Strain-specific necromass enrichment of sediment bacterial communities
Fed necromass (bacterial lysate) at 30 ppm C from three separate bacterial strains (Pseudomonas, Arthrobacter, or Agrobacterium, or mix of all three) to a sediment community from the Oak Ridge Reservation in Tennessee, USA over a 14-day incubation inoculated in 20 mL synthetic groundwater media. Samples were conducted in replicate, and sampled for DNA extraction in 1 mL aliquots. Samples were repeatedly taken at time0, then days 2, 4, 6, and 14.
