Effectiveness of heat treatment to protect introduced denitrifying bacteria from eukaryotic predatory microorganisms in a pilot-scale bioreactor
Bioaugmentation of bioreactor systems with pre-cultured bacteria has proven difficult because inoculated bacteria are easily eliminated by predatory eukaryotic-microorganisms. Here, we demonstrated an intermediate thermal treatment was effective for protecting introduced denitrifying bacteria from eukaryotic predators and consequently allowed the inoculated bacteria to survive longer in a denitrification reactor.
