- No culturing required
Gary Andersen and Eric Dubinsky at Berkeley Lab have developed a technology for more precisely analyzing environmental contamination in coastal waters by determining the signature microbial communities of known fecal sources, such as birds, grazers, or sewage.
Targeting the whole microbial community for source identification is a fundamentally different approach that overcomes the shortcomings of traditional fecal indicator bacteria (FIB) monitoring—which cannot, with precision, distinguish between anthropogenic, wildlife, and non-fecal sources—as well as molecular source tracking that relies on single phenotypic or genotypic biomarkers that cannot uniquely identify one type of waste. This innovative method for determining the distinctive census of microbes in a microbial community is perfectly suited for studying the dynamics of microbial community structure under changing environmental conditions.
