Alison Gail Smith, Lady Hopper FRSB is Professor of Plant Biochemistry in the Department of Plant Sciences at the University of Cambridge, UK. [2] [3] [4] Her research investigates the metabolism of plants, algae and bacteria, in particular vitamin and cofactor biosynthesis. [5] [6] [7] [8]
Smith was educated at the University of Bristol where she was awarded a Bachelor of Science degree in biochemistry in 1977. [9] She moved to the University of Cambridge, to do a Ph.D. investigating the role of a toxin produced by the bacterium Pseudomonas syringae in causing the symptoms of halo blight of green beans, which she completed in 1981. [10]
Smith's research [11] investigates the:
...metabolism of plants, algae and bacteria, in particular vitamin and cofactor biosynthesis, using a wide range of techniques from biochemistry through molecular biology to genomics, coupled with mathematical modeling approaches. The knowledge gained from these studies is being used to explore the potential for metabolic engineering of high value products in plants and algae, and other biotechnological uses of algae, such as for biodiesel production. In parallel, studies of symbiotic interactions between algae and bacteria are providing insights into algal communities in natural ecosystems, and in dense cultures necessary for industrial cultivation. [4]
Research in Smith's group is also investigating the potential for exploitation of algae for carbon capture and storage, algae fuel and algaculture. [12] Her research has been funded by the European Union, [13] the Biotechnology and Biological Sciences Research Council, the Engineering and Physical Sciences Research Council, the Economic and Social Research Council and the Natural Environment Research Council. [14]
She is a council member of the Marine Biological Association of the United Kingdom of the United Kingdom and as a member of the board of the National Institute of Agricultural Botany. [4]
Smith was awarded a Leverhulme Trust Study Abroad Fellowship in 2001 and a best scientific paper award from the Rebeiz Foundation for Basic Research in 2009 for research on Tetrapyrrole profiling in seedlings of the Arabidopsis (rockcress). [15] In 2009, she was awarded an Erskine Fellowship from the University of Canterbury in Christchurch, New Zealand, and she became a Fellow of the Royal Society of Biology (FRSB) in 2012. [3]
Smith was interviewed by Jim Al-Khalili on The Life Scientific , first broadcast on BBC Radio 4 in 2017. [16]
Smith is married to computer scientist Andy Hopper (Sir Andrew Hopper), with whom she has two children. [1] [17]
Algae are any of a large and diverse group of photosynthetic, eukaryotic organisms. The name is an informal term for a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella, Prototheca and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length. Most are aquatic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts. Algae that are carried by water are plankton, specifically phytoplankton.
The Department of Plant Sciences is a department of the University of Cambridge that conducts research and teaching in plant sciences. It was established in 1904, although the university has had a professor of botany since 1724.
Microalgae or microphytes are microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment. They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a few micrometers (μm) to a few hundred micrometers. Unlike higher plants, microalgae do not have roots, stems, or leaves. They are specially adapted to an environment dominated by viscous forces.
Don Grierson is a British geneticist, and Emeritus Professor at University of Nottingham.
Algaculture is a form of aquaculture involving the farming of species of algae.
Dunaliella salina is a type of halophile unicellular green algae especially found in hypersaline environments, such as salt lakes and salt evaporation ponds. Known for its antioxidant activity because of its ability to create a large amount of carotenoids, it is responsible for most of the primary production in hypersaline environments worldwide, and is also used in cosmetics and dietary supplements.
Algal nutrient solutions are made up of a mixture of chemical salts and seawater. Sometimes referred to as "Growth Media", nutrient solutions, provide the materials needed for algae to grow. Nutrient solutions, as opposed to fertilizers, are designed specifically for use in aquatic environments and their composition is much more precise. In a unified system, algal biomass can be collected by utilizing carbon dioxide emanating from power plants and wastewater discharged by both industrial and domestic sources. This approach allows for the concurrent exploitation of the microalgae's capabilities in both carbon dioxide fixation and wastewater treatment. Algae, macroalgae, and microalgae hold promise in addressing critical global challenges. Sustainable development goals can be advanced through algae-based solutions, to promote a healthy global ecosystem.
Howard Griffiths is a physiological ecologist. He is Professor of Plant Ecology in the Department of Plant Sciences at the University of Cambridge, and a Fellow of Clare College, Cambridge. He formerly worked for the University of Dundee in the Department of Biological Sciences. He applies molecular biology techniques and physiology to investigate the regulation of photosynthesis and plant water-use efficiency.
Scenedesmus is a genus of green algae, in the class Chlorophyceae. They are colonial and non-motile. They are one of the most common components of phytoplankton in freshwater habitats worldwide.
Choricystis is a genus of green algae in the class Trebouxiophyceae, considered a characteristic picophytoplankton in freshwater ecosystems. Choricystis, especially the type species Choricystis minor, has been proposed as an effective source of fatty acids for biofuels. Choricystis algacultures have been shown to survive on wastewater. In particular, Choricystis has been proposed as a biological water treatment system for industrial waste produced by the processing of dairy goods.
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.
The enzyme sirohydrochlorin ferrochelatase (EC 4.99.1.4) catalyzes the following reaction:
Red algae, or Rhodophyta, make up one of the oldest groups of eukaryotic algae. The Rhodophyta comprises one of the largest phyla of algae, containing over 7,000 recognized species amidst ongoing taxonomic revisions. The majority of species (6,793) are Florideophyceae, and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, no terrestrial species exist, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity.
Algae fuel in the United States, as with other countries, is under study as a source of biofuel.
