“…Fig. 2A showed that the increase of molasses concentration from 20% to 75% was accompanied by linear increase of DMW, while the high concentration of molasses negatively affected the lipid accumulation of T. fermentans, which is consistent with previous reports (Yan et al, 2011;Zhang et al, 2011). Even in the assay of Economou et al high sugar concentrations were found to have an inhibitory effect on both biomass growth and lipid production of M. isabellina, through a detailed mathematical model (Economou et al, 2011b).…”

“…Glucose concentration has a significant effect on cell growth and lipid accumulation in batch cultures (Li et al 2007Papanikolaou et al 2009Zhang et al 2011). Such preliminary studies are necessary to ascertain the nutrient conditions in order to select a strain with the relevant FAME profile.…”

Single cell oils (SCOs) accumulated by oleaginous yeasts have emerged as potential alternative feedstocks for biodiesel production. As lipid accumulation is species and substrate specific, selection of an appropriate strain is critical. Five strains of Y. lipolytica, a known model oleaginous yeast, were investigated to explore their potential for biodiesel production when grown on glucose and inexpensive wastes. All the strains were found to accumulate > 20% (w/w) of their dry cell mass as lipids with neutral lipid as the major fraction when grown on glucose and on wastes such as waste cooking oil (WCO), waste motor oil (WMO). However, amongst them, Y. lipolytica NCIM 3589, a tropical marine yeast, exhibited a maximal lipid/biomass coefficient, YL/X on 30 g L-1 glucose (0.29 g g-1) and on 100 g L-1 WCO (0.43 g g-1) with a high content of saturated and monounsaturated fatty acids similar to conventional vegetable oils used for biodiesel production. The experimentally determined and predicted biodiesel properties of strain 3589 when grown on glucose and WCO, such as density (0.81 and 1.04 g cm-3), viscosity (4.44 and 3.6 mm2 s-1), SN (190.81 and 256), IV (65.7 and 37.8) and CN (56.6 and 50.8) are reported for the first time for Y. lipolytica and correlate well with specified standards. Thus, the SCO of oleaginous tropical marine yeast Y. lipolytica NCIM 3589 could be used as a potential feedstock for biodiesel production.

“…In Mortierella circinelloides, overexpression of ME enhanced lipid accumulation (Zhang et al, 2011), whereas overexpression of the ME homologous in Yarrowia lipolytica did not result in yield improvement. The final products of FAS are myristic or palmitic acids, depending on the yeast species.…”

“…Cryptococcus curvatus is a yeast with industrial potential as single-cell oil because it can grow and accumulate lipid on a very broad range of substrates. It requires minimal nutrients for growth, accumulating up to 60% of its cellular dry weight (DW) as intracellular lipid (Meesters et al, 1996;Zhang et al, 2011). Yeasts of the Cryptococcus genus are widely distributed in nature and may be isolated from various substrates such as air, soil, bird excreta, water, animal surfaces and mucosae, leaves, flowers, and decomposing wood.…”
