Chromatography explains why luminous fungi glow in the dark

When you think of organisms that glow in the dark you might think of jellyfish or fireflies, but some mushrooms glow after dark too, and now we know how. A team of international researchers from Russia, Brazil and Japan were able to identify the chemical reactions employed by fungi to make them glow and they discovered that their glow is due to a compound called oxyluciferin. The compound is ...

Feed Water Delivery System Audit Using 2 nd Gen eration ATP - Case Study

Background A Western Canadian oil producer utilized LuminUltra's Quench-Gone Aqueous (QGA) test kit to perform an audit of its feed water delivery system. The site acquired water from underground brackish water wells and transported this water through a 5 kilometer pipeline to the site. Water was then stored in a large tank prior to being sent to the process. The goal of the site audit was to ...

Influence of nutrient supplementation on DOC removal in drinking water biofilters

Analysis of the impacts of nitrogen, phosphorus and potassium supplementation on biofilter performance for organic carbon removal was studied on laboratory-scale biofilter columns. Three dual media biofilter columns were fed with synthetic raw water C:N:P ratios of 546:24:1, 100:10:1, and 25:5:1 (w/w) to simulate nutrient limited and two nutrient supplemented conditions, respectively. ...

The DNA Revolution for Water Professionals

Imagine trying to solve a problem when you are provided just 1% of the total data. This is essentially the case in analyzing water and wastewater microbiomes. Conventional microbiological testing methods such as culture and microscopy can identify only about 1% of microorganisms that are contained in a typical environmental sample. The remaining 99% are known to be there, but can not be ...

Microbe Edition: Biological Nutrient Removal How In-Pipe Technology Works

Biological Nutrient Removal (BNR) is critical for tie preservation of our lakes and streams. Large amounts of waste products are passed through our sewage treatment systems on a continuous basis. Nutrient loads discharged from these systems must be reduced to avoid eutrophication of the receiving waters. Microbes are aarticularly useful in biodegrading most of the com sounds treated by wastewater ...
