast was from non-human sources

Fecal contamination observed near wastewater plant along Florida’s coast was from non-human sources

Fecal contamination observed near wastewater plant along Florida's coast was from non-human sourcesA municipal wastewater treatment plant (City WWTP) fielded complaints regarding fecal matter on local beaches. In review of the potential sources of fecal contamination with Microbe Detectives (MD), and MD technical advisor Alison Ling, PhD, three had been contemplated including animal feces, human feces from the City’s homeless population, and the City WWTP.  The objectives of this sampling and...

Insights to major upset at wastewater plant revealed

Insights to major upset at wastewater treatment plant revealedA 10 MGD municipal wastewater treatment plant in the southwest US experienced a major plant upset and called Microbe Detectives to help diagnose the problem. Three Mixed Liquor Suspended Solids (MLSS) samples were collected from the aeration basin and were analyzed using 16S and 18S rRNA sequencing methodology, identifying all Bacteria, Archaea, and Eukarya present in the sample and the % relative abundance of each. Problem #1 -...

Septic contamination discovered in pressurized toilet system in residential apartment building

Septic contamination discovered in pressurized toilet system in residential apartment building A resident of an apartment building complex contacted Microbe Detectives in the spring of 2023 to see if the potable water supplied to his apartment could be analyzed for microbiological contamination. He had a persistent cough at the time and wanted to know if the problem could be with the water.The water source was a sample of the building’s pressured toilet system. The water, even from a clean...

Iron bacteria and biofilms wreak havoc on stainless steel potable water system

Iron bacteria and biofilms wreak havoc on stainless steel potable water system

Iron bacteria and biofilms wreak havoc on stainless steel potable water distribution system in 6 monthsPitting corrosion at the welds of a stainless steel potable water service line(s) at a large dairy farm had occurred within six months of commenced operation. Microbe Detectives was hired to analyze water samples from this system and assess the likelihood of Microbiologically Influenced Corrosion (MIC). Four water samples were analyzed using DNA amplicon sequencing of the 16S and 18S rRNA...

The Facultative Membrane BioReactor (FMBR)

The Facultative Membrane BioReactor (FMBR)

The Facultative Membrane BioReactor (FMBR) The FMBR is a one-step, single tank solution for on-site wastewater collection, treatment and reclaimed water, suitable for commercial and residential areas, watershed pollution protection, and wastewater treatment plant upgrading. Compared to traditional sequencing batch reactors (SBR) and MBR systems, it operates with low energy and a small footprint. These design characteristics make for an efficient Decentralized Wastewater Treatment System...

Enhance anaerobic digester efficiency with DNA sequencing

Enhance anaerobic digester efficiency with DNA sequencing

Enhance the efficiency of anaerobic digesters with next-gen DNA sequencingAnaerobic digesters are employed in wastewater, landfill and livestock operations worldwide to create renewable energy. Improving biogas production in a one-million gallon reactor by 5-10% can offset up to $200,000 annually in power costs when used for onsite power (Ling, A. 2020). This study used 60 samples from 21 digesters representing a variety of industries, feedstocks, reactor design, and operational conditions....
