Abstract: Currently, there is a growing consumer demand for alternative protein that is not of animal origin but has similar properties. This demand is due to the fact that agriculture cannot fully meet the needs of the ever-growing world population with sufficient protein, and the fact that the expansion of agricultural land through deforestation has a harmful impact on the environment.

Today, alternative protein is produced from plants, fungi, yeast, algae and even insects, but the most promising solution is the production of protein products by microorganisms from carbon dioxide and hydrogen. This method of protein production does not require a large area and special conditions for farming, does not require large amounts of water for irrigation and pesticide treatment, thus avoiding environmental damage in the form of wastewater pollution or greenhouse gas emissions.

Protein obtained in this way is called single-cell protein (SCP) and has great advantages compared to proteins of plant origin. The protein content in the biomass of microorganisms reaches 70%, and the composition of amino acids is comparable to chicken eggs, in addition to protein it contains other nutrients, vitamins, minerals and fatty acids.

Today SCP is produced by different groups of microorganisms on different substrates. In this article, we have considered microorganisms that synthesise protein from carbon dioxide and hydrogen, which can be obtained by various means such as water electrolysis, natural gas, biogas, waste gas from industrial processes or landfill gas, etc.
