Making protein 'superfood' from marine algae

Marine microalgae-based cellular agriculture is a promising new way to sustainably produce plant-based 'meat' and healthy 'superfoods' for the future.

Study discovers how some single-cell organisms control microbiomes

Large swaths of single-celled eukaryotes, non-bacterial single-cell organisms like microalgae, fungi or mold, can control microbiomes (a collection of tiny microbes, mostly bacteria) by secreting unusual small molecules around ...

Boost to develop microalgae into health foods

Dietary supplementation of fatty acids produced from microalgae have wide-reaching health benefits for humans, including the ability to reduce obesity, diabetes and fatty liver disease, preventing hair loss, and assisting ...

Coral's resilience to warming may depend on iron

How well corals respond to climate change could depend in part on the already scarce amount of iron available in their environment, according to a new study led by Penn State researchers. The study reveals that the combination ...

Microalgae food for honey bees

A microscopic algae ("microalgae") could provide a complete and sustainably sourced supplemental diet to boost the robustness of managed honey bees, according to research just published by Agricultural Research Service (ARS) ...

Microphyte

Microphytes or microalgae are microscopic algae, typically found in freshwater and marine systems. They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a few micrometers (µm) to a few hundreds of micrometers. Unlike higher plants, microalgae do not have roots, stems and leaves. Microalgae, capable of performing photosynthesis, are important for life on earth; they produce approximately half of the atmospheric oxygen and use simultaneously the greenhouse gas carbon dioxide to grow photoautotrophically.

The biodiversity of microalgae is enormous and they represent an almost untapped resource. It has been estimated that about 200,000-800,000 species exist of which about 35,000 species are described. Over 15,000 novel compounds originating from algal biomass have been chemically determined (Cardozo et al. 2007). Most of these microalgae species produce unique products like carotenoids, antioxidants, fatty acids, enzymes, polymers, peptides, toxins and sterols.
