Optimizing CO2 efficiency and luminescence in PBRs

Researchers at Heriot-Watt University, in Edinburgh, have published a report on their study of microalgae cultivated in photobioreactors at different CO2 concentrations and luminescent conditions. Their report is published in Elsevier’s Biomass and Bioenergy, Volume 85, February 2016…

Alaska shellfish growers learn seaweed farming

Alaska shellfish growers learn seaweed farming

SitNews, of Ketchikan, Alaska, reports that with edible kelp driving a $5 billion industry worldwide, Alaska’s shellfish farmers are exploring seaweed as the next step in their small industry. About 40 farmers learned about kelp growing methods, markets, biology, and state programs to expand mariculture during a workshop…

Cyanobacteria efficient at “harvesting” light

Cyanobacteria efficient at “harvesting” light

Cyanobacteria, also known as blue-green algae, have an ingenious system to prepare themselves for the coming daylight when it is dark by setting up a large “antenna.” This antenna helps them capture light energy in an efficient way, while also providing protection against damage to the photosynthesis mechanism of the…

Did green plants really come from terrestrial algae?

Did green plants really come from terrestrial algae?

Plant biologists agree that it all began with green algae. At some point in our planet’s history, the common ancestor of trees, ferns, and flowers developed an alternating life cycle — presumably allowing their offspring to float inland and conquer Earth. But Danish scientists have just suggested, in Trends in Plant Science, that some…

Coal dust + algae = Coalgae

Coal dust + algae = Coalgae

Heather Dugmore writes for BDlive that a new fuel, Coalgae – produced from a combination of waste coal dust and algae – could save South Africa up to 40% of its crude oil imports. Professor Ben Zeelie and his team at Nelson Mandela Metropolitan University (NMMU) combined coal dust with algae to form…

IIASA study shows algae’s potential as a livestock feed

IIASA study shows algae’s potential as a livestock feed

A new study from International Institute for Applied Systems Analysis (IIASA) researchers suggests that algae could become an important feed for livestock that could potentially contribute to a major cut in greenhouse gas emissions over the next 80 years. The study, published in the open-access journal…

Culturing agent agar hit by seaweed shortage

Culturing agent agar hit by seaweed shortage

Ewen Callaway writes in the jounal Nature that restrictions on harvests and exports of Gelidium seaweed in Morocco have affected the global supply of the lab reagent agar. Microbiology’s most important reagent is in short supply, with potential consequences for research, public health and clinical… [Read the full story]
