Uncovering the role of algal organic matter biocoating on cell deposition and biofilm formation.

Spontaneous natural biofilm concentrates microalgal biomass on solid supports. However, the biofilm is frequently susceptible to exfoliation upon nutrient deficiency, particularly found in aged biofilm. Therefore, this study highlights a novel biofilm cultivation technique by pre-depositing the algal organic matters from marine diatom, onto microporous polyvinylidene fluoride membrane to further strengthen the biofilm developed.
