Characterizing activated carbon synthesized from corn straw aiming water treatment
Silva T., Souza I., Silva C., (Corresponding) Abud A.
Topic:
Environmental biotechnology and bioenergy
The emerging agenda for sustainable development and global warming control searches urgent researches to reduce environmental impacts. In this sense, activated carbons from agroindustrial wastes are widely used as adsorbents in food and pharmaceuticals industries, mainly for the separation and...Read more
Dairy wastewater as growth substrate for biomass and biocompound production by Spirulina platensis
Escolà Oliva G., Zapata López D., Aristizábal Castrillón A., (Corresponding) Arroyave Quiceno C., Poschenrieder C., (Corresponding) Llugany Ollé M.
Topic:
Environmental biotechnology and bioenergy
Spirulina former Arthrospira is a Cyanobacteria with economic applications in agriculture, biofuel production and wastewater management. In order to evaluate the suitability of organic carbon containing wastewater for the production of biomass and biocompounds by Spirulina platensis (UTEX) strain...Read more

Second generation bioethanol production from household food wastes via a newly isolated yeast strain of Wickerhamomyces anomalus
Dazea D., Antonopoulou G., Alexandropoulou M., Ben Atitallah I., Mechichi T., (Corresponding) Ntaikou I., Lyberatos G.
Topic:
Environmental biotechnology and bioenergy
The aim of the present study, was to investigate the efficiency of second generation bioethanol production from the pre-dried and shredded organic fraction of household food waste (food residue biomass, FORBI) using the newly isolated yeast Wickerhamomyces anomalus X19. W. anomalus is a...Read more
Production of PHAs with enhanced properties from sugar-based wastewater in a two stage process
FOUSKAKIS G., STERGIOPOULOU E., ALEXANDROPOULOU M., (Corresponding) ANTONOPOULOU G., NTAIKOU I., LYBERATOS G.
Topic:
Environmental biotechnology and bioenergy
The experimental design of the study was based on two different microbial processes, i.e. anaerobic fermentation of a sugar-based wastewater via mixed acidogenic cultures and aerobic polymerization of the produced acids and alcohols for poly-hydroxy-alkanoates (PHAs) production, via enriched...Read more

Fuel performance of biodiesel produced from transesterification of microalgae was evaluated to assess its potential as alternative fuel in diesel engine. The biodiesel was produced from transesterification of microalgae Chlorella Vulgaris using K-pumice as catalyst. The engine used in the study was...Read more
Cloning and sequencing of the gene encoding the enzyme for the reductive cleavage of diaryl ether bonds of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in Geobacillus thermodenitrificans UZO 3
(Corresponding) Suzuki Y., Nakamura M., Otsuka Y., Sato-Izawa K., Hishiyama S., Kameyama K., Kameyama T., Takahashi A., Katayama Y.
Topic:
Environmental biotechnology and bioenergy
We have previously reported that a cell-free extract prepared from Geobacillus thermodenitrificans UZO 3 reductively cleaves diaryl ether bonds of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD), a dioxin with the highest toxicity, in a sequential fashion producing 3’,4’,4,5-tetrachloro-2-...Read more
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
LED light tailoring in a planar photobioreactor for optimization of microalgae growth.
(Corresponding) Riggio V., Occhipinti A., Grinic D., Zanetti M.
Topic:
Environmental biotechnology and bioenergy
Microalgae are well known for their potential in producing valuable substances for nutraceutical and pharmaceutical industries, as well as a source of biofuel. Currently, the use of the photosynthetic capacity of microalgae is a new alternative for carbon dioxide bio-fixation. Therefore, the...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
