Chemical composition and processing techniques of krill and fish press waters are analysed. Ultrafiltration was found to be of use, but only when an efficient removal of protein suspension could be effected. Besides, ultrafiltration requires a complicated set of apparatus. Biological transformation of proteins and lipids with the use of enzymatic preparations and microorganisms is suggested as a possible alternative. Application of microorganisms is more efficient due to the well-known potential of their cells. Future studies on press water technology should focus on developing improved biotechnological methods involving microorganisms.
