Algal Transgenics and Biotechnology
Transgenesis in algae is a complex and fast-growing technology. Selectable marker genes, promoters, reporter genes, transformation techniques, and other genetic tools and methods are already available for various species and currently ~25 species are accessible to genetic transformation. Fortunately, large-scale sequencing projects are also planned, in progress, or completed for several of thes...
متن کاملAlgal biofuel hopes
the world's smallest. The giant rat is about the size of a cat and has been classified as belonging to the Mallomys genus of rodents. The region has the largest area of tropical forest without roads or trails. Its isolation is helped by its steep mountain slopes and difficult terrain. The Foja mountains rise to 2,200 metres and, although humans live at the base of the mountains, abundant game a...
متن کاملGasification of Phycoremediation Algal Biomass
Microalgae have been utilized in wastewater treatment strategies in various contexts. Uncontrolled algal species are a cheap and effective remediation strategy. This study investigates the thermochemical potential of wastewater treatment algae (phycoremediation) as a means to produce renewable fuel streams and bio-products. Three gasification temperature levels were investigated in an auger gas...
متن کاملQuantitative assay for algal chemotaxis.
A quantitative capillary assay is described for measuring chemoreception in the neritic and littoral unicellular alga Dunaliella tertiolecta. Lucite chemotaxis plates were used in the assay with 3-microliter capillaries. A Coulter Counter was employed to determine algal cell numbers. D. tertiolecta is attracted to ammonium ion with a maximum positive response at 10(-3) M. Inclusion of calcium a...
متن کاملAlgal models in plant biology.
During the last three decades, plant science has focused on model organism-based approaches, particularly on exploiting the powerful system represented by Arabidopsis thaliana, for which there are a wide range of genetic and genomic resources available. Increasingly, however, there is a tendency to broaden analyses to include multiple study organisms in an attempt to understand biological proce...
