Different Drinking Water Sources: How Do They Affect Feces Microbiota Diversity

Fecal Microbiota

Schematic of sample preparation for 16S rRNA sequencing. Mice feces were cultured using brain heart infusion broth with four types of water in both aerobic (A) and anaerobic (N) conditions. Four water types included mineral water (MW), natural water (NW), pure water (PW) and tap water (TW). Microbial samples were collected on days 1 and 5 respectively.

News Release, International Society of Microbiota – March 10, 2022.

The human gut harbors trillions of microbes, which are extremely important to the health of the host. However, the effect of drinking water on gut microbiota has been poorly understood.

This Interesting research explored the response of BALB/c mice gut bacterial community (feces) to the different types of drinking water

  • Commercial bottled mineral water (MW)
  • Natural water (NW)
  • Purified water (PW)
  • Tap water (TW)

Interestinlgy, 16S rRNA gene analysis of collected feces revealed that

  • The gut microbiota composition was different by culturing with different types of drinking water
  • Mineral water leads to a progressive increase of the microbiota diversity and provides the growth convenience to Bacteroidetes

You can attend a session in which Prof. Nicolas Branich will talk more about the relation between water and microbiota.

The Targeting Microbiota 2022 Congress will host all these sessions in October, in France.
