Selenium is considered an essential component of all living organisms. The use of yeasts as a selenium supplement in human nutrition has gained much interest over the last decade. The accumulation and biochemical transformation of selenium in yeast cells is particularly interesting to many researchers. In this article, we present the results of the determination of selenium and selenomethionine content in the biomass of feed yeast Candida utilis ATCC 9950 obtained from the culture grown in a… 
Effect of Selenium on Lipid and Amino Acid Metabolism in Yeast Cells
TLDR
The results indicate that selenium may induce lipid peroxidation, which consequently affects the loss of integrity of the cytoplasmic membrane and can be used to prepare a novel formula of dietary supplements, which can be applied directly to various diets for both humans and animals.
ACCUMULATION OF SELENIUM BY DIFFERENT YEAST CELLS
Selenium (Se) may play a beneficial role in multi-factorial diseases with genetic and environmental linkages via regulation seleno-proteins activity. The supply of food supplemented with Se-enriched
Effect of selenium uptake on growth metabolism in yeasts for the production of enriched single-cell protein using agro-industrial by-products
The use of agro-industrial by-products as feedstock for selenium-enriched yeast biomass production is an innovative and low-cost method. Thus, the present study aims for the utilization of sugarcane
Improvement of selenium enrichment in Rhodotorula glutinis X-20 through combining process optimization and selenium transport
TLDR
The results indicate that high selenium-enrichment ability and biomass production can be achieved through combining process optimization and regulation of seenium transport.
Selenium–Fascinating Microelement, Properties and Sources in Food
TLDR
It is essential to supplement the deficiency of this micronutrient with selenium-enriched food or yeast cell biomass in the diet, as this element has the highest activity as a free radical scavenger and anti-cancer agent.
A New Approach for the Production of Selenium-Enriched and Probiotic Yeast Biomass from Agro-Industrial by-Products in a Stirred-Tank Bioreactor
TLDR
It is demonstrated that starchy acid hydrolysates are low-cost and efficient substrates for the production of yeast biomass and derivate products and may contribute to further studies for a sustainable development of biorefinery technologies.
Speciation Analysis of Selenium in Candida utilis Yeast Cells Using HPLC-ICP-MS and UHPLC-ESI-Orbitrap MS Techniques
Selenium plays a key role in the proper metabolism of living organisms. The search for new selenium compounds opens up new possibilities for understanding selenometabolome in yeast cells. This study
Effect of Selenium on the Growth and Lipid Accumulation of Yarrowia lipolytica Yeast
TLDR
It seems that Se influenced the activity or the expression of desaturases and elongase in both strains, and the supplementation of growth medium with Se affected cell morphology, as well as the size and distribution of lipid droplets inside the yeast cells.
Biotechnological use of Candida yeasts in the food industry: A review
TLDR
Some directions for biotechnological use of Candida yeasts are presented, related to the production of extracellular metabolites such as citric acid, ethanol, xylitol, erythritol, biosurfactants, and exopolysaccharides, used in the food processing industry, the pharmaceutical industry, and the cosmetic industry.
Selenium Biofortification: Roles, Mechanisms, Responses and Prospects
TLDR
This current review summarizes the roles, responses, prospects and mechanisms of Se in human nutrition and elaborates how biofortification is a plausible approach to resolving Se-deficiency in humans and other animals.
