P/A Broth with MUG allows simultaneous detection of total coliform bacteria and E. coli. In addition to the lactose and lauryl tryptose broths with bromcresol purple, this medium contains MUG reagent (4-methylumbelliferyl-b-D-glucuronide). The MUG reagent produces a fluorogenic product when hydrolyzed by glucuronidase (an enzyme specific to E. coli). MUG detects non gasproducing (anaerogenic) strains of E. coli and works well when competitive organisms are present.
Combine 100 mL of sample and P/A Broth with MUG, incubate for 24 hours and check for a color change and fluorescence. A yellow color indicates the presence of total coliforms. To detect E. coli, examine samples under a long-wave ultraviolet (UV) light. Fluorescence indicates the presence of E. coli.

For most humans, mayflies seem like a nuisance, hovering over the waterways as we try to enjoy them. However, for anyone hoping to monitor the health of watersheds, mayflies are important aquatic species—and now, a digital version of the mayfly is helping some scientists keep an eye on the water. Research scientist Dr. Scott Ensign , who serves as Assistant Director of the Stroud Water Research Center , spoke to EM about how the digital mayfly technology developed.
“ Shannon Hicks is the engineer who started developing the Mayfly six or seven years ago,” explains Dr. Ensign.Read More
Time is of the essence when it comes to tracking algal blooms, and people everywhere are looking for solutions. In Florida, scientists from Florida Atlantic University Harbor Branch Oceanographic Institute (HBOI) recently trialed a solar-powered, algae-tracking sail boat developed by Navocean , Inc. Dr. Jordon Beckler of Florida Atlantic University (FAU) directs HBOI's Geochemistry and Geochemical Sensing Lab and spoke to EM about the trials and the boat.
"This boat is so amazing when you see it in action," remarks Dr. Beckler. "Navocean originally contacted me a few years back about a demonstration when I was over at my previous institution in West Florida, and we brainstormed some scenarios for employing the boat for harmful algae bloom monitoring.Read More
CICHAZ Biological Field Station Provides A Unique Educational and Research Experience in Mexico’s Huasteca Region
The story of the Centro de Investigaciones Científicas de las Huastecas "Aguazarca" (CICHAZ) Biological Field Station, a member of the Organization of Biological Field Stations ( OBFS ), starts with Dr. Gil Rosenthal, Professor of Biology and Chair of Ecology and Evolutionary Biology at Texas A &; M University . Rosenthal has worked in the Huasteca region of Mexico since 1994 and for years kept his research equipment at a local ranch/hotel with the dream of one day having a field station where he could run experiments with collaborators and students. Since 2005, Rosenthal has been the Co-Director of the field station along with his wife, Dr.Read More
