Coastal countries have traditionally relied on the existing marine resources (e.g., fishing, food, transport, recreation, and tourism) as well tried to support new economic endeavors (ocean energy, desalination for water supply, seabed mining). Modern societies lifestyle resulted in an increased demand dietary diversity, better health well-being, biomedicines, natural cosmeceuticals, environmental conservation, sustainable energy sources. These societal needs stimulated interest of...

Marine organisms produce a vast diversity of metabolites with biological activities useful for humans, e.g. cytotoxic, antioxidant, anti-microbial, insecticidal, herbicidal, anticancer, pro-osteogenic and pro-regenerative, analgesic, anti-inflammatory, anti-coagulant, cholesterol-lowering, nutritional, photoprotective, horticultural or other beneficial properties. These could help satisfy the increasing demand alternative sources nutraceuticals, pharmaceuticals, cosmeceuticals, food, feed,...

In brined shrimp (ca. 3% NaCl), the effects of three different lactic acid bacteria bacteriocins (crude [6.54 x 10(sup10) U bacteriocin activity {BU}/g] and purified [8.13 10(sup23) BU/g] nisin Z, carnocin UI49 [2.32 10(sup4) BU/g], crude bavaricin A [2.78 BU/g]) on bacterial growth shelf life were compared with those a benzoate-sorbate solution (0.1% each [wt/wt]) control no preservatives. The subjected to treatment was found be 10 days. Carnocin did not extend life, while (a cell-free...

The following study reports on the first thraustochytrid isolates identified from Iceland. They were collected three different locations off northern coast of country (Location A, Skagaströnd; Location B, Hveravík; and C, Eyjafjörður). Using 18S rDNA sequence analysis, Locations A B within Thraustochytrium kinnei species while other Sicyoidochytrium minutum when compared to known strains. Cells isolated ( 2.10 ± 0.70 g/L) 1.54 0.17 produced more biomass than ones C 0.43 0.02 g/L). This...

Marine microphytobenthic community composition in relation to habitat characteristics of sub-tidal flats temperate and Arctic regions is well described. For sub-Arctic areas, especially for northern Icelandic intertidal flats, information sparse or absent. To investigate composition, surface sediments were collected during neap tide at six stations, along two transects the Húnaflói near Skagaströnd from March October 2013. Variations environmental factors considered as density (abundance...

The demand for novel sources of marine oils, which contain polyunsaturated fatty acids (PUFAs), has increased due to the realization importance PUFAs, e.g., docosahexaenoic acid (DHA), in human diet. However, natural supply is limited. By-product peptones (BYPP) intended as a growth medium PUFA-producing strain Sicyoidochytrium minutum family Thraustochytriaceae were produced after several experiments on pancreatic digestion bovine lungs and spleens. S. was able grow containing BYPP made...
