Title : Algae: A promising solution for food, medicine and agriculture specifically use of diatomaceous earth
Abstract:
A recent research has revealed significant potential of algae as sources of food, medicine and agricultural inputs. Red algae (Spirulina) contain various vitamins, antioxidants, anticancer agents and minerals that benefit both humans and animals. Algae offer promising prospects for future medical applications. Algae also contribute to biological nitrogen fixation in the soil, which can reduce the reliance on synthetic fertilizers that are necessary to meet the food demand of a growing population. Diatomaceous earth, a dust composed of fossilized unicellular algae, has various uses as an insecticide, fungicide, plant growth regulator and protectant, as well as in cosmetics. About 10-30% of grains produced in globe as lost every year due to stored grain pests. One of the most promising alternatives to chemical insecticides is the use of diatomaceous earth (DE). Insect species, grain moisture content, temperature, humidity, methods of application, growth stage of the pest species and nature of the stored product are the chief factors which determine efficacy of diatomaceous earths. Furthermore, algae can be used to produce bio-diesel in different parts of the world. The aim of this review is to raise awareness of the potential utilization and benefits of algae (specially di-atoms) in various domains.
