Technology for Growing Yeast on Nutrient Media from Silphium perfoliatum Green Mass

Abstract

It has been found that the cup plant green mass is a promising substrate to culture yeasts, including Saccharomyces cerevisiae. A comparative study of efficiency to use the dried and intact green mass of this plant as a component of the medium for yeast cultivation was carried out. In the Republic of Ossetia-Alania, S. perfoliatum is a perennial, high-yield introduced species, yielding up to 1500 cwt of green mass per hectare. Using the cup plant green mass in to grow yeasts is economically beneficial, due to its high nutrient content. Key words: yeasts, culture media, cup plant, hydrolysis, biomass Funding - The work was financed by the extra-budgetary fund of the Gorsky State Agrarian University.

The yield of green phytomass of Siplhium perfoliatum L., newly-introduced energy crop tested on marginal heavy soils under Central European continental climate

“…By results of Hryniewicz et al (2021) According to study of Tsugkiev et al (2021) from Republic of Ossetia-Alania, cup plant is an introduced perennial crop with high-yield potential, yielding up to 150 t/ha of green mass in climatic conditions of the south Caucasian juncture of Europe and Asia. By worldwide review of Peni et al (2020), higher yields of cup plant phytomass can be obtained at higher precipitation levels, with the use of fertilizers and an adequate type of plantation, whereas the mean dry matter yield of the crop was 13.3 t/ha, ranged from 2 to over 32 t/ha.…”

Ligno-cellulose quality and calorific value of green phytomass of Silphium perfoliatum L. cultivated on marginal soils under conditions of moderate continental climate of Central Europe

“…Lesser-known plants with the prospect of being used not only for energy purposes include the cup plant Silphium perfoliatum L, a promising novel crop that is still not widely distributed (Marišová et al, 2016;Cumplido-Marin et al, 2020;Hauptvogel et al, 2022;Reinhardt et al, 2022). The indisputable advantage of the cup plant is the suitability of the phytomass for various uses, while most of recent research works are focused on potential in biogas production (Siwek et al, 2019;Guo et al, 2020;Kowalska et al, 2020;von Cossel et al, 2020;Witaszek et al, 2022) and there is little knowledge and information enabling reliable cultivation technology (Shittenhelm et al, 2021;Hryniewicz et al, 2021;Tsugkiev et al, 2021;MarieEnde at al., 2021). Even the forms of usability themselves are not yet sufficiently parameterized and it concerns further energy and feed purposes, pharmaceutical uses or honey production, and the protection of animals and their living space is also worth mentioning.…”
