What is it about?

Nature has provided the earth with a diversity of living entities. We human beings have come to know through empirical learning to use some of the life forms for food, clothing, shelter, and medicine for ailments. However, majority of the life forms still exist as wild without significant utilization. One of those creatures is Microalgae that we observe existing in marine and freshwater environments. Recently, Microalgae are being considered for various kinds of utilizations such as food, medicine, and as biofuel to substitute the petroleum diesel oil. This review work tries to address the techniques of microalgae biomass drying, pretreatment, and extraction of polyunsaturated fatty acids (PUFAs) with the long-term purpose of utilizing the PUFAs in human nutrition.

Why is it important?

This work is important in that it creates awareness to readers regarding the potential benefits that might be gained from microalgae and the merits they hold to circumvent global problems such as climate change and malnutrition.

Perspectives

This work illustrates the methods and techniques used to cultivate microalgae, collect the microalgae biomass, dry it, and treat it to find the final target product. It mainly covers the techniques of biomass harvesting, drying, pretreatment, and extraction. It also compares conventional extraction methods with recently introduced, environmentally friendly extraction methods of products from microalgae biomass.
