Question

What is the commercial importance of algae?

Answer 1

Commercial importance of algae:

Crude oil and Natural gasoline are the remnants of photosynthetic products of historical algae, which have been in the end modified by way of bacteria. The North Sea oil deposits are believed to have been fashioned from coccolithophore algae (class Prymnesiophyceae), and the Colorado oil shales via an alga just like Botryococcus (a inexperienced alga). these days Botryococcus produces blooms in Lake Baikal in which it releases so much oil onto the floor of the lake that it could be gathered with a special skimming equipment and used as a source of fuel. numerous corporations have grown oil-producing algae in excessive-salinity ponds and feature extracted the oil as a ability opportunity to fossil fuels.

Algae, as processed and unprocessed food, have an annual business fee of several billion greenbacks. Algal extracts are normally used in preparing foods and other products, and the direct consumption of algae has existed for hundreds of years in the diets of East Asian and Pacific Island societies. The purple alga nori, or laver (Porphyra), is the maximum important industrial food alga. In Japanalone approximately a hundred,000 hectares (247,000 acres) of shallow bays and seas are farmed. Porphyra has most important ranges in its life cycle. the first is a small, shell-boring stage that can be artificially propagated via seeding on oyster shells which can be tied to ropes or nets and set out in special marine beds for similarly improvement. The conchospores that germinate develop into the big blades of Porphyra, the second one existence degree, which can be then eliminated from the nets, washed, and pressed into sheets to dry.
