An innovative green iron-fertilizer, produced biotechnologically, for correcting iron chlorosis of soybean plants grown in calcareous soils
(Corresponding) Soares H.
Topic:
Environmental biotechnology and bioenergy
Iron deficiency is one of the main causes of chlorosis in plants, which leads to the loss in the field crops quality and yield. Iron-deficiency is a worldwide problem, particularly sever in calcareous soils (about 30% of world´s land surface).
The current use of synthetic iron-chelates to prevent...Read more

Anaerobic digestion of long-chain fatty acids (oleic, palmitic, stearic) with whey protein as the emulsifier
(Corresponding) Eftaxias A., Michailidis C., Diamantis V., Aivasidis A.
Topic:
Environmental biotechnology and bioenergy
Long chain fatty acids are suitable for biogas production, however, they are often responsible for process inhibition, due to their high toxicity even at low concentrations. In this study, anaerobic co-digestion of whey protein emulsified with oleic, palmitic or stearic acid were examined in...Read more

High-rate anaerobic co-digestion of agro-industrial wastes combined with ammonia recovery and biogas purification
Eftaxias A., Georgiou D., (Corresponding) Diamantis V., Koumara A., Koskinari M., Aivasidis A.
Topic:
Environmental biotechnology and bioenergy
Screened dairy manure, pressure-sterilized animal by-products, and cheese whey were co-digested in a Plug Flow Reactor (PFR) over a period of 150 days. The mixture was characterized by TCOD = 70±8 g/L, SCOD = 26±6 g/L, NH4-N = 1.5±0.3 g/L, TSS = 20±5 g/L, VSS = 18±6 g/L, TS = 33±5 g/L, VS = 26±2 g/...Read more
Thermolysis and kinetic parameters determination of biomass fuel powders by differential thermal gravimetric analysis (TGA/DTG/DTA)
(Corresponding) KUMAR p.
Topic:
Environmental biotechnology and bioenergy
The kinetics of the thermal decomposition of the agriculture residues were evaluated using a differential thermo-gravimetric analyser under a non-isothermal condition. The direct Arrhenius plot method and the integral method were applied for the determination of kinetic parameters: activation...Read more

Pyrolysis of Spirulina sp. Microalgae: Effect of Temperature on Chemical Compositions of Bio-Oil and Aqueous Phase
(Corresponding) Özçakır G., Karaduman A.
Topic:
Environmental biotechnology and bioenergy
Pyrolysis of Spirulina sp. Microalgae was carried out in a semi-batch glass reactor system. Effect of temperature on the yields of pyrolytic products (gaseous, liquid and solid residue) and chemical composition of the liquid products were investigated. All experiments were performed in 25 mL/min...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
Co-Pyrolysis of Corn Stover with Plastic: Optimization Based on Synergy
(Corresponding) Salvilla J., Rollon A., De Luna M.
Topic:
Environmental biotechnology and bioenergy
The co-pyrolysis of lignocellulosic wastes such as Corn stover with plastic has been found to improve the both the yield and quality of pyrolysis oil and gas products. In this study, the co-pyrolysis of Corn stover (CS) with plastic (LDPE, and PP) were studied through thermogravimetric analysis...Read more
Volatile Organic Compounds (VOCs) are toxic for the environment and human health and their tendency to readily volatilize in the atmosphere leads to problems connected to odours annoyance. The conventional treatments for VOCs gaseous emissions conventionally entail the application of chemical-...Read more
Red Mud as a Secondary Source of Scarce Metals - Recovery using Red Microalgae
Náhlík V., Čížková M., Singh A., Bišová K., Mezricky D., Rucki M., (Corresponding) Vítová M.
Topic:
Environmental biotechnology and bioenergy
Red mud is a by-product of the production of alumina from bauxite ore. Less than 2% of the red mud produced is currently being reused. The red mud contains a number of residual elements, some at a considerable concentration. The red microalga Galdieria sulphuraria was used to test the accumulation...Read more

Untargeted screening analysis for mycosporines and mycosporine-like amino-acids in algae by mass spectrometry
(Corresponding) Parailloux M., Godin S., C.M. Fernandes S., Lobinski R.
Topic:
Environmental biotechnology and bioenergy
Mycosporines and mycosporine-like amino acids have been described as natural sunscreens and antioxidant compounds presenting a great potential for health and cosmetic applications. Herein, an untargeted screening approach for mycosporines and mycosporine-like amino acids (MAAs) was developed by the...Read more
