Abstract(s)
Microalgae and cyanobacteria are photosynthetic and unicellular organisms that contain considerable amounts
of proteins, lipids, carbohydrates, and polyunsaturated fatty acids, among others, with applications in the
cosmetic, pharmaceutical, and food industries. These microorganisms can accumulate protein up to 70 % of total
biomass depending on the microalgal strain, hence they have been regarded as an alternative protein source for
the future. Microalgal proteins have important applications such as emulsifying, foaming, and gelation prop erties, which are important for the determination of quality and texture of foods. Some microalgal peptides
possess important bioactivity with many health-benefit effects. Therefore, to maximize the production of proteins
from microalgae and cyanobacteria, many protein extraction procedures have been studied to increase the
economic return. They have been tested towards higher protein yields at low energy cost, the preservation of
protein native properties, and lower cell debris. This later is fundamental to facilitate the subsequent purification
processes so that the overall cost can be reduced. The aim of this work is to review some cell disruption processes
for the extraction of protein from microalgae and cyanobacteria, considering that this step is crucial for the
overall process due to the high rigidness of microalgal cell covering, which can hamper the release of proteins. It
also aims at reviewing the purification techniques after cellular disruption, from conventional to more recent
approaches, and finally addresses the antioxidant, antidiabetic, antihypertensive, antibacterial and other
bioactive properties of microalgal protein hydrolysates and peptides.
