International conference “Galaxies in Isolation: Exploring Nature vs. Nurture” held in Granada (Spain), May 12–15, 2009.Low LFIR Isolated Galaxies (IGs) from the AMIGA sample have
low level of Star Formation (SF) activity. We observed the HCN(1-0) emission
in a sample of IGs in order to test whether they follow the tight relation between
LHCN and LFIR found for galaxies with more active SF
