High FAME yield Biodiesel from microalgae through nanocatalytic transesterification process.

Mittal V., (Corresponding) Ghosh U.

Topic:

Environmental biotechnology and bioenergy

Biodiesel production from microalgae is significantly important when reserves of petro-diesel are depleting, and utilization of vegetable oil-based fuel leads to food scarcity. The rapid growth and high lipid content of microalgae is an ideal feedstock for biodiesel production. The use of...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

Evaluation of the potential of four microalgal-bacterial symbiotic association on wastewater treatment and lipid accumulation

Talapatra K., Mittal V., (Corresponding) Ghosh U., Gautam R.

Topic:

Environmental biotechnology and bioenergy

Microalgae-bacteria symbiotic systems have demonstrated greater benefits over the pure culture of microalgae. The existence of certain bacteria will increase the quality of sewage purification and also reduce the associated high capital cost for maintaining the pure culture of microalgae. In this...Read more

Microalgae biomass cultivation and harvesting optimization in biological carbon capture and utilization systems for biofuels production

(Corresponding) Senatore V., Zarra T., Oliva G., Buonerba A., Napodano P., Belgiorno V., Naddeo V.

Topic:

Environmental biotechnology and bioenergy

The boosting of greenhouse gas (GHG) emissions into the atmosphere due to anthropogenic activity contributes significantly to climate change. According to the Green Deal by 2050, net zero greenhouse gas emissions must be achieved. Therefore, actions are needed in order to control GHG emissions. The...Read more

The effect of HRT in the successful bioaugmentation of CSTRs working under ammonia toxicity

Tzenos C., Christou M., Kalamaras S., (Corresponding) Kotsopoulos T.

Topic:

Environmental biotechnology and bioenergy

High levels of ammonia is a common inhibitory factor in anaerobic digestion (AD) resulting in low methane production and unbalance of the process. In the present study, the adjustment of the hydraulic retention time (HRT) and the bioaugmentation process (BP) are investigated to counter the negative...Read more
