Microbial-Community Analysis-An Automated System

Article excerpt

Microorganisms are typically the first organisms to react to chemical and physical changes in the environment. Because microorganisms are at the bottom of the food chain, changes in microbial communities are often precursors to changes in the health and viability of the environment as a whole.

Biolog, Inc., has developed an automated system for fingerprinting and tracking mixed cultures of microbes from a variety of environmental samples. Release 4.01C MicroStation[TM] and MicroLog 3E allow laboratory technicians to easily perform microbial ecological analysis on soil, water, and other samples. When the MicroLog Systems are used in conjunction with the Biolog GN, Eco, and MT MicroPlates[TM] microbial-community analysis and ecological studies can be performed on virtually any environmental sample.

Biolog MicroPlates monitor cell respiration: When a cell can use a nutrient present in one of the 96 wells of the MicroPlate, the organism will begin to respire, creating a by-product that oxidizes a tetrazolium dye used in Biolog's patented redox chemistry. The microbes will create characteristic patterns in the wells of the MicroPlate. …
