“…In marine ecosystems, PUFAs contribute to the structural integrity of cell membranes in phytoplankton and other marine organisms, enhancing their resilience to environmental stressors (de Carvalho & Caramujo, 2018;Hernando et al, 2022). As these PUFAs are transferred from primary producers to higher trophic levels through consumption, they exert a significant influence on the health and stability of entire marine ecosystems (Bell & Tocher, 2009).…”

Over the past few decades, due to sea warming driven by global climate change, the habitat range of round sardinella (Sardinella aurita) has expanded into the north-western Mediterranean Sea. This study evaluates the fatty acid content and fatty acid profile of this small, warm-water pelagic fish caught in this area, specifically the northern Catalan coast. The findings provide important insights into the nutritional status of the species under changing environmental conditions. The study confirms that fatty acid content varies according to the individual specimen’s maturity stages (immature, pre-spawners, and spawners). Pre-spawners showed higher fat levels compared to spawners, whose lipids are allocated to their gonads to enhance the survival of their offspring. While a high content of omega-3 polyunsaturated fatty acids (n-3 PUFAs) was generally found at all stages of maturity, pre-spawners had higher levels of EPA but lower levels of DHA than immature individuals and spawners. Moreover, compared to small pelagic fish more typical of the temperate waters in the region (European anchovy, Engraulis encrasicolus, and European sardine, Sardina pilchardus), round sardinella generally have a higher level of PUFAs, especially DHA. Encouraging consumption of this warm water species could provide significant nutritional benefits while reducing fishing pressure on European sardine and European anchovy, whose populations are currently in a very poor state.

“…Bacteria respond to various environmental cues by altering the FA composition of their lipids, including the degree of acyl chain unsaturation and length (Sinensky 1974 , Laczko-Dobos et al 2010 , Hernando et al 2022 ). For instance, an increase of unsaturated FAs in individual lipids is often related to responses to low temperature (Sakamoto and Bryant 2002 , Mikami and Murata 2003 , Sato and Wada 2009 , Guyet et al 2020 ).…”

Fatty acids are important molecules in bioenergetics and also in industry. The phylum Cyanobacteria consists of a group of prokaryotes that typically carry out oxygenic photosynthesis with water as an electron donor and use carbon dioxide as a carbon source to generate a range of biomolecules, including fatty acids. They are also able to import exogenous free fatty acids and direct them to biosynthetic pathways. Here, we review current knowledge on mechanisms and regulation of free fatty acid transport into cyanobacterial cells, their subsequent activation and use in the synthesis of fatty acid-containing biomolecules such as glycolipids and alka(e)nes, as well as recycling of free fatty acids derived from such molecules. This review also covers efforts in the engineering of such cyanobacterial fatty acid-associated pathways en route to optimized biofuel production.
