“…Afterward, the upper layer containing biodiesel was separated by petroleum ether. Fatty acid methyl esters were analyzed by GC-MS (HP5890, serieII gas chromatography, HP 5972 mass selective detector) (Enshaeieh et al 2012). …”

“…It was shown that optimization of chemical parameters such as carbon and nitrogen sources, carbon concentration and ammonium concentration can effect on lipid production in oleaginous yeasts (Enshaeieh et al 2013b). Also, the effect of different carbon sources such as glucose, xylose, glycerol and rice bran and different nitrogen sources such as yeast extract, peptone, urea, (NH4) 2 SO 4 and NH 4 Cl was investigated on lipid production (Enshaeieh et al 2012). In another research, the effect of physical parameters on lipid production by oleaginous yeasts was evaluated (Enshaeieh et al 2013a); so medium composition and fermentation condition have much effect on lipid production.…”

“…(Leesing and Baojungharn 2011) isolated oleaginous strain Torulaspora globosa YU5/2 and reported lipid production of 4.16 g/L in nitrogen-limited medium with 80 g/L glucose as a carbon source. Most of investigations on lipid production focus on glucose, but the high cost of this substrate persuades much effort to find low-cost carbon sources such as lignocellulosic materials and also oleaginous yeasts that can utilize this substrate (Enshaeieh et al 2012). SCO production from lignocellulosic materials containing xylose attracted a lot of attention, and yeast strains with the ability of using xylose in lignocellulosic hydrolysate have potential for industrial application.…”

Application of microorganisms with ability of using environmental wastes such as lignocellulosic materials for converting them to high-value products is important from economical point of view. Valuable products such as single cell oil (SCO) have a high potential to be used in various industrial fields including biodiesel production. Other important products are polyalcohols like xylitol, which are applicable in the food and pharmaceutical industries. In this study, Rhodotorula yeast was isolated from the leaves of Benjamin. Afterward, SCO production was evaluated in a nitrogen-limited medium, and the obtained oil was analyzed by gas chromatography-mass spectrometery. Moreover, xylitol was produced in a media containing xylose and analyzed by high-performance liquid chromatography technique. The yeast strain was identified using polymerase chain reaction method. SCO and xylitol production was also evaluated in a medium containing lignocellulosic materials and other forestry residues. This strain produced SCO and dry biomass of 9.7 and 16.14 g/L, respectively. In addition, in a medium with 140 g/L of xylose, xylitol production was found to be 49.28 g/L. Among waste materials, lipid content of 49 % on grass hydrolysate was found to be incredible. The obtained strain was identified as Rhodotorula mucilaginosa. The results of this study show that by the isolation of yeast with the potential of making use of waste materials, highvalue products can be obtained. Therefore, it can be concluded that the mentioned bioprocess has not only environmental benefits but also is very important from economical view.

“…Amongst them, Rhodotorulla 110 utilizes glucose as a sole carbon source, yeast extract and ammonium sulphate as a nitrogen source to give high lipid content. Although rice bran is the best carbon source which could be used for lipid accumulation in these yeast cells due to its low cost, other sources which could be used as carbon sources are glucose, sucrose, lactose and soluble starch [3,20].…”

We all are aware that the depletion of the fossil fuel reservoirs has lead to an urgent search for alternative forms of present day fuels. The possible solution could come from biofuels, especially biodiesel. Biodiesel could be produced from plants, microorganisms, fungi, wastewater, microalgae etc., but these sources suffer from one or more drawbacks. However, microalgae could serve as the best source for biodiesel production since it does not lead to a land versus fuel confl ict. This chapter is mainly focused on the sources for the production of biodiesel, biodiesel production processes, catalysis involved and the factors affecting biodiesel production. We have to understand that for the best utilization of biodiesel in diesel engines, we have to incorporate technical modifi cations in traditional diesel engines so that biodiesel production could be promoted commercially.

Today's biotechnologists seek new biocatalysts to meet the growing demand for the bioproducts. This review critically evaluates the potential use of Y. lipolytica as an oleaginous cell factory platform. This yeast has undergone extensive modifications for converting a wide range of hydrophobic and hydrophilic biomass, including alkane, oil, glycerol, and sugars to fatty acid-based products. This article highlights challenges in the development of this platform and provides an overview of strategies to enhance its potential in the sustainable production of biodiesel, functional dietary lipid compounds, and other value-added oleochemical compounds. Future applications of the recombinant Y. lipolytica platform are also discussed.
