Utilization of molasses for the production of fat by an oleaginous yeast,Rhodotorula glutinis IIP-30

Lipid production by Lipomyces starkeyi cells in glucose solution without auxiliary nutrients

“…There were no significant changes in fatty acid compositional profile among samples under different culture conditions. Generally speaking, palmitate, oleate and stearate were the three predominant components in lipid samples from oleaginous yeasts (Johnson et al, 1995), although slight change in relative contents could occur according to the cell age or culture conditions (Fakas et al, 2009). …”

Getting Lipids for Biodiesel Production from Oleaginous Fungi

“…Albeit glucose is a very good carbon source for lipid production with oleaginous fungi, molasses, which carbohydrate fraction is mainly composed of sucrose, glucose, and fructose, do not represent a promising raw material for lipid production, since they are characterized by a high nitrogen content which delays the unbalanced growth, where number of cells can not augment anymore and lipids are accumulated (Johnson et al, 1995). Carbons sources obtained from ligno-cellulosic biomasses represent one of the most important potential to produce biodiesel.…”

Selection and identification of oleaginous yeast isolated from soil, animal feed and ruminal fluid for use as feed supplement in dairy cattle

“…However, this level was less than that of lipid content obtained from glucose media (C/N ratio was 140). Johnson et al (1995) illustrated that Rhodotorula glutinis IIP-30 could not produce lipid when using molasses as a carbon source because its C/N molar ratio was unfavourable for lipid production by this strain. This suggested that the ability to accumulate lipid from molasses by oleaginous micro-organisms depended on both their phenotype and C/N molar ratio of media.…”

“…However, numerous studies revealed that lipid accumulation from molasses using oleaginous yeast varied among species (Johnson et al . ; Wu et al . ).…”

“…Molasses, by-product from sugar industrial contains approximately 45% fermentable sugar (sucrose, glucose and fructose) which is a good carbon source for lipid production (Wu et al 2011). However, numerous studies revealed that lipid accumulation from molasses using oleaginous yeast varied among species (Johnson et al 1995;Wu et al 2011). In addition, culture conditions such as nitrogen source played a crucial role in lipid accumulation (Zhu et al 2008).…”
