Background: Yeasts play diverse roles in human life. Since ancient times, these micro organisms have been used to produce food products and beverages including bread and beer. Nowadays, the biotechnological products of yeast are some of the main components of commercial products. Objective: Some species of yeast such as Saccharomyces cerevisiae and Saccharomyces boulardii are recognized as probiotic yeast with extensive applications in the food and drug industries. However, certain species like Kluyveromyces marxianus are still not recognized as probiotic micro organisms despite their widespread industrial usage. In this study, the application of K. marxianus in preparing food and the medicinal product was reviewed in terms of its beneficial or harmful effects. Methods: Pub Med, Google Scholar, Scopus, and Science Direct databases were searched by using “Probiotics”, “Yeast”, and “Kluyveromyces marxianus”. Results: The findings suggest that K. marxianus can be recognized as a probiotic yeast species. Conclusion: It can be concluded that K. marxianus may be considered as a probiotic micro organism with a variety of commercial and medical applications.

Fed Batch Cultivation

The Kluyveromyces marxianus yeast recently has gained considerable attention due to its applicability in high-value-added product manufacturing. In order to intensify the biosynthesis rate of a target product, reaching high biomass concentrations in the reaction medium is mandatory. Fed-batch processes are an attractive and efficient way how to achieve high cell densities. However, depending on the physiology of the particular microbial strain, an optimal media composition should be used to avoid by-product synthesis and, subsequently, a decrease in overall process effi-ciency. Thus, the aim of the present study was to optimise the synthetic growth medium and feeding solution compositions (in terms of carbon, nitrogen, phosphorous, magnesium, and calcium concentrations) for high cell density K. marxianus fed‑batch cultivations. Additionally, the biomass yields from the vitamin mixture and other macro/microelements were identified. A model predictive control algorithm was successfully applied for a fed-batch cultivation control. Biomass growth and substrate consumption kinetics were compared with the mathematical model predictions. Finally, 2‑phenylethanol biosynthesis was induced and its productivity was estimated. The determined optimal macronutrient ratio for K. marxianus biomass growth was identified as C:N:P = 1:0.07:0.011. The maximal attained yeast biomass concentration was close to 70 g·L-1 and the 2-PE biosynthesis rate was 0.372 g·L−1·h−1, with a yield of 74% from 2-phenylalanine.
