Ana Feeds Our World, Part 3

Algae can be such lively little critters that some scientists consider them animals. Many can swim, such as dinoflagellates that have little whip-like structures called flagella which pull or push them through the water. Some algae squish part of their body forwards and crawl along solid surfaces…

The effect of respiration on photosynthesis

Scientists have long studied which of the three primary photosynthetic eukaryotes (red algae, green algae, and glaucophytes) came into existence first — to unravel the biological mystery of algae evolution by analyzing their genetic information. Despite learning that the structure of cyanelles, an organelle unique…

1.6 Billion-year-old red algae fossils discovered

Scientists at the Swedish Museum of Natural History have found fossils of 1.6 billion-year-old probable red algae. The spectacular finds, publishing on March 14, 2017, in the open access journal PLOS Biology, indicate that advanced multicellular life evolved much earlier than previously thought…

New Wave Foods’ sustainable shrimp from red algae

San Francisco biotech startup New Wave Foods aims to address the impact of overfishing, bycatch, water pollution, slave labor, an animal death toll in the trillions, and other ills of our unsustainable lust for shrimp…with red algae. In the lab, New Wave Foods has engineered a product with the same taste, texture, and look…

Can seaweed cure food allergies?

Edible seaweed are low-calorie and packed with nutrients. Now scientists have found that a type of commercial red macroalgae could help counteract food allergies. They report their findings, using mice, in ACS’ Journal of Agricultural and Food Chemistry (May 17, 2016). Food allergies are a major global health issue that can…

Brown algae most studied for use in feed

Emmy Koeleman writes in All About Feed & Dairy Global about a review in the Journal of Animal Feed Science and Technology that looked at the different seaweeds available and how they can be used for ruminants, pigs, poultry and rabbits. Seaweeds are valuable alternative feeds for livestock…

Exploring red algae for economic benefits

James Konstantin Galvez writes in the Manila Times that red algae, or lumut, which many people there consider insignificant, offers huge economic benefits as a source of food and components for industrial products, according to a new study by the University of the Philippines-Marine Science Institute (UPMSI)…

Red algae fermentation for ethanol

Business Korea reports that a Korean research team headed by Choi In-gul, a professor at the Department of Biotechnology at Korea University, has successfully defined the fermentation process of red algae and found a clue to making ethanol…
