Light and temperature key to cultivation of a special microalga

The world is searching for sustainable solutions for future food production, and microalgae appear to have the potential to play a crucial role. The microalga Nannochloropsis oceanica is particularly interesting because it ...

Vanishing sea ice threatens polar food chain

Rapid sea ice loss and ocean acidification from climate change are altering the growth and nutritional value of microscopic algae. These algae are an essential food source for fish, krill, and other small organisms that sustain ...

Insect frass becomes food for protein-rich microalgae

As the demand for protein-rich food increases with population growth and rising awareness of nutrition and health, traditional animal and plant-based protein sources that require arable land or freshwater put significant ...

Researchers bring 60-year-old dormant algae cells to life

New research at Åbo Akademi University, Finland, has managed to circumvent previous challenges in finding out how microalgae adapt to global warming by studying up to 60-year-old microalgae cells from the Archipelago Sea. ...

A microalgae–material hybrid promotes carbon neutrality

Microalgae, including cyanobacteria and green algae, represent the most important biological systems for producing biomass and high-value products. It is estimated that microalgae can fix about 90 billion tons of carbon dioxide ...

Nordic microalgae: Potential superstars in the green transition

The carbon dioxide emissions of the growing human population have a massive impact on the climate. While many are seeking solutions, researchers in Umeå, Sweden, might have found one right in front of their houses: Nordic ...

Shining a light on tiny, solar-powered animals

Animals and plants need energy. Some animals get energy by eating other animals, and many plants harvest the energy in sunlight through photosynthesis. However, in the ocean, there exists a remarkable group of small, worm-like ...

Microphyte

Microphytes or microalgae are microscopic algae, typically found in freshwater and marine systems. 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 hundreds of micrometers. Unlike higher plants, microalgae do not have roots, stems and leaves. Microalgae, capable of performing photosynthesis, are important for life on earth; they produce approximately half of the atmospheric oxygen and use simultaneously the greenhouse gas carbon dioxide to grow photoautotrophically.

The biodiversity of microalgae is enormous and they represent an almost untapped resource. It has been estimated that about 200,000-800,000 species exist of which about 35,000 species are described. Over 15,000 novel compounds originating from algal biomass have been chemically determined (Cardozo et al. 2007). Most of these microalgae species produce unique products like carotenoids, antioxidants, fatty acids, enzymes, polymers, peptides, toxins and sterols.
