Biotechnological conversions of crude glycerol, residue deriving from biodiesel production facilities, by strains of the yeast Yarrowia lipolytica
(Corresponding) Papanikolaou S., Diamantopoulou P., Sarris D., Aggelis G.
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
Lipid production by Rhodosporidium toruloides growing on media presenting composition similarities with the spent sulfite liquor in batch and fed-batch cultures
Michou S., Vastarouchaa E., Sarris D., Kalantzi O., (Corresponding) Papanikolaou S.
Topic:
Environmental biotechnology and bioenergy
Aim of this study is to explore the effect of sodium lignosulfonate (SL), a paper industry by-product, on cell growth and lipid production by the yeast Rhodosporidium toruloides, cultivated on xylose-based media, that mimic the principal waste-stream originated from paper production facilities (viz...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
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
Screening strains of genus Pleurotus for biomass production in solid state fermentation of agricultural residues
(Corresponding) Diamantopoulou P., Melanouri E., Papanikolaou S.
Topic:
Solid waste management
The ability of several strains belonging to Pleurotus ostreatus and P. eryngii mushroom genera to grow on various agricultural residues was examined and their mycelium growth rates and biomass production (estimated as glucosamine content) were compared. Four P. ostreatus (AMRL 137, 144, 147, 150)...Read more
Production parameters and nutritional value of Pleurotus ostreatus mushroom cultivated on agricultural wastes
Melanouri I., Fourtaka K., Papanikolaou S., (Corresponding) Diamantopoulou P.
Topic:
Agroforestry, forest and agricultural sustainability
The influence of two alternative agro-residues (barley and oat straw-ΒΟ and beech wood residues-ΒW) used as main cultivation substrates in respect to wheat straw-WS was examined on the production and quality characteristics of Pleurotus ostreatus, strain AMRL 144. Evaluation included fungal bio-...Read more
Detoxification of molasses and production of mycelial mass and polysaccharides from Morchella conica mushroom.
Dedousi M., Diamantis I., Melanouri E., Fourtaka K., (Corresponding) Diamantopoulou P.
Topic:
Agroforestry, forest and agricultural sustainability
The impact of molasses on the fungal mass, valuable secondary metabolites’ production and quality characteristics of the edible wild ascomycetous Morchella conica, strain AMRL78 was examined in this study. Morchella mycelium were produced in submerged, static and agitated cultures and the C/N ratio...Read more
Biotechnological treatment of oil mill waste-water to produce high value-added mycelial products.
Diamantis I., Dedousi M., Melanouri E., Fourtaka K., (Corresponding) Diamantopoulou P.
Topic:
Agroforestry, forest and agricultural sustainability
Several trials with Pleurotus pulmonarius mushroom were carried out in liquid state cultures, in synthetic media containing commercial glycose and olive mill wastewater (OMW) with phenolics concentration adjusted to 10% and 30% v/v. Results demonstrated that at the end of fermentation period the...Read more
Analysis of the content of germanium, tellurium and thallium in the grounded waste of electronic equipment
(Corresponding) Fornalczyk A., Willner J., Jablonska-Czapla M., Rachwal M.
Topic:
Hazardous waste management
The article draws attention to the problem of the presence in waste electrical, electronic equipment (WEEE) of selected metals from the group of critical metals (germanium), strategic metals (tellurium) and highly toxic elements (thallium). Due to low content of these metals in e-waste, they are...Read more
