The production by enzymatic treatment of fish protein hydrolysates (FPH) is a promising route to add value to fisheries proteinic co-products (fish frames, heads etc.). Indeed, FPH possess good nutritional properties and biological activities for food and feed uses. Pressure-driven membrane separations such as ultrafiltration (UF) and nanofiltration (NF) can be used after the hydrolysis to, increase the specific activities of the FPH. This paper discusses the impact of a two-step UF/NF process producing four different fractions on two industrial FPH with different hydrolysis degrees. Fractionation is carried out in "realistic" conditions for an industrial process, on highly concentrated FPH solutions (about 100 g of dry matter/L) at a high volume reduction...

Screening of marine algal extracts for anti-settlement activities against microalgae and macroalgae 5
Hellio, Claire; Berge, Jean-pascal; Beaupoil, Claude; Le Gal, Yves; Bourgougnon, Nathalie.
The ban on the use of TBT-based antifouling paints for boats under 25 m in length has lead to a search for new non-toxic antifoulants. One of the most promising alternative technologies to heavy metal based antifouling paint is the development of antifouling coatings whose active ingredients are naturally occurring compounds from marine organisms. This is based on the principle that marine organisms are also facing the problem of the presence of epibionts on their own surface. In this study, the antifouling activity of a series of aqueous, ethanolic and dichloromethane extracts from 30 algae from the North East Atlantic coast was investigated. The extracts were tested in laboratory assays against species representatives of two major groups of fouling...
