“…Biodiesels are fatty acid methyl and ethyl esters derived from renewable lipid sources, and these fuels are good alternatives for fossil fuel because of being renewable, biodegradable and nontoxic (Zlatanov et al 2001;Meng et al 2009;Karatay and Donmez 2010;Liu et al 2010;Kosa and Ragauskas 2011;Chatzifragkou et al 2011). The high cost of biodiesel is the major obstacle for its commercialization.…”

“…The carbon mass fraction (44.4 %) in raw glycerol used in this study was higher than the one (39 %) used by Chatzifragkou et al (28) in the study of the ability of eukaryotic microorganisms to assimilate raw glycerol derived from biodiesel and convert it into products with high added value. Therefore, the concentrations of nitrogen and phosphorus essential for the cell growth of the parboiled rice effl uent and the carbon mass fraction in raw glycerol infl uence the transformation of these materials into potential sources of such nutrients in the culture medium used in this study.…”

SummarySearch for naturally grown food has stimulated the biotechnological production of carotenoids. Therefore, the use of the yeast Xanthophyllomonas dendrorhous has been researched due to its abilities to assimilate diff erent sources as substrates and to produce high amounts of carotenoids. Furthermore, alternative sources have been used as the culture medium to reduce costs and environmental impact. A potent carotenoid is astaxanthin in view of its health-promoting and antioxidative properties. It consists of diff erent geometrical isomers with trans and cis confi guration. In X. dendrorhous this carotenoid is mostly found in the trans form, but cis isomers can also be found. Carotenoid production was investigated in culture medium containing by-products such as raw glycerol (from biodiesel) and parboiled rice effl uent. The eff ects of the culture medium components on biomass concentration and specifi c and volumetric productions of carotenoids were verifi ed by the Plackett -Burman design. Cultivations were carried out with yeast Xanthophyllomonas dendrorhous NRRL Y-17268 at 25 °C and 150 rpm for 168 h. In this study, maximum production of carotenoids was obtained under the following conditions (in g/L): raw glycerol 10, glucose 10, yeast extract 10, malt extract 10 and peptone 1 at pH=6. Resulting specifi c and volumetric productions of carotenoids were 326.8 and 4.1 μg/g, respectively.

“…Comparative study revealed that yeast Rhodotorula sp. accumulated only up to 22 % (w/w), where as fungi have higher capacity to accumulate up to 42.6 % (wt/wt, of dry biomass) [105]. Accumulation of lipid by Lipomyces lipofer with CG as feed was reported to be 5.46 g/L, which constituted 57.64 % of the total biomass.…”

The biodiesel industry has the potential to meet the fuel requirements in the future. A few inherent lacunae of this bioprocess are the effluent, which is 10 % of the actual product, and the fact that it is 85 % glycerol along with a few impurities. Biological treatments of wastes have been known as a dependable and economical direction of overseeing them and bring some value added products as well. A novel eco-biotechnological strategy employs metabolically diverse bacteria, which ensures higher reproducibility and economics. In this article, we have opined, which organisms and what bioproducts should be the focus, while exploiting glycerol as feed.
