Heterotrophic Aerobic Bacteria BART™ Biodetector


Often you need to test water for the presence of bacteria without trying to determine the particular groups of bacteria that may be present. When total aerobic bacteria are present and active, the blue dye in the BART bleaches either from the bottom up or the top down.

The test measure the ability of the total aerobic bacteria to respire while degrading the various nutrients in the dehydrated culture medium. Methylene blue, the dye, acts as an alternative to oxygen for microbial respiration. When the microbes respire, the methylene blue changes to a colorless form. The faster the dye is bleached, the greater the level of respiration and the larger or more aggressive the total aerobic bacteria population.

Aerobic bacteria can cause several problems in water, including slime formations, turbidity, taste and odor, corrosion, health risks, and hygiene risks. When a problem is detected, you may want to conduct more testing to determine precisely the nature of the microbial problem. You can use other BARTs to detect several types of bacteria.

The BART tester requires no microscope, no laboratory, no incubator! The test is done at room temperature in your office or treatment room, on a desk, shelf, or in a cupboard and is viewed daily. Different microorganisms like to grow at various heights in a column of water to which nutrients have been added. BART testers contain nutrients in the base of the column and a ball. The ball restricts the amount of oxygen entering the water column so that aerobic organisms grow around the ball and anerobic organisms grow deep down in the water column. By changing the nutrients in the base of the column different organisms can be encouraged to grow. BART determines presence and activity levels.

Each individual test consists of: Test vial with media and BART ball. One color chart is included in each box of 15 testers.


There are two versions of BART Testers; Field and Lab. We carry Both. The Lab BARTs are designed for laboratories and have only the inner tube that contains the media and ball. Lab BARTs are individually packaged in aluminum foil pouches and have a 4 year shelf.
