“…Growth of yeasts at 25 °C was observed previously in MI‐agar plates in order to design a bioprocess of lipid accumulation at this temperature. MI (C/N = 40) and MII (C/N = 110) were selected from literature for similar studies with oleaginous yeasts .…”

The capability of 17 Rhodotorula spp. isolated from Antarctica to accumulate intracellular lipids in nitrogen-limited medium was investigated. As results, 10 isolates were selected by Nile red staining, while 12 isolates were selected as oleaginous by analysis of total lipid content (20.4-73%, w/w of dry biomass). The higher lipid production and accumulation was exhibited for six strains belonging to three species of Rhodotorula (Rhodotorula glutinis, Rhodotorula glacialis, and Rhodotorula laryngis). This is the first report where R. laryngis have been identified within oleaginous specie. Lipid accumulation was evaluated comparatively in two nitrogen-limited glucose-based media (MI and MII). MI (low C/N ratio) was more suitable for biomass and lipid production while in MII (high C/N ratio) total lipid content was improved. R. glutinis R4, R. glacialis R15, and R. glutinis R48 showed high lipid concentrations (4.65-6.93 g L ) and they were able to accumulate large amounts of lipids per gram of biomass (47-77%, w/w). A similar profile in fatty acids composition and content of neutral lipids to vegetable oils was observed, indicating that lipids produced by oleaginous Antarctic yeasts can be considered an alternative feedstock for biodiesel production. Antarctica represents an important source of oleaginous yeasts with adaptive capabilities to accumulate considerable amounts of lipids with biotechnological interest at 15 °C and 25 °C.

“…Based on morphological characteristics and FAME-GC analysis it was identified as Zygosaccharomyces rouxii. Ravikumar et al (2012) worked on biodiesel production from oleaginous fungi which involves the mixture of fatty acyl methyl/ethyl esters, produced from transesterification of neutral lipids. In similar way, Mrinal et al (2011) has studied the comparative lipid profiling of endophytic fungi by FAME analysis techniques.…”

Microbial lipids (biodiesel) can be produced by oleaginous yeasts via converting carbohydrates into lipids under certain conditions. Sudan black 'B' staining technique was used to screen cellular lipid accumulation. Extraction of the bacterial lipids was carried out by Bligh and Dyer method and fatty acid methyl esters were analysed by GC. Primary screening of sample resulted in 22 isolates, out of which 6 isolates were found to generate lipid. After detection of good oleaginous lipid productivity, one best yielding isolate was preferred for upward spring. Secondary selection of potential isolate was based on the production in addition to parameters like pH and nutritional requirements. Lipid from selected isolate CNK 1 was subjected to determination of saponification value and PUFA screening. The isolate CNK1 was identified as Zygrosaccharomyces rouxii by FAME analysis. The above results were promising hence it has importance for supplementary development of the yeast isolate Zygrosaccharomyces rouxii as another source of lipid for biodiesel production.

“…Ils sont capables d'accumuler des triacylglycérols, riche en acides gras polyinsaturés ou ayant une structure spécifique. L'acide oléique (18:1) et linoléique (18:2) ainsi que l'acide palmitique (16:0) ou palmitoléique (C16: 1) sont le plus souvent les acides gras majoritaires retrouvés dans ce type de micro-organismes (Ravikumar et al, 2012). Il existe également plusieurs espèces de champignons capables de stocker de forts taux de lipides ; par exemple le champignon filamenteux Mortierella alliacea accumule principalement de l'acide arachidonique sous forme de triglycérides dans son mycélium (Rossi et al, 2011).…”

Résumé -Cette revue propose un panorama complet des connaissances actuelles sur les microorganismes sources de lipides utilisés comme biocarburant. Elle fournit les éléments nécessaires à la compréhension de la culture des microorganismes (micro-algues, levures, bactéries et champignons) et de leur capacité à accumuler les lipides. Des techniques conventionnelles et innovantes ainsi que des solvants alternatifs pour extraire les lipides ont été détaillés. Mots clés :Lipides / microorganismes / levures / champignons / bactéries / micro-algues / culture / extraction Abstract -Conventional and innovative techniques, and alternative solvents for extraction of lipids from microorganisms. This review presents a complete picture of current knowledge on microorganisms as sources of lipids used as bio fuel. It provides the necessary background about the culture of the microorganisms (microalgae, yeast, bacteria, and fungi) and their ability to accumulate lipids. Conventional and innovative techniques and alternative solvents for extraction of lipids from microorganisms have been detailed. A special focus has been done for lipids from microalgae.
