“…Filamentous fungi cannot be ignored when discussing oleaginous microorganisms. At least two fungal cell oils have been commercialized so far, i.e., microbial oil from the culture of M. circinelloides with a high level of γ-linolenic acid and arachidonic-rich oil from M. alpina [27,33].…”

“…They tend to have lower biomass yields compared to other groups, resulting in fewer lipids per gram of biomass. Additionally, lipid extraction can be difficult, due to their adhesion to cell membranes [27]. Yeasts are also used in the research on the biosynthesis of microbial oil.…”

“…Yeasts are also used in the research on the biosynthesis of microbial oil. Oleaginous yeasts include representatives of such species as Rhodosporidium toruloides, Rhodotorula glutinis, Trichosporon oleaginosus, Lipomyces starkeyi, and Y. lipolytica, the last of which being considered a model organism for studying the mechanisms involved in lipid metabolism covering lipid uptake, their storage, and their deposition or mobilization [27][28][29]. As previously mentioned, the biosynthesis of microbial lipids can take place in two different biochemical pathways, i.e., de novo and ex novo, which involve the synthesis of fatty acid precursors from glucose or the uptake of fatty substances from the environment and their accumulation in lipid bodies, respectively; therefore, the fatty acid composition is largely dependent on the substrate used [30].…”

“…Their properties and composition depend entirely on the microorganisms involved in their biosynthesis. The fatty acid composition of microbial oils typically consists of mainly palmitic and oleic fatty acids, with other common acids like myristic, palmitoleic, stearic, and linoleic, as well as αand γ-linolenic acids, while the oils obtained from algae may be a source of other polyunsaturated fatty acids, like EPA (eicosapentaenoic acid, C20:5) and DHA (docosahexaenoic acid, C22:6) [27].…”

Plant and animal oils and fats currently dominate the edible oil market, but a new sustainable alternative of lipids from single-celled organisms has become advantageous in human nutrition and pharmacy. Single-cell oils (SCOs) are lipids biosynthesized and accumulated in the lipid bodies of oleaginous species of bacteria, yeasts, molds, and algae. The review has investigated SCOs’ composition, with a detailed review of the described beneficial impact in medicine, cosmetics, pharmacy, and nutrition. Although microbial oil has been known for more than 100 years, it was not applied until the 21st century, when commercial SCO production for human use started and administrative regulations governing their use were completed. This article discusses the applications of SCOs, which can be easily found in microorganisms, in the pharmaceutical, cosmetic, and food industries. In addition, some aspects of 15- or 17-carbon-atom-long fatty acids were also pointed out. Furthermore, some challenges for heterotrophic single-cell oil synthesis and improvements in its extraction efficiency have also been concluded, which can further contribute to their broadened use in pharmacy, medicine, cosmetics, and food applications.

“…In contrast, ex novo lipid fermentation can modify the lipid compositions to satisfy the requirements of the chemical or food industries. Thus, improving and upgrading fatty materials utilized as substrates can produce “tailor-made” lipids of high-added value [ 61 ]. The combined production of de novo and ex novo lipids has been studied, for instance, by using the yeast Trichosporon dermatis and a mixed medium combining an acid hydrolysate of corn cob and a soybean.…”

Biodiesel, unlike to its fossil-based homologue (diesel), is renewable. Its use contributes to greater sustainability in the energy sector, mainly by reducing greenhouse gas emissions. Current biodiesel production relies on plant- and animal-related feedstocks, resulting in high final costs to the prices of those raw materials. In addition, the production of those materials competes for arable land and has provoked a heated debate involving their use food vs. fuel. As an alternative, single-cell oils (SCOs) obtained from oleaginous microorganisms are attractive sources as a biofuel precursor due to their high lipid content, and composition similar to vegetable oils and animal fats. To make SCOs competitive from an economic point of view, the use of readily available low-cost substrates becomes essential. This work reviews the most recent advances in microbial oil production from non-synthetic sugar-rich media, particularly sugars from lignocellulosic wastes, highlighting the main challenges and prospects for deploying this technology fully in the framework of a Biorefinery concept.
