AMD - DIF Record(s) USAP-1644155_1 Abstract Varying depth samples from Ace, Deep, & Organic Lake were obtained between 2013-2014. These samples were size fractionated by filtration for metagenomic analyses. Viral and bacterial abundances were determine on the filtrate fractions by flow cytometric analysis. Glutaraldehyde-fixed samples were stained with SYBR Green I fluorescence dye and virus-like particle (VLP) and bacteria-like cell (BLC) populations were discriminated based on green fluorescence and side scatter flow cytometry signals.
