New Zealand looking to develop sea lettuce

Skara Bohny reports in Stuff.co.nz that New Zealand’s Cawthron Institute is receiving funding as part of the High-Value Nutrition’s (HVN) National Science Challenge to develop a Māori taonga species of seaweed closely related to Japanese nori into a high-value product. Cawthron is working…

A cheaper, cleaner way to grow biodiesel producing microalgae?

A cheaper, cleaner way to grow biodiesel producing microalgae?

Gerard de Souza reports for the Hindustan Times that researchers at the CSIR-National Institute of Oceanography Goa (India) have found a cleaner, cheaper method to grow biodiesel producing microalgae — one that uses wastewater…

Researching conditions leading to HABs

Researching conditions leading to HABs

When there is a combination of population increase, wastewater discharge, agricultural fertilization, and climate change, the cocktail is detrimental to humans and animals. This harmful cocktail produces harmful algal blooms, and many of these are toxic to humans and wildlife. Wayne Wurtsbaugh, Professor Emeritus…

Protein factor increases yield of biofuel precursor

Protein factor increases yield of biofuel precursor

As an alternative to traditional fossil fuels, biofuels represent a more environmentally friendly and sustainable fuel source. Plant or animal fats can be converted to biofuels through a process called transesterification. In particular, the storage molecule triacylglycerol (TAG), found in microscopic algae…

Exploring land plant evolution

Exploring land plant evolution

How did plants make the evolutionary jump from water to land? Scientists think that green algae are their water-living ancestors, but we are not sure how the transition to land plants happened. However, new research from Michigan State University, and published in the journal eLife, presents evidence…

Algae byproduct CARS shows potential as cattle feed

Algae byproduct CARS shows potential as cattle feed

John Maday writes in Drovers.com that, as algae emerges as a commercial source for omega-3 fatty acids for human and animal foods, the process for extracting those fatty acids — leaving the byproduct condensed algal residue solubles (CARS) — could replace some grain in cattle feedlot rations. With the CARS…
