摘要：
The fatty acid composition of total lipids in two species of sponges (Halichondria panicea and Clathria pennata) inhabiting the same biotope in the Sea of Japan was examined. More than 80 fatty acids (FAs) were found for each species of sponges. Of them, 61 fatty acids were identified for H. panicea and 54 for C. pennata. The relative content of most FAs was less than 1%. The contribution of symbiotic microorganisms to the total fatty acids was higher in H. panicea than in C. pennata. Bacterial symbionts and microeukaryotes were found among the microorganisms associated with the sponges. The contribution of prokaryotic organisms was equal (7.8%) for both species of sponges, but the fatty acids were characteristic of different taxonomic groups of bacteria. The proportion of microeukaryotic fatty acids in the total lipids of H, panicea (19.6%) was two times that of C. pennata (10.1%).
