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

Most Wanted Microbes – Bacillus 

From the editor: This is the twelfth 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. Bacillus is a genus of microbes that has many positive uses in various industries such as medical care, and veterinary care,… 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

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
