Growth of Biofilm #52 in microtiter plate. A 1 mm2 biofilm (seed culture) at day 0 (a, b); in 24 h (c); 7 days (d) and 9 days (e); days 9 and 14 (f and g, respectively); (hj) growth of BAPS-52-4 and BAPS-52-5 diatoms within Biofilm #52 in F2 + Si media. (i) under UV light; (j) staining for lipids with Nile Red. Scale bars A (a, d, eg), 1 cm; A (b, c), 1 mm; A (hj), 20 µm. B Growth rates of Biofilm #52 in F2 media. Significance levels: *P < 0.05
