Description Marine algae are macroscopIC plants constituting an important
marine living renewable resource. They are used as human food, livestock
feed and fertilizer for land plants in many parts of the world besides having
the prime importance of being the only source for the production of agar,
carrageenan and alginates. These phytochemicals are extensively used in
various industries such as food , confectionery, textile, pharmaceutical,
cosmetics, dairy, liquor, canning, paint, varnish, paper etc. mostly as
gelling, stabilising and thickening agents and have an estimated billion
dollar global market (Zilinskas and Lundin, 1993). A summary of sources,
chemical composition, properties and important applications of these
phytochemicals given by Nambisan (1998) is presented in Table 1.
The commercial exploitation of seaweeds is going on since 1966 and
the export of economically important seaweeds such as Gelidiella,
Gracilaria and Sargassum was banned by the Govt. of India in 1975 as agar
and algin industries were started in India by 1970. In recent years many
industries producing these phytochemicals have come up in India but as yet
the production do not meet the demand. The annual demands of raw
materials by Indian seaweed based industries are 2000 tonnes and 12,000
tonnes (dry weight) of agarophytes and alginophytes respectively. Annually,
about 60 tonnes of agar and 500 tonnes of alginates are produced. In India
carrageenan is not yet produced. However its demand is nearly 200 tonnes
per year. Since the indigenous production of agar and alginates is unable
to meet the increasing demand, India is importing about 10-12 tonnes of
pharmaceutical grade agar, 35 tonnes of algi nates and 140 tonnes of
carrageenan costing foreign exchange of about Rs.10 crores (Zaidi et al.,
1999) This is mainly due to the paucity of raw materials particularly agar
yielding seaweeds.
