Bacterial communities in district heating (DH) systems were investigated for corrosion links. While specific microbial groups weren't definitively tied to corrosion, several bacteria, including sulfate-reducing prokaryotes, may contribute to biocorrosion in DH piping.

Area of Science:

  • Microbiology
  • Corrosion Science
  • Environmental Engineering

Background:

  • District heating (DH) systems are susceptible to corrosion, impacting infrastructure integrity.
  • Understanding the microbial communities within DH systems is crucial for identifying potential biocorrosion agents.
  • Previous studies have not definitively linked specific microorganisms to corrosion in these environments.

Purpose of the Study:

  • To investigate the bacterial diversity and activity in DH systems with and without corrosion.
  • To determine if specific microbial groups can be correlated with observed corrosion phenomena.
  • To identify potential bacterial contributors to biocorrosion in DH system piping.

Main Methods:

  • Culture-independent molecular techniques, including fluorescence in situ hybridization (FISH) with oligonucleotide probes.

  • Analysis of a clone library for bacterial identification and phylogenetic placement.
  • Microautoradiography to determine functional groups of bacteria (aerobic, anaerobic, sulfate-reducing, methanogenic).
  • Corrosion studies to compare general and pitting corrosion rates.

    • Main Results:

    • Dominance of beta-proteobacteria, sulfate-reducing prokaryotes, and alpha-proteobacteria was observed.
    • Clone library analysis revealed significant sequences affiliated with Rhizobiaceae, Acetobacteraceae, and Comamonadaceae families.
    • Pitting corrosion rates were 5-10 times higher than general corrosion rates, indicating biocorrosion.
    • Functional analysis identified both aerobic and anaerobic bacteria, including sulfate-reducing and methanogenic types.

    Conclusions:

    • No single microbial group was definitively linked to corrosion, but multiple bacterial groups are implicated.
    • Sulfate-reducing prokaryotes, Acidovorax, and methanogenic bacteria are potential contributors to DH system biocorrosion.
    • Further research is needed to elucidate the specific roles of these diverse microbial communities in DH system corrosion.
