    Optogenetics originates from an observation by Ferdinand Cohn [69] that certain unicellular algae exhibit phototropism to blue but not red light. Mast () localized this algal light behavior to an orange eye spot [70] (Fig. 6). - Explore torhertzog's board "MICROSCOPY" on Pinterest.

    Microalgal biomass is unicellular organisms which mean they have only one cell. Microalgae biomass contains compounds like protein, carbohydrates, lipids and nucleic acid. The percentages of compounds vary with the type of algae. Under good condition, biomass of green algae can be double in . Haematococcus pluvialis is known to be a natural source of antioxidants for numerous applications. In this study, an oleoresin rich in carotenoids extracted by supercritical CO2 treatment of H. pluvialis was extensively characterized for its antioxidant capacity. Carotenoid content, fatty acid profile, total phenol content, antioxidant capacity, and viscosity of the oleoresin were determined Author: Mari Carmen Ruiz-Domínguez, Carolina Espinosa, Adrián Paredes, Jenifer Palma, Carolina Jaime, Carlos.

    Freshwater Algae of North America: Ecology and Classification, Second Edition is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America. The book provides essential taxonomic and ecological information about one of the most diverse and ubiquitous groups of organisms on earth.

Fine Structure and Phylogeny of Green Algal Photobionts in the Microfilamentous Genus Psoroglaena (Verrucariaceae, Lichen-Forming Ascomycetes) June Plant Biology 9(3) Chlamydomonas nivalis is a unicellular red-coloured photosynthetic green alga that is found in the snowfields of the alps and polar regions all over the world.

They are one of the main algae responsible for causing the phenomenon of watermelon snow, where patches of snow appear red or first account of microbial communities that form red snow was made by : Chlorophyceae.

It is believed that eukaryotes arise from prokaryotes, which means that organelles can form de novo in prokaryotes.

Such events, however, had not been observed previously. Here, we report the biogenesis of organelles in the endosymbiotic cyanobacterium TDX16 (prokaryote) that was released from its senescent/necrotic host cell of green alga Haematococcus pluvialis (eukaryote).Author: Qinglin Dong, Xiangying Xing, Yang Han, Xiaolin Wei, Shuo Zhang.

Freshwater Algae: Identification and Use as Bioindicators is divided into two parts. Microalgae biomass has garnered significant attention as a renewable energy feedstock and alternative to petroleum-based fuels. The diverse metabolism of green microalgae species additionally provides opportunities for recovery of products for feed, food, nutraceutical, cosmetic, and biopharmaceutical industries.
