An enzyme that could help accelerate biofuel production
Researchers at Tokyo Institute of Technology have honed in on an enzyme belonging to the glycerol-3-phosphate acyltransferase (GPAT) family as a promising target for increasing biofuel production from the red alga Cyanidioschyzon merolae. Algae are known to store up large amounts of oils called ...
Sediments reveal mercury pollution in Antarctica since the beginning of the industrial period
Mercury has been used and released by humans by multiple processes such as gold and silver mining and emissions of mercury to the atmosphere by coal burning, to name the most important ones. These processes have caused strong enrichment of mercury in the environment especially in aquatic systems. ...
Nanoparticles with a wide range of applying, including medicine, damage cells of microalgae Heterosigma akashivo badly. This algae species is widely spread in the Russian Far East marine area. The acute toxic effect exhibited at concentrations of 100 mg/l of carbon nanotubes (CNTs) and silicon ...
Scientific sleuthing for reproducible results
Researchers found traces of foreign, non-human genetic material in human blood samples. It turned out that it was not a groundbreaking scientific discovery, but mostly the result of contaminated laboratory materials. Scientists led by Associate Prof. Paul Wilmes of the Luxembourg Centre for ...
The biocatalytic production of chemicals should become considerably more sustainable
A carpet of blue-green algae can literally ‘cloud’ the summer’s swimming pleasure at the lake. This is caused by a few strains of photosynthetically active microalgae, also known as cyanobacteria. Other harmless strains of cyanobacteria have great potential for biotechnological applications and ...
Paradigm shift in interpretation of NMR spectra
An interdisciplinary team of researchers at the University of California San Diego has developed a method to identify the molecular structures of natural products that is significantly faster and more accurate than existing methods. The method works like facial recognition for molecular ...
The adhesion of Chlamydomonas, a unicellular alga, to surfaces is light-dependent
Sunlight allows green algae to do more than just carry out photosynthesis.. Some unicellular algae actually use light to switch the adhesion of their flagella to surfaces on and off – a phenomenon first discovered by physicists at the Göttingen Max Planck Institute for Dynamics and ...
Researchers from Bochum have engineered a hydrogen-producing enzyme in the test tube that works as efficiently as the original. The protein - a so-called hydrogenase from green algae - is made up of a protein scaffold and a cofactor. The latter is the reaction centre where the substances that ...
Microalgae need only sunlight and water for the production of hydrogen. However, in order to make hydrogen production by microalgae economically feasible their efficiency has to be increased by 1-2 orders of magnitude. In the current issue of Energy and Environmental Science scientists from the ...
