Effect of water velocity on the early development of manganese‐depositing biofilm in a drinking‐water distribution system

A study of the development of biofilm colonizing the surfaces of pipes in a drinking‐water distribution system has shown that water velocity significantly influenced the nature and physiological activity of the biofilm. Biofilm developed at a velocity of 0.5 m s−1 actively oxidized and deposited man...

Description
Summary:A study of the development of biofilm colonizing the surfaces of pipes in a drinking‐water distribution system has shown that water velocity significantly influenced the nature and physiological activity of the biofilm. Biofilm developed at a velocity of 0.5 m s−1 actively oxidized and deposited manganese, but at 0.01 m s−1 no manganese was deposited. Budding bacteria were the dominant microorganisms depositing manganese but a variety of other organisms were also present in the biofilms. The budding bacteria oxidizing manganese were Pedomicrobium manganicum and Metallogenium.
