How to pulverize a deep-sea sponge? This gallery shows Master student Patryk Nilsson (Uppsala University – Division of Pharmacognosy, have a look at the sponges’ natural products group site!) on his quest to explore secondary metabolites of Geodia hentscheli (this very specimen was sampled on the Schultz Massive Seamount in the Greenland Sea). It all culminated in the last picture: on the right the beautiful yellow extraction of G. hentscheli – on the left, other Master students made the same extraction for a different yet closely related sponge species, Geodia barretti. You can already see: different color = different chemistry. However, rewind: what was the first step to get there? Reduce the sponge into a fine, dry powder! Not really an easy task…
