A Comparative Study of Amino Acids in the Muscle of Different Species of Fish
Brækkan, Olaf R.; Boge, Gjermund (Fiskeridirektoratets skrifter / Serie Teknologiske undersøkelser;Vol. 4, No. 3, Research report, 1962)1. The complete amino acid composition in the muscles of ten common food fishes has been investigated by microbiological methods. Each amino acid was determined simultaneously in all samples, thus making a direct comparison ... -
Further studies on Vitamins and the Reproductive Cycle of Ovaries In Cod (Gadus morrhua)
Brækkan, Olaf R.; Boge, Gjermund (Fiskeridirektoratets skrifter / Serie Teknologiske undersøkelser;Vol. 4, No. 2, Research report, 1962)The relations between vitamin B6, vitamin B12, biotin and total dry matter and the reproductive cycle of the ovaries in cod has been investigated. The stage of maturation or regeneration was expressed as the percentage ... -
Growth Inhibitory Effect of Extracts from Milt (Testis) of Different Fishes and of Pure Protamines on Microorganisms
Brækkan, Olaf R.; Boge, Gjermund (Fiskeridirektoratets skrifter / Serie Teknologiske undersøkelser;Vol. 4, No. 6, Research report, 1964)A method has been described for the isolation of protamine from the milt (testes) of fish, employing direct extraction of the organ with dilute sulfuric acid, followed by stepwise precipitation with ethanol. The growth ... -
