The article provides information about green microalga Chloroidium saccharophilum (Trebouxiophyceae) whose history of study dates back to more than 100 years. issues its intraspecific variability are considered. We also studied the strain C. IRK–A 230 isolated from a small puddle on southeastern shore Lake Baikal (Republic Buryatia, Russia). Light and electron microscopy molecular phylogeny met...

Within architecture, microalgae are employed to address sustainability issues and mitigate the impacts of anthropogenic carbon dioxide (CO2) emissions. This study proposes digital fabrication ceramic ‘living’ building components as an investigative tool for design conditions. The health chlorophyte (green) microalga Chlorella vulgaris was monitored over two-week periods when immobilized in kapp...

The biosorption characteristics of Cd (II) ions using the living biomass of the marine diatom Phaeodactylum tricornutum were investigated. This microalga is a highly tolerant species to cadmium toxicity; for this reason, it is interesting to know its potential for use in the removal of this metal. The use of living biomass offers better possibilities than that of dead biomass since cadmium can ...

This work shows the results of biosynthesis silver nanoparticles using microalga Chlorella sp, growth media with different concentrations glycerol, between 5%–20%, and light temperature conditions. The synthesis was studied supernatants pellets from autotrophic, heterotrophic mixotrophic cultures microalga. presence verified by ultraviolet-visible spectroscopy samples showing highest concentrat...

In this work, photostability, absorption and emission intensity of coated polycarbonate (PC) sheets with optical brightener (OB) as a wavelength converter material have been investigated. In addition, this coated sheet was used as a wall for microalgae culture flask, as a small scale photobioreactor, for studying the spectral conversion of UV-A radiation to blue light region and its effect ...

The oleaginous microalga Chlorella sp. LAM-H screened from freshwater was proven to be a prospective feedstock for oil production according to its fatty acid composition. In order to enhance lipid production, response surface methodology (RSM) was used with central composite design (CCD) to optimize the heterotrophic cultivation of microalgae. The experiment results showed that a satisfactory s...

The use microalgae biomass for the production of biofuels has received great attention in the last decades. Microalgae biofuels could be important alternative to conventional biofuels since microalgae could be produced at high rates without the need of neither arable land, potable water or competition with food. However, the high energy intensive harvesting processes are limiting the commercial...

Coimmobilization of the freshwater microalga Chlorella vulgaris and the plant-growth-promoting bacterium Azospirillum brasilense in small alginate beads resulted in a significantly increased growth of the microalga. Dry and fresh weight, total number of cells, size of the microalgal clusters (colonies) within the bead, number of microalgal cells per cluster, and the levels of microalgal pigment...

The effect of the herbicide paraquat on the freshwater microalga Chlamydomonas eugametos was studied in function of different parameters such as growth, elemental composition, total lipids, and photosynthetic pigments content and others assayed by flow cytometry (cell viability, cell volume, and granularity). The study reveals that paraquat concentrations above 0.15 microM are toxic for the mic...
