Rescue for Sardines and Anchovies: Produce DHA through biotechnology using microalgae

19-Sep-2019

Bioprocess engineers Anja Lemoine and Stefan Junne are researching substitutes for fishmeal and fish oil in aquacultures by fermenting waste into different acids and then feeding these to microalgae. While others stockpile food, Lemoine and Junne hoard leftovers in the fridges of the Chair of ...

Secrets of fluorescent microalgae could lead to super-efficient solar cells

13-May-2019

Tiny light-emitting microalgae, found in the ocean, could hold the secret to the next generation of organic solar cells, according to new research carried out at the Universities of Birmingham and Utrecht. Microalgae are probably the oldest surviving living organisms on the planet. They have ...

Harnessing energy from algae

An enzyme that could help accelerate biofuel production

21-Aug-2018

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 ...

Questioning conventional understanding of antifreeze proteins

Scientists describe new phenomenon possibly expanding application

02-Aug-2018

Scientists have discovered that an ice-binding protein (fcIBP) from the sea ice microalga does not fit in the conventional classification of ice-binding proteins, suggesting unknown mechanisms behind its antifreeze property. This finding could lead to a broader application of the antifreeze ...

Diatom ooze sediments are a large marine mercury sink

Sediments reveal mercury pollution in Antarctica since the beginning of the industrial period

30-Jul-2018

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. ...

Toxicity of carbon and silicon nanotubes and carbon nanofibers

20-Jul-2018

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 ...

Photosynthetic microalgae as biocatalysts

The biocatalytic production of chemicals should become considerably more sustainable

06-Mar-2018

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 ...

Genome sequence of fuel-producing alga announced

12-May-2017

The genome of the fuel-producing green microalga Botryococcus braunii has been sequenced by a team of researchers led by a group at Texas A&M AgriLife Research. The report comes after almost seven years of research, according to Dr. Tim Devarenne, AgriLife Research biochemist and principal ...

Fast, low energy, and continuous biofuel extraction from microalgae

03-May-2017

As an alternative to liquid fossil fuels, biodiesel extracted from microalgae is an increasingly important part of the bioenergy field. While it releases a similar amount of CO2 as petroleum when burned, theCO2 released from biodiesel is that which has recently been removed from the atmosphere ...

Algal residue - an alternative carbon resource for pharmaceuticals and polyesters

18-Apr-2017

Microalgae have received much attention in biomass production due to many strains having a high biomass productivity per unit time and per unit area. Algae produce high levels of oil as well as carbohydrates, occurring mainly in the form of starch. They can survive in unfavorable, nutrient ...
