Vitamin B12 adaptability in Antarctic algae has implications for climate change
Vitamin B12 deficiency in people can cause a slew of health problems and even become fatal. Until now, the same deficiencies were thought to impact certain types of algae, as well. A new study led by former MIT CBIOMES postdoc Deepa Rao examined the algae Phaeocystis antarctica’s (P. antarctica) exposure to a matrix of iron and vitamin B12 conditions. Results show that this algae can survive without B12, something that computer analysis of genome sequences had incorrectly indicated.
