An Unlikely Bond: Bad Algae Meets Bad Plastic and Falls in Love
Scientists studying cladophora algae samples taken from waters along Sleeping Bear Dunes National Lakeshore and Indiana Dunes National Park discovered that the algae had a tendency to bond to the tiny bits of plastic pollution that have flowed or were blown into the lakes. “From an investigation so far, yes, the cladophora is gathering this stuff up. So, in one way, it’s cleaning it up,” said Julie Peller, Valparaiso University organic chemistry.
Electricity Production from Seawater Using Spirulina platensis
Anew and innovative microbial fuel cell of high energy conversion efficiency (with no heat emission or corrosion problems) was formulated using nanoparticles of dry biomass Spirulina platensis microalgae. It was catalyzed by silver nanoparticles-activated carbon composite prepared by a new modified photolysis method. A high cell potential, up to 1.0 V, was obtained from this microbial fuel cell. The research was conducted by the National Institute of Oceanography and Fisheries, in Egypt.
Plant-Based Burger Patty Made from Microalgae
Sophie’s Bionutrients, a next-generation sustainable urban food production technology company in Singapore, is marketing burger patties made from microalgae. The alternative meat patty contains up to two times more protein than beef or most commercially available fish. Each patty, which weighs around 60 grams, has 25 grams of proteins — comprising all 9 essential amino acids. “By developing this burger, we hope to showcase the versatility of the microalgae protein flour that goes beyond making plant-based seafood products,” said Eugene Wang, Co-Founder & CEO of Sophie’s Bionutrients.
Light Color Study on Productivity of Dunaliella salina
In a research study at Yangzhou University, monochromatic red, blue, or the combined red and blue light illumination was applied to Dunaliella salina culture to study the effects of illumination on the growth and biocomponents productivity of the microalga D. salina. The monochromatic blue light (peak wavelength, 455 nm) did not significantly enhance D. salina growth but boosted the cellular contents of lipid, protein, and carbohydrate.
India: A Potential Algal Protein Powerhouse
India could become a major foundation for the global algal protein industry, a fast-growing sector in the sustainable protein supply chain, according to a new analysis. The report, released by the Good Food Institute India (GFI India), details the country’s unique opportunity to tap into its cohort of homegrown microalgae producers and optimal coastline environment to meet the rising demand for climate-resilient food solutions.
