Effect of iron and dissolved silica on primmorphs of Petrosia ficiformis (Poiret, 1789)

The suitability of the primmorphs system as a good model for biotechnological applications led researchers on primmorphs to look for a medium to stimulate cell proliferation and therefore growth of aggregates. Recent efforts have focused on the use of Fe⁺³ and Si that, supplemented to cell culture medium, were found to be promising for growth and morphogenesis of the sponge Suberites domuncula. In this work, we analysed the effect of iron and dissolved silica on primmorphs of Petrosia ficiformis, by testing them at different concentrations in successive experiments. The purpose of these experiments was to test their effect on primmorphs and individuate their optimal concentration for this species. Our results suggest a negative effect of iron on primmorphs of P. ficiformis and a positive effect of silica on primmorphs size and spiculogenesis at a concentration of 120 μM.
