  • NREL produces ethylene via photosynthesis

    Scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have demonstrated a better way to use photosynthesis to produce ethylene, a breakthrough that could change the way materials, chemicals, and transportation fuels are made, and help clean the air. NREL scientists introduced a gene into a cyanobacterium and demonstrated that the organism remained stable ...

  • Rubisco activase best clue for better photosynthesis in fluctuating light

    Scientists and plant breeders who are aiming to improve food production by improving photosynthesis in crop plants, would make a good choice if they chose to change the composition and concentration of the protein Rubisco activase. In conditions where light intensity changes often and strongly, Rubisco activase is an important limiting factor in boosting the photosynthesis process when light ...

  • Biofuel from Algae, Six Decades of Photosynthesis Research at UREM 2015 Conference, Day 3

    Bioethanol may be successfully produced from genetically engineered algae, carbon dioxide and sunlight, Kerstin Baier of Algenol Biofuel Germany told the Umeå Renewable Energy Meeting on its third and final day 27 March. In fact, 4,000 photo bioreactors taking up two acres of land were turning out the very thing at the company’s ...

  • Pilot plant Photanol process operational

    Photanol represents a process in which blue green algae combine photosynthesis with fermentation to convert CO2 under the influence of light in organic products e.g. ethanol, ethylene or lactic acid. After the “proof of concept” was delivered financial government support was obtained to build a pilot plant. This pilot was designed ...

  • Common Pesticide Reduces Food Value of Algae

    SILVER SPRING, Maryland (ENS) - Researchers with the NOAA National Centers for Coastal Ocean Science have identified negative effects of the commonly used herbicide atrazine on phytoplankton, the free-floating algae that form the base of the food chain for aquatic animals. Published in the current issue of the journal 'Pesticide-Biochemistry and Physiology,' the study indicates protein levels ...

  • Plant diversity: the secret to more nitrogen and carbon in soil

    Plants play a key role in soil carbon (C) and nitrogen (N) accumulation. New research suggests that plant diversity may have an important role to play in stimulating C and N storage in some soils. The findings suggest ways to improve carbon sequestration in grasslands and increase biomass production, for example for biofuel crops on nitrogen limited soils. Soil could be an important carbon sink ...

  • Lighting strategies for LEDs in greenhouse horticulture

    The use of assimilation lighting in greenhouse horticulture has increased by 10% per year during the past decade, leading to a considerable increase in electricity consumption. LED lighting systems have a variety of advantages, ranging from their small size, high energy conversion efficiency to the option to emit specific wavelengths. In the EU project HI-LED, Wageningen UR Greenhouse ...

  • The risks of oxygen depletion and enrichment in aquaculture

    Oxygen depletion is a concern on both dry land and in aquatic environments. Dissolved oxygen is present in water and comes from the atmosphere and also photosynthesis by aquatic plants. Dissolved oxygen is necessary to many forms of life including fish, invertebrates, bacteria and plants. Fish and crustaceans obtain oxygen for respiration through their gills, while plant life and phytoplankton ...

  • Increasing aridity will disrupt soil nutrient cycles in global drylands

    The drying of soils under global warming could disrupt the balance of nutrients in large areas of the Earth’s land surface, according to new research. The study focused on ‘drylands’ – arid areas with low levels of rainfall – which support over 38% of the world’s population. Such nutrient imbalances could diminish the provision of ecosystem services, such as ...

  • Nitrogen use by warm-season grasses for biomass production

    Perennial, warm-season grasses are being evaluated as potential renewable energy crops. These species are well-suited for the production of biomass for energy applications because they utilize C4 photosynthesis and are perennial. Grasses that employ the C4 photosynthetic pathway use water, nitrogen (N), and solar radiation more efficiently than plants having the C3 pathway, and therefore are ...

  • Effects of chemical fertiliser and animal manure on soil health compared

    Fertilising crops with cattle manure can lead to better soil quality than when synthetic fertiliser is used, recent research indicates. The use of cattle manure in the study led to greater soil fertility by encouraging higher microbial activity, and the researchers suggest that it could potentially improve soil’s ability to cope with periods of difficult growing conditions. The ...

  • OriginOil Announces Breakthrough Hydrogen Harvester Invention

    New Technology Taps Hydrogen Generated by Living Algae LOS ANGELES - OriginOil, Inc. (OOIL), the developer of a breakthrough technology to transform algae, the most promising source of renewable oil, into a true competitor to petroleum, today announced a new invention that generates hydrogen from living algae, providing an additional energy source from bioreactors. In contrast to previously ...

  • IDCs: innovation engine for horticulture

    “We want to show innovations in intensive horticulture and demonstrate how they can be applied in practice. This is the main goal of the Innovation and Demonstration Centres (IDCs) in the Netherlands,” says Sjaak Bakker of Wageningen UR Greenhouse Horticulture. There are currently seven operational IDCs, namely in the field of water , flavour, energy, LED lighting, bulbs and plants, ...

  • Why seedlings always grow towards the light

    Scientists from the Carnegie Institution at Stanford University and Wageningen University, part of Wageningen UR, have discovered how cells in the stems of seedlings use blue light to grow towards the light. During earlier research it was discovered that the cells in the seedling stems responded to blue light used in the microscope. The scientists have now discovered how the blue light causes ...

  • ESA investigates new methods of mapping tropical forest from space

    Tropical rainforests play a crucial role in Earth's carbon cycle by absorbing carbon from the atmosphere and storing it in biomass. However, mapping these carbon stocks from space poses a huge technical challenge. An airborne campaign, being carried out in South America, is showing how spaceborne radar could be an answer. In order to improve our understanding of the carbon cycle, more accurate ...

  • GMO crops could expect a brighter future

    One of the touchier areas of scientific research – in much of Europe, at least – is the genetic manipulation of food plants, seaweed and algae to try to produce more food or provide better rates of conversion into biofuels. But across the Atlantic genetically-modified crops (GMOs) are increasingly a different story. They are a deeply controversial subject ...
