Can algae clean water?

New research explores how algae culture may hold key to cleaning up city's water bodies

Dr Alla Silkina, Department of Biosciences, has appeared in the Times of India, commenting on the possible role that algae could play in cleaning up the polluted water bodies in Cooum, India.

Alla SilkinaAlla, whose research focuses on the potential of algal biotechnology for waste remediation, said: "It is an alternative to chemical treatment of waste water.
