ABSTRACT
Study of the utilization of various amino acids by bacteria inhabiting seawater in the region of the Gdansk
Deep was carried out. The highest percentage of the neustonic and planktonic bacteria utilized glutamic acid,
asparatic acid, histidine and cysteine for their optimal growth, whereas only a small percentage of bacterial
strains utilized serine, phenylalanine, ornithine and glicyne. Significant differences in utilization of individual
amino acids by bacteria inhabiting various water layers occurred.
