A technique for harvesting unicellular algae using colloidal gas aphrons
Unicellular algae have proven to be extremely difficult to separate from their liquid environment, and at the present time no economical process exists. A novel technique using colloidal gas aphrons (CGA) has been investigated for harvesting <i>Chlorella vulgaris</i>, a green algae, from dilute …

Determination of sediment provenance at drift sites using hydrogen isotopes in lipids
… records. We isolated alkenones from cultured unicellular algae (haptophyte Emiliania huxleyi), surface ocean particulate material, and open ocean sediments to determine the extent and variability of hydrogen isotopic fractionation in the di-, tri-, and tetraunsaturated C₃₇ compounds. We then …

Genome scale metabolic modelling of Phaeodactylum tricornutum
Diatoms are photoautotrophic unicellular algae and are among the most abundant, adaptable and diverse marine phytoplankton. Their ability to synthesise lipid as a storage compound (20%-50% dry cell weight) makes them a potential sources of biofuel and high-value commodities such as ω fatty acids. …

Homology Cloning, Heterologous Expression and Characterization of A New Channelrhodopsin
… receptors in the plasma membranes of motile unicellular algae. They function as light-gated cation channels and this channel activity has been exploited to trigger action potentials in neurons with light to control neural circuits (“optogenetics"). Four channelrhodopsins were identified in …

The role of interfacial and 'entropic' enzymes in transitory starch degradation : a mathematical modeling approach
Plants and some unicellular algae store carbon in the form of transitory starch on a diurnal basis. The turnover of this glucose polymer is tightly regulated and timely synthesis as well as mobilization is essential to provide energy for heterotrophic growth. Especially for starch degradation, …

HISTOLOGICAL RESPONSES OF THE SEA ANEMONE A. PALLIDA TO BLEACHING INDUCING STRESSES
… the symbiosis established between corals and unicellular algae of the genus Symbiodinium that provide them with photosynthesis-derived carbon. Unfortunately, with the climatic upheaval that we witness today, the long-term survival of coral reefs could be in jeopardy. Massive loss of symbiotic …

Characterising cyanobacterial and algal bicarbonate transporters using heterologous systems; exploring relationships between sequence, structure and function
… for function were from cyanobacteria and unicellular algae (green algae and a diatom). Screening identified two families of HCO3- transporters that were functional in CAfree. Functional transporters, named SbtA2 and LCIA, were characterised using HCO3- uptake assays which measure the …

Physiological and molecular determinants of the Chlamydomonas reinhardtii pyrenoid
… carboxylase/oxygenase (RuBisCO). Many eukaryotic algae, and a single group of land plants, the hornworts, have an inducible carbon concentrating mechanism (CCM), to overcome these limitations. The efficiency of the CCM is improved when RuBisCO is localised to a subcellular compartment, the …

Functional Evolution and Origin of Enzymes of the Bacterial Glycogen/Starch Biosynthetic Pathway
<p>The goal of scientific discovery is to answer basic questions about how the world around us functions. We accomplish this by constantly questioning, dismantling, reassembling, poking, prodding, and testing every detail until we understand it fully. At times we use this knowledge to engineer …
