... the fertilizer “Fertika Universal” as a nutrient medium significantly increased the optical density of the initial solution to 0.087, more than doubling the results compared to other conventional media and proving advantageous for industrial-scale cultivation. The study recommends using a reduced initial cell concentration of Chlorella sp. B1 in the inoculum, followed by cultivation at 32 °С with enhanced illumination (52 W) and the addition of 0.9 g/L of carbon dioxide for three days in a 500 ...

... conducted in both English and Russian using the Scopus, ScienceDirect, PubMed, and eLIBRARY.RU databases. The analysis of scientific and official data demonstrated that physical factors of the culture medium, such as temperature, pH, carbon source, and cultivation conditions, influence the yield and properties of BC. The utilization of agricultural and food waste as a culture medium has been shown to enhance the productivity of Komagataeibacter xylinus strains. The combination of BC with other components,...

Cyanobacteria are a promising source of biologically active compounds of various types and are of great interest for their use in biotechnological processes to obtain complexes or individual bioactive substances with different orientations. Selecting optimal cultivation conditions for cyanobacteria will contribute to the rapid accumulation of bacterial biomass and maximize the yield of biologically active substances. This study analyzes the influence of temperature and light spectral composition on the growth ...

Currently, soybeans and soybean derivatives are widely used for food and animal feed. A significant content of carbohydrates in soy molasses makes it possible to use it as a component of a nutrient medium for cultivating microorganisms that produce feed amino acids. The aim of this work was to study the process of biosynthesis of feed amino acids on a soy molasses medium using bacterial strains of the genus Corynebacterium glutamicum. The following research ...
