Recent developments in the applicants and other European laboratories indicate that probiotic bacteria like lactic acid bacteria and bifidobacteria grow very well on media based on hydrolysed fish by-products. Parallel optimization of conditions for by-product processing and conditions for growth of these food-grade bacteria may result in commercially feasible methods for developing probiotic ingredients to be used in food or feed applications. An additional advantage of fish hydrolysates as source of peptones and other important ingredients concerns their kosher status and the fact that they are free of components derived from meat or from plants that may be genetically modified. Finally, marine raw materials are an excellent starting point for enzymatic bioprocessing because they (as opposed to terrestrial raw materials) usually do not contain microbes that survive at the (moderately high) temperatures used during typical enzymatic processing steps. This project aims at optimizing procedures for enzymatic hydrolys is of fresh salmon by-products under mild conditions and to explore the potential of the resulting hydrolysates for production of probiotic bacteria with a documented potential for use in commercially interesting applications. We will particularly focus o n (1) standardizing hydrolysis procedures, (2) identifying key quality parameters other than peptide and aminoacid content (e.g. lipids, antioxidants), and on (3) growing the most fastidious (and promising) probiotic bacteria, especially bifidobacteria and lactobacilli. The project will be conducted in close collaboration with a major salmon production company and its industrial network
