Abstract: A novel variety of the unicellular green algae Chlamydomonas reinhardtii, named ‘DG8-108’, was created by exposing wild-type C. reinhardtii to ?-radiation exposure. This new and distinct alga variety demonstrates nearly double the biomass and photosynthetic productivity of wild-type C. reinhardtii under both optimal and stress conditions.

Abstract: A novel variety of the microalga Haematococcus pluvialis (syn. H. lacustris), named ‘KAS1601-WG7’ is primarily characterized by a yellow and motile cell body during propagation transitioning to a red and motile cell body under pigment accumulation conditions. The cells contain negligible chlorophyll. It has fast growth under heterotrophic cultivation for ease of propagation and shows high carotenogenesis under dark heterotrophic cultivation. The highly pigmented non-encysted cells are attractive for ease of extraction and for high digestibility, including as whole cells, to release a mixture of oils, proteins, pigments, and other components desirable for use in food, feeds, cosmetics and dietary supplements, and excellent storage as biomass.
Abstract: A new and distinct cultivar of the red macroalgae Asparagopsis taxiformis named “Icarus,” characterized by significantly smaller internal branching angles, a smaller form when aggregated in tumble culture, and a dark red pigmentation. New branches of this macroalgae are generated prolifically at higher temperatures than wild-type A. taxiformis, making “Icarus” well-suited for commercial growth, e.g., when there is a risk of extreme heat events, in cases of needing to lower the cost of cooling cultivars, or other such conditions.
