The cellular fatty acid composition of Halomonas salina, a moderately halophilic bacterium grown at different salt concentrations, is reported. Fatty acids C16:0 and C18:1 were major components and significant amounts of C16:1, C18:0 and cyc-C19:0 were also detected. The results showed clear chemotaxonomic relationships with recognized members of the genus Halomonas. The salt concentration grea...

Nonalcoholic fatty liver disease (NAFLD) is characterized by fat deposition in hepatocytes, and a strong association with nutritional factors. Dietary fatty acids are classified according to their biochemical properties, which confer their bioactive roles. Monounsaturated fatty acids have a dual role in various human and murine models. In contrast, polyunsaturated fatty acids exhibit antiobesit...

In this study, seasonal and sexual variations of fatty acid profiles of Pseudophoxinus fahrettini and Capoeta mauricii which are freshwater fishes in Turkey inland waters were investigated. The monounsaturated fatty acids (MUFAs) values were higher than saturated fatty acids (SFAs) and polyunsaturated fatty acids (PUFAs) values for both species. Also the ratios of MUFAs in P. fahrettini were hi...

The proximate analyses of the muscle were: 15% real protein, 1% non-protein nitrogen, 78% humidity and a fatty acid content lower than 1%. The urea reaches values of 2%. In the lipid fraction 14 fatty acids were identified. Palmitic acid (16:0) and stearic acid (18:0) were the majority fatty acids and represent 61.55% and 33-86%, of the total saturated fatty acids. Oleic acid (18:1) was the mos...

AIMS This work reports on one of the first attempts to use biofilm-forming cyanobacteria for biomass and lipid production. METHODS AND RESULTS Three isolates of filamentous cyanobacteria were obtained from biofilms at different Italian sites and characterized by a polyphasic approach, involving microscopic observations, ecology and genetic diversity (studying the 16S rRNA gene). The isolates ...

Palmitoleic acid is a minor monounsaturated fatty acid in the human diet and in blood plasma. Because macadamia oil is at least one potentially large source of palmitoleic acid, we tested its effect on plasma lipid levels against two other dietary fatty acids, oleic acid and palmitic acid. The dietary adjustments, through the use of supplements, provided comparisons of the three test fatty acid...

The lipid composition of cellular membranes is regulated to maintain membrane fluidity. A key enzyme involved in this process is the membrane-bound stearoyl-CoA desaturase (SCD) which is the rate-limiting enzyme in the cellular synthesis of monounsaturated fatty acids from saturated fatty acids. A proper ratio of saturated to monounsaturated fatty acids contributes to membrane fluidity. Alterat...
