alkaliphiles is large, their metabolites have not yet been extensively analyzed and
exploited. This is expected to come in the years ahead. So far, the focus of interests in
metabolites from alkaliphiles falls into categories such as organic acids, ingredients
for foodstuffs and cosmetics, antibiotics, and substances which modify properties
of other materials used in industry. This chapter deals with biotechnologically
important metabolites of alkaliphiles including compatible solutes, biosurfactants,
siderophores, carotenoids, exopolysaccharides, and antimicrobial agents. It also
covers the promising potential of alkaliphiles as sources of bioplastic raw materials.
Moreover, an overview of the patent literature related to alkaliphiles is highlighted.
