6.1 Introduction
The term seaweed typically refers to cryptograms that grow in seawater and do not
bloom. They include green, brown, and red algae, which are visible to the unaided
eye and survive by attaching to other objects.
Because water is the chief setting for their growth, they differ considerably from
land organisms in their development temperatures and photosynthetic properties.
Even seaweeds belonging to the same group often possess unique biogenic substances and metabolic characteristics. Seaweeds are a promising source of energy and
bioactive substances that will make them key, alongside plankton, in resolving future
food issues. Recently, research has been conducted toward applying marine
biotechnology—an area where notable advancements have been made—to seaweeds
to develop useful breeds or produce useful substances. Despite these efforts, however,
the biochemical properties of green, brown, red algae differ due to their belonging to
