The Overlooked Importance of Calibrating Your Enzyme
One of the major benefits of LuminUltra’s 2nd generation ATP monitoring over existing technology (i.e. ATP pens) is the normalization of enzyme activity. At the microbiological level, knowing how active the enzyme is at the time of testing offers significant benefits for both data collection and analysis. Given this, LuminUltra’s 2nd Generation ATP test… Read More
Most Wanted Microbes – Methanogens
From the editor: This is the thirteenth post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic. Methanogens are a group of microbes that produce methane gas through the breakdown of… Read More

Amazing Water Resources
If you find it easiest to understand a new concept through some type of visualization, you’re not alone. If you happen to be a ‘visual’ person and have an interest in water, there are a ton of great resources available online that can bring out the map-geek and marine biologist in anyone. Here at… Read More
Most Wanted Microbes – Candidatus Accumulibacter
From the editor: This is the eleventh post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic. Candidatus Accumulibacter is a phosphorus accumulating organism (PAOs), meaning it can store copious quantities of phosphorus under specific conditions in a process referred to as enhanced biological phosphorus removal. Systems that select for Candidatus… Read More
Am I Missing Something? A Look into the Dangers of Viable but Nonculturable Cells (VBNC)
“I’ve performed the plate count… but what am I missing?” For over a century, lab technicians for water treatment facilities have turned to culturable plate counts as their main weapon in quantifying the bacterial count for a system. What may come as a shock to these facilities is that even after a treatment has… Read More
Most Wanted Microbes – Iron Reducing Bacteria (IRB)
While sulfate reducing bacteria (SRB) are widely known as a major cause of MIC in carbon steel, other bacteria with different physiological properties have been identified as potential contributors in the corrosion process as well. Iron reducing bacteria (IRB), for example, are heterotrophic facultative anaerobes which reduce ferric ions to ferrous ions under anaerobic… Read More
No Grey Area to This Issue: Slimes of All Colours Can Cause Costly Problems in Papermaking Processes
Pink, orange, red, brown and grey – paper mill slimes can come in an endless range of colours. What contributes to these variances in colour? Microorganisms. Different species – which live within a slime – produce different hues. Unfortunately, you won’t find gold at the end of that rainbow. In fact, it’s quite the… Read More
How Can You Quickly Implement ATP Monitoring in Your Drinking Water System?
From the editor: You’ve likely heard of ATP technology, but may not have had the time to fully explore the value it can bring to your existing microbial monitoring program. Here’s a brief overview on how you can utilize ATP testing to identify and mitigate microbiological issues in your drinking water treatment and distribution… Read More
