The emulsification of fatty waste from fish processing was studied using different mixing speeds (250–2000 rpm) and a series of surfactants (sodium dodecyl sulfate, sodium cocoyl glutamate, sodium cocoamphoacetate; experimental peptides) at a concentration of 0.1 and 0.3 % with registration of the size distribution of fat droplets and stability of emulsions. Conditions have been found for obtaining finely dispersed and stable emulsions suitable as a biotechnological substrate, providing the possibility of carrying out a sustainable process of cultivating bacteria in the synthesis of bioplastics with high yields (75±5 %) with a complete use of the fatty substrate of 75–80 %
