Abstract

An isolate of the green alga Botryococcus braunii collected from Lake Shira in 2022 has been studied for the first time as a producer of degradable bioplastics polyhydroxyalkanoates (PHAs) and hydrocarbons. The compositions of fatty acids, hydrocarbons, and PHAs were determined. The hydrocarbons synthesized by the isolate were mainly represented by dienes with carbon chain lengths C27 and C29. The study demonstrated the inability of the axenic culture of B. braunii to synthesize PHAs and the presence of polymer in the biomass of unialgal and non-axenic culture (up to 7–10 %). The bacterial component of the algal- bacterial consortium was studied, and bacteria Pseudomonas mendocina, Pseudomonas koreensis, and Aeromonas hydrophila, capable of PHA synthesis, were discovered in it and identified. The study showed that the unialgal and non-axenic culture of B. braunii can be a source of not only algal hydrocarbons, but also degradable bioplastics PHAs
