Detection of Viable Organisms Using Molecular Techniques
from Paul A. Rochelle, Anne K. Camper, Andreas Nocker and Mark Burr in Environmental Microbiology: Current Technology and Water Applications
The ultimate measure of microbial viability and biological activity is growth in some form of culture system. Unfortunately, due to many limitations, growth is usually not the most sensitive or rapid detection method. Many molecular-based tools are available for assessing viability and functional gene expression, and have applications for specific microbes in environmental samples. Methods include fluorescent nucleic acid binding dyes, enzymatic conversion of substrates to fluorescent compounds (often in conjunction with nucleic acid-based methods), various techniques based on amplification and detection of nucleic acids, nucleic acid amplification linked to biosensors and microarray detection platforms, detection and characterization of proteins, and molecular detection coupled with culturing.
