N2 - The composition of Fucus Vesiculosus (F. Vesiculosus) makes it a unique raw material for a variety of substances with a wide range of consumer properties. The composition of the polyphenolic fraction of F. Vesiculosus is characterized by a large amount of phloroglucinol polymers – phlorotannins. Phlorotannins are the target compound of this study. Microwave assisted pretreatments of algae were carried out in order to intensify the extraction of the target compound. The efficiency of pretreatment was evaluated by determining the yield of extractives, polyphenols, and phlorotannins. Chemical composition of polyphenol fraction of F. Vesiculosus algae was studied. The obtained results show that microwave treatment of F. Vesiculosus allows to increase the yield of the target compound 1.6 times with lower energy consumption compared to a reference sample. The obtained extracts have a substantial antibacterial effect on gram-positive and gram-negative bacteria. They also stimulate growth of pea seedlings and can be recommended for use in agriculture as a growth stimulator, for preparation of seeds for sowing, and also as an antibacterial agent that protects both seeds and seedlings from pathogenic bacteria.
