Abstract: Herein are described 1058 different bacterial taxa that were unique to either human, grazing mammal, or bird fecal wastes. These identified taxa can serve as specific identifier taxa for these sources in environmental waters. Two field tests in marine waters demonstrate the capacity of phylogenetic microarray analysis to track multiple sources with one test.

Abstract: The present invention discloses methods and systems for designing and using organism-specific and/or operational taxon unit (OTU)-specific probes. The methods and systems allow for detecting, identifying and quantitating a plurality of biomolecules or microorganisms in a sample based on the hybridization or binding of target molecules in the sample with the probes. Some embodiments provide methods of selecting an oligonucleotide probe specific for a node on a clustering tree. Other embodiments provide methods of selecting organism-specific or OTU-specific oligonucleotide probes for use in accurately detecting a plurality of organisms in a sample with high confidence. Some embodiments provide methods and systems to detect the presence of a rare OTU in a sample.

Abstract: The present embodiments relate to an array system for detecting and identifying biomolecules and organisms. More specifically, the present embodiments relate to an array system comprising a microarray configured to simultaneously detect a plurality of organisms in a sample at a high confidence level.

Abstract: Herein is described methods for a high-sensitivity means to measure the incorporation of stable isotope labeled substrates into RNA following stable isotope probing experiments (SIP). RNA is hybridized to a set of probes such as phylogenetic microarrays and isotope incorporation is quantified such as by secondary ion mass spectrometer imaging (NanoSIMS).
