“…The results indicated that the inhibitors did not change the lipid composition but induce the biosynthesis of unsaturated fatty acids. The lipid composition for both cases was similar to the fatty acid profiles of palm oil (Saenge et al, 2011). High content of unsaturated fatty acids will lead to satisfactory fuel properties at low temperatures (Zheng et al, 2012).…”

“…[120] The yeast R. glutinis can also accumulate 60.7% (w/w) lipids in a fed-batch cultivation system. [121] Though lipid contents are high in biomass, the overall amount of lipid produced per litre of the culturing medium remains relatively low, with the T. elegans and R. glutinis producing total lipids of only 11.6 and 6.1 g/L from the medium containing 90 and 95 g/L crude glycerol, respectively (Table 4). In addition, the overall lipid yield per gram of glycerol consumed is low.…”

“…[41] This is largely due to a better control of substrate levels preventing substrate inhibition at high glycerol concentrations. [121] Batch cultivation of C. curvatus was negatively impacted by the impurities of crude glycerol compared to pure glycerol. [122] Growth was reduced by 2.5 times when the crude glycerol level was increased from 20 to 40 g/L and almost no growth was observed at 60 g/L.…”

Microbes have been exploited to produce a variety of high-value products such as enzymes, proteins, antibiotics, vitamins, etc. Use of oleaginous microorganisms for production of lipids (commonly called as single cell oils) commenced during the eighteenth century in Germany. Microbial lipids containing special fatty acids such as gamma-linolenic acid, arachidonic acid and docosahexaenoic acid are popularized and are now being produced in a large scale as neutraceuticals and food additives. In the past decade, microbial lipids have been considered as a promising feedstock for biodiesel production due to the contemporary issues on climate change, renewable energy and food security. Recently, various cheap raw materials and biowastes have been explored for economic microbial lipid production, which is considered as a solution to reduce biodiesel production cost and to achieve sustainable management of biowastes. Thus, microbial lipids produced from renewable biomass and biowastes as a second-generation biodiesel feedstock are a promising alternative for vegetable oils. In this review historical development of microbial lipids, biochemistry of lipid accumulation by oleaginous microorganisms, lipid production from various biowastes and renewable materials and cultivation methodologies are reviewed. Microbial lipids as a biodiesel feedstock are also reviewed and discussed.

“…The current study showed that L. starkeyi was able to efficiently convert glycerol to lipids, resulting in a 46.2% of oil content (correspondingly, the lipid productivity was 4.2 g/L). Compared to other oleaginous yeasts such as Rhodotorula glutinis, Cunninghamella echinulate, and Mortierella isabellina, the lipid productivity of L. starkeyi was similar when glycerol was used as the sole carbon sources (Eastering et al 2009;Fakas et al 2009;Saenge et al 2011). The cell growth on the glycerol media, however, seemed to be suppressed because its cell growth rate was slower and its DCW is relatively lower than on the glucose and xylose media.…”

Producing microbial oils via oleaginous yeast fermentation has drawn broad attention in the biodiesel industry. The oleaginous yeast Lipomyces starkeyi utilizing diverse carbon sources including glucose, xylose, glycerol, and willow wood sawdust (WWS) hydrolysate for the biosynthesis of oils in its cell growth were investigated in this study. High carbon/nitrogen ratios within the glucose media significantly increased the lipid content of Lipomyces starkeyi cells and modified the fatty acid composition of lipids, promoting the accumulation of C16:0 fatty acids and saturated fatty acids (C16:0 and C18:0). The accumulation of C18 fatty acids (C18:0, C18:1, and C18:2) and unsaturated fatty acids (C16:1, C18:1, and C18:2) was restricted. When crude glycerol and WWS hydrolysate were used as the sole carbon sources for L. starkeyi fermentation, the dry cell weight, lipid content, and lipid productivity were 9.1 g/L, 46.2%, and 4.2 g/L, respectively, for glycerol, and 8.2 g/L, 42.7%, and 3.5 g/L, respectively, for the hydrolysate solution. This study provides useful information for producing oils with L. starkeyi fermentation using glycerol and WWS hydrolysate as the primary or secondary carbon substrates.
