Title : The Current Status and Future Scope of Algae in Food, Medicine and in Sustainable Agriculture under climate change scenario
Algae are members of phytoplankton belong to Thalophyta and aquatic in nature. Their role in ecosystem remained hidden. Now in new research era, Researchers found a significant role of Algae as a food, medicine and in agriculture. Red algae (Spirulina) have many vitamins, antioxidants, anticancer and mineral for human and animals. In Japan and other countries, many dishes are prepared from algae. A lot of potential is present in algae for future medicine. Algae fix the biological nitrogen fixation in soil. Use of synthetic fertilizers is inevitable in agriculture as a result to fulfill the demand of a country for their growing population. So, the priority to supply food in an eco-friendly manner we will have to lessen the impact of synthetic fertilizers in the agriculture. Use of bio-fertilizer through algae can be effective for farmers in this situation to increase productivity. Bio-fertilizers enhance plant growth and development by adding nutrients through natural biological processes.It has been claimed that extracts of Kappaphycus alvarezii and Gracilaria edulis (Algae) can improve nutrient absorption and utilization in the crops. Diatomaceous earth is dust composed of unicellular algae fossilized bodies used as insecticides, fungicide, plant growth regulator and protectant. This diatomaceous earth is also used in cosmetics. Bio-diesel is also produced from algae in different parts of globe. In this context, the aim of this review is to bring awareness about the potential of algae and its beneficial impacts.
