Topic:
Environmental biotechnology and bioenergy
Aim of the present study was to assess the ability of four Yarrowia lipolytica strains (ACA-DC 50109, LFMB Y-20, ATCC 20460 and LMBF Y-45) to grow on biodiesel-derived crude glycerol, the principal residue-stream deriving from biodiesel manufacture. Initial trials were carried out in shake-flasks...Read more
Biotechnological production of polyols through conversions of crude glycerol by newly isolated strains of the yeast Yarrowia lipolytica
Vastaroucha E., Michou S., Kalantzi O., (Corresponding) Papanikolaou S.
Topic:
Environmental biotechnology and bioenergy
The purpose of this study is to investigate the ability of newly isolated Yarrowia lipolytica strains to grow on crude glycerol, the main by-product of the industrial production of biodiesel. In particular, the ability of the yeasts to metabolize glycerol and produce dry cell weight (DCW) and...Read more
Heterotrophic growth of Chlorella vulgaris on crude glycerol
Gougoulias N., Metsoviti M., Grigoriou M., Lamprakopoulos S., Besios A., (Corresponding) Papapolymerou G.
Topic:
Environmental biotechnology and bioenergy
The heterotrophic growth of C. vulgaris using crude glycerol as the sole carbon source was studied in five 5L flasks. Air in each flask was provided at a rate of 300 L/hr and the contents were continuously stirred with a magnetic bar. Temperature, pH and initial inorganic nutrients (nitrogen,...Read more
Production of added-value metabolites during growth of wild-type yeast strains on media composed of biodiesel-derived crude glycerol
Diamantopoulou P., Filippousi R., Sarantou S., Stoforos N., Xenopoulos E., (Corresponding) Papanikolaou S.
Topic:
Environmental biotechnology and bioenergy
Wild-type yeast strains of Metschnikowia sp., Rhodotorula sp. and Rhodosporidium sp. were grown under nitrogen-limited conditions with crude glycerol employed as sole substrate in shake flasks, under nitrogen-limited conditions, with initial glycerol concentration (Glol0) ≈45 g/L. Yeasts presented...Read more
Lipid production by Rhodosporidium toruloides during growth on biodiesel-derived crude glycerol
Sarantou S., Stoforos N., Ourania K., Diamantopoulou P., (Corresponding) Papanikolaou S.
Topic:
Environmental biotechnology and bioenergy
Rhodosporidium toruloides DSM 4444 when grown on biodiesel-derived glycerol under nitrogen-limited conditions was revealed as an efficient microbial lipid produced. This strain when cultivated on glycerol at initial concentration (Gly0) ~50 g/L produced dry cell weight (DCW) =18.1 g/L containing...Read more
