Delavie Sciences Bacillus Lysate

Bacillus Lysate has significant UV-shielding properties in greater ranges than current UV filters. Bacillus Lysate’s broad- spectrum technology demonstrates absorbing/blocking properties in the HEV and near IR wavelengths. As the first biological product certified by the Space Foundation, Bacillus Lysate is a safer, natural alternative to the harmful chemicals used in most sunscreens.

Effect on Skin Microbiome-Associated Bacteria

Delavie Sciences Bacillus Lysate - Effect On Skin Microbiome-Associated Bacteria

Delavie Sciences Bacillus Lysate - Effect On Skin Microbiome-Associated Bacteria - 1

Delavie Sciences Bacillus Lysate - Effect On Skin Microbiome-Associated Bacteria - 2


  • Bacterial Strains
    • A: Staphylococcus epidermidis ATCC® 35984™
    • B: Staphylococcus aureus ATCC® 25923™
    • C: Cutibacterium acnes ATCC® 6919™
  • Experimental Design
    • 4.5 mL test tubes of TSB (control) or TSB + 2% Bacillus Lysate were inoculated with bacterial culture, then incubated at 37 °C, 225 RPM and their absorbance values recorded over time.
  • Results
    • 2% Bacillus Lysate maintained the viability of the microorganisms after 15 hours of incubation. Bacillus Lysate did not inhibit the growth of skin microbiome associated bacteria; it is a microbiome- friendly ingredient.
Study Results
  • Increases broad-spectrum UV-absorbing properties of consumer products
  • Provides a safe, natural alternative to chemicals that may negatively impact human health and the environment

Delavie Sciences Bacillus Lysate - Study Results

  • Testing was conducted using a 96 well microtiter plate reader,and confirmed via third party using a Shimadzu UV-3600 UV-VIS-NIR spectrophotometer. Bacillus Lysate samples were suspended in diH2O.
  • Oxybenzone concentration is the FDA-established limit as an additive to skin care products.
