[A new culture medium for growing yeast]

Area of Science:

• Microbiology
• Biotechnology
• Geochemistry

Background:

• Saccharomyces cerevisiae is a vital yeast species with broad industrial applications.
• Developing cost-effective and efficient nutrient media is crucial for yeast cultivation.
• Geothermal waters represent an underutilized source of minerals.

Purpose of the Study:

• To develop a novel, simplified nutrient medium for Saccharomyces cerevisiae cultivation.
• To utilize geothermal water as the primary mineral source for the medium.
• To assess the biotechnological properties of yeast biomass grown on the developed medium.

Main Methods:

• Characterization of mineral content in geothermal water.
• Formulation of a nutrient medium using geothermal water and ammonium hydroorthophosphate.
• Cultivation of Saccharomyces cerevisiae in the developed medium.
• Evaluation of yeast biomass for biotechnological properties.

Main Results:

• A complete nutrient medium was successfully formulated by supplementing geothermal water with only ammonium hydroorthophosphate.
• Saccharomyces cerevisiae demonstrated robust growth in the developed medium.
• The recovered yeast biomass exhibited high biotechnological properties.

Conclusions:

• Geothermal water is a viable and effective mineral source for creating a simplified nutrient medium for Saccharomyces cerevisiae.
• This novel medium offers a cost-effective and efficient approach for yeast cultivation.
• The resulting yeast biomass is suitable for applications requiring high biotechnological performance.
