Oily yeasts have been described to be able to accumulate lipids up to 20% of their cellular dry weight. These yeasts represent a minor proportion of the total yeast population, and only 5% of them have been reported as able to accumulate more than 25% of lipids. The oily yeast genera include Yarrowia, Candida, Rhodotorula, Rhodosporidium, Cryptococcus, Trichosporon, and Lipomyces. More specifically, examples of oleaginous yeasts include the species: Lipomyces starkeyi, Rhodosporidium toruloides, Rhodotorula glutinis, and Yarrowia lipolytica. Yeast do exhibit advantages for lipid production over other microbial sources, namely, their duplication times are usually lower than 1 h, are much less affected than plants by season or climate conditions, and their cultures are more easily scaled up than those of microalgae. Additionally, some oily yeasts have been reported to accumulate oil up to 80% of their dry weight and can indeed generate different lipids from different carbon sources or from lipids present in the culture media. Thus, they can vary their lipid composition by replacing the fatty acids present in their triglycerides. Due to the diversity of microorganisms and growth conditions, oily yeasts can be useful for the production of triglycerides, surfactants, or polyunsaturated fatty acids.

Various species of yeasts are gaining attention as producers of nutraceuticals and biofuels and due to their capacity to biodegrade chemical waste. Rhodotorula mucilaginosa is one of the most oleagino...
In this work, Trichosporon fermentans CICC 1368, which has been shown to accumulate cellular lipids efficiently using industry-agricultural wastes, was subjected to preliminary genome analysis, yieldi...
Co-fermentation of glucose, xylose and L-arabinose from lignocellulosic biomass by an oleaginous yeast is anticipated as a method for biodiesel production. However, most yeasts ferment glucose first b...
Oleaginous yeasts can convert sugars to lipids with fatty acid profiles similar to those of vegetable oils, making them attractive for production of biodiesel. Lignocellulosic biomass is an attractive...
The purpose of FiSK Junior is to investigate whether intake of oily fish compared to poultry affects cardiovascular risk markers, cognitive function, and behaviour in healthy children.
This is a randomized double-blinded study examining the effect of topical Acetyl Hexapeptide-8 AH8) for improving the cosmetic appearance and experience of oily skin.
The number of infants and children with allergic disease (dermatitis, allergies, asthma) has increased over the last several decades. This may be related to changes in diet. It is now thou...
Oral isotretinoin is the gold standard drug to treat moderate to severe acne. Other indications like seborrhea, seborrheic dermatitis have been suggested. There is risk of reversible mucoc...

A general term for single-celled rounded fungi that reproduce by budding. Brewers' and bakers' yeasts are SACCHAROMYCES CEREVISIAE; therapeutic dried yeast is YEAST, DRIED.
An area showing altered staining behavior in the nucleus or cytoplasm of a virus-infected cell. Some inclusion bodies represent "virus factories" in which viral nucleic acid or protein is being synthesized; others are merely artifacts of fixation and staining. One example, Negri bodies, are found in the cytoplasm or processes of nerve cells in animals that have died from rabies.
The oily substance secreted by SEBACEOUS GLANDS. It is composed of KERATIN, fat, and cellular debris.
The refined fixed oil obtained from the seed of one or more cultivated varieties of Sesamum indicum. It is used as a solvent and oleaginous vehicle for drugs and has been used internally as a laxative and externally as a skin softener. It is used also in the manufacture of margarine, soap, and cosmetics. (Dorland, 28th ed & Random House Unabridged Dictionary, 2d ed)
Pneumonia due to aspiration or inhalation of various oily or fatty substances.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
