Candidatus “Brocadia Sinica” JPN1
Tomorrow Water’s Unique Anammox Species: Candidatus “Brocadia Sinica” JPN1
Considered to be one of the best Anammox strains, Candidatus “Brocadia Sinica” JPN1, demonstrates excellent growth rates in both high and low substrate conditions and maintains its activity even at high salt concentrations. It achieves 2x higher growth rates and has higher salinity resistance (up to 3%) compared to other Anammox strains.
Physiological Characteristics:
-
Wider operational window, especially suited for warmer climates or thermally controlled reactors.
-
Offers more flexibility in pH control, which simplifies process operation and reduces chemical dosing needs.
-
Faster than other species like B. anammoxidans and K. stuttgartiensis, supporting quicker reactor startup and recovery.
-
Means biomass accumulates faster, which is beneficial for system startup and achieving stable performance.
-
Balanced biomass production helps in managing sludge yield and retention.
-
While high Kₘ usually means lower affinity, B. sinica seems capable of handling high substrate concentrations, particularly nitrite (Kₘ for NO₂⁻ = 86 ± 4 µM), suggesting better performance under higher nitrite loads, as seen in your pilot data.
-
Makes B. sinica ideal for systems with variable or elevated nitrite concentrations, reducing risk of inhibition.
-
Can survive low levels of oxygen intrusion, which is advantageous in full-scale systems where perfect anoxic conditions are hard to maintain.
-
Provides robustness in saline or variable salinity wastewater, such as landfill leachate or industrial.
