Microalgae are now commercially grown across a number of situations and systems. They are used in a variety of ways including functional foods for humans, as fish and animal feed, in the pharmaceutical industry, as nitrogen fixation organisms for use in agriculture, for cleaning waste water, and for concentrating industrially-valuable chemicals. This important new book provides thorough coverage of the biology, ecology and interaction with the environment of cultured microalgal species, details of the culture systems used and information about the current and potential future uses of microalgae.
