The invention relates to food microbiology, food technology and biotechnology sector and is directed to production of fermented products and concentrates thereof from fish and marine origin raw materials. The lactic acid bacteria culture Lactobacillus plantarum is proposed, it is isolated from Baltic herring and deposited in the Latvian Strain Collection of Microorganisms under the accession number P 1462,. The strain can be used for fermentation of fish, fish processing by-products and fish origin raw material as well as production of their dry concentrates. The invention shows that relatively non-traditional raw materials, such as fish or fish processing by-products can be used for fermentation. To obtain starter culture suitable for fish fermentation, isolates from Baltic herring (Clupea herenga membra) has been evaluated. The isolated and identified lactic acid bacteria Lactobacillus plantarum strain P 1462 was recognized as most efficient for fish and fish-origin raw materials fermentation and subsequent dehydration by the way of freeze-drying and suitable for obtaining dehydrated, powdered, microbiologically safe, fermented fish product, which, depending on the raw material composition, can be used as a food or feed supplement.
