Developing an integrated algal biorefinery

Developing an integrated algal biorefinery

Yogendra Shastri writes in sciencetrends.com about a recently published study that proposes an integrated biorefinery – co-producing fuel, a low-value high-volume product, with other value-added products such as protein, reduced sugar, and polar lipids – which are high value and low volume…

Chemical communication between algae and bacteria

Chemical communication between algae and bacteria

If green algae of the species Chlamydomonas reinhardtii meet Pseudomonas protegens bacteria, their fate is sealed. The bacteria, measuring only some two micrometers, surround the algae, which are around five times larger, and attack them with a deadly toxic cocktail. The algae lose their flagella, which renders…

New algae strain for desert farming

New algae strain for desert farming

Biologists from Abu Dhabi and the United Arab Emirates have engineered a new form of microalgae that can grow rapidly in desert conditions, a discovery they claim could be used to sustainably produce biofuels, animal feed and other bio-based products in otherwise barren environments. The researchers set out…

Photoenzyme allows algae to produce hydrocarbons

Photoenzyme allows algae to produce hydrocarbons

The European Synchrotron Radiation Facility (ESRF) reports that an international team has discovered an enzyme which allows microalgae to convert some of their fatty acids into hydrocarbons using light. This discovery is relevant in the quest of sustainable energy production. Researchers at the CEA (French Atomic…

Measuring evolutionary adaptation to climate change

Measuring evolutionary adaptation to climate change

One challenge facing scientists is to measure evolutionary adaptation — how our environment and the complex web of creatures within it, will respond to changes in their environment due to climate change or other human influences. Traditionally, scientists have tested single or pairs of ecological “drivers” of change…

Lomonosov scientists adjust an algal technology for waste

Lomonosov scientists adjust an algal technology for waste

Members of the Faculty of Biology of the Lomonosov Moscow State University have proven that, under Nordic conditions, wastewaters could be treated with the help of microalgae, while the algal biomass is suitable for processing into biofuel. The Lomonosov scientists presented the optimized technique…

Did HABs fell the mighty dinosaurs?

Did HABs fell the mighty dinosaurs?

Carolyn Gramling writes in ScienceMag that seventy million years ago animals of all sizes came to drink in a rapidly drying river in northwestern Madagascar, and never left. Tiny birds and mighty dinosaurs were entombed together in the riverbed, forming what is now a spectacular series of mass graves. Last week…

Identifying a cheaper, greener biofuel processing catalyst

Identifying a cheaper, greener biofuel processing catalyst

Many biofuels are costly to produce because the precursor product, bio-oil, must be processed before it is sent to the refinery to be turned into liquid fuel. In search of bringing that cost down, University of Illinois’ Prairie Research Institute researcher B.K. Sharma and his co-authors have identified and tested a new processing…

Treating arthritis with algae

Treating arthritis with algae

Researchers at ETH Zurich, Empa and the Norwegian research institute SINTEF are pursuing a new approach to treating arthritis. This is based on a polysaccharide, a long-chain sugar molecule, originating from brown algae. When chemically modified, this “alginate” reduces oxidative stress, has an anti-inflammatory effect…

UAE algae could produce alternative to palm oil

UAE algae could produce alternative to palm oil

Researchers at New York University Abu Dhabi (NYUAD) in collaboration with other groups have discovered that the unique genomic traits that allow local green algae to survive in a desert climate may have far-reaching potential for biotechnical applications. “The alga belongs to the Chloroidium genus…
