Bacterial assemblages structure in intensive cultivations of the microalga Tetradesmus obliquus.

The present study shows the characterization of the bacterial communities associated with different systems during the cultivation of the microalga Tetradesmus obliquus. For that, sequential cultivation was performed in three different systems: (1) Photobioreactor bench-scale; (2) flat-panel photobioreactor; and (3) thin-layer cascade. Cultures were monitored daily for growth parameters and biomass samples were collected for characterization of bacterial communities using metagenomic.

Anti-cancer Effects of Fucoxanthin on Human Glioblastoma Cell Line.

Background/aim: Glioblastomas (GBMs) are the most malignant primary brain tumor. New treatment strategies against the disease are urgently needed, as therapies are not completely efficient. In this study, we evaluated the antitumorigenic activity of the carotenoid fucoxanthin (Fx) on human GBM cells in vitro.

Carbon biofixation and lipid composition of an acidophilic microalga cultivated on treated wastewater supplied with different CO levels.

This study evaluated productivity, CO biofixation, and lipid content in biomass of the acidophilic microalga LAFIC-004 cultivated with five different carbon dioxide concentrations. The influence of carbon dioxide concentration on nutrient removal and pH was also investigated. Treated wastewater (secondary effluent) was used as culture medium.
