Conversely, live cells release biomacromolecules which are key to their survival and growth; this includes lipases which microbes secrete to break down lipids so they can be absorbed. To explore the role of lipase in these transformations, cubosomes were prepared using the non -hydrolysable lipid phytantriol and incubated with microbiome strains as previously described. SAXS (Figure ) confirmed the cubic (Pn3m) liquid crystal structure, revealing no change in liquid crystal structure or lattice parameter after exposure to any bacterial strain tested.
