Emerging low-emission production technologies make ethanol an interesting substrate for yeast biotechnology, but information on growth rates and biomass yields of yeasts on ethanol is scarce. Strains of 52 Saccharomycotina yeasts were screened for growth on ethanol. The 21 fastest strains, among which representatives of the Phaffomycetales order were overrepresented, showed specific growth rates in ethanol-grown shake-flask cultures between 0.

- The study investigates how the yeast C. jadinii grows on ethanol as a carbon source, looking specifically at growth rates, energy requirements, and biomass composition across different culture methods.
- In ethanol-limited conditions, C. jadinii CBS 621 achieves effective biomass yields and demonstrates a stable protein content, even at low growth rates, indicating its potential for producing single-cell protein.
- The research also finds that various C. jadinii strains grow rapidly on ethanol, and the results from chemostat cultures can help model production outcomes in larger fed-batch systems, highlighting differences in protein content due to cultivation conditions.
Hydroxylamine is a key intermediate in several biological reactions of the global nitrogen cycle. However, the role of hydroxylamine in anammox is still not fully understood. In this work, the impact of hydroxylamine (also in combination with other substrates) on the metabolism of a planktonic enrichment culture of the anammox species Ca.
