Biological toilet odour control
WCzyme
WCzyme is presented as a Bacillus spp. solution aimed at converting NH₃/NH₄⁺, breaking down organic matter and limiting odour-causing microbes in damp environments.
The toilet odour problem
The ammonia smell starts with urea, NH₃ and microbes
The dossier names three main sources: ammonia and urea from urine, accumulated organic compounds, and the growth of odour-causing bacteria.
- Bacillus spp. assimilate NH₃/NH₄⁺ into odourless amino acids.
- Occupying space and competing with other microorganisms.
- Secreting protease, lipase and other natural enzymes that loosen build-up.
- Maintaining a surface microbiome so the odour does not return.
Key benefits
Biological odour control that lasts
The dossier highlights the value of regular use: safe, less risk of corroding fixtures, and environmentally friendly.
