Microalgae have long been recognised for their nutritional value and high protein contents. With the increasing demand for “vegan protein” and concerns for global food security, microalgal protein is finding renewed interest. Microalgae are highly productive and can be grown without competing for arable land or freshwater resources. Most microalgal protein contains all essential amino acids and is hence more suitable as a meat replacement than any other plant protein. Microalgal products are also readily suitable for cosmetic and nutraceutical applications due to their significant health benefits. This chapter provides an overview of the use of various protein-rich microalgae in food, feed, nutraceuticals, and cosmetics. The latest technical advances in protein extraction from microalgae are presented, together with an overview of current knowledge on bioavailability and digestibility of microalgal proteins.

With increasing demand for meat and dairy products but limited capacity for expanding crop production, there is need for alternative feed sources. Careful selection of seaweed species based on nutrient content and profiles could allow successful use of seaweed as an alternative protein supplement in animal feeds. This chapter introduces seaweed as a potential alternative protein supplement in animal feeds as well as current challenges in its use.

This chapter reviews effects of supplemental full- or de-fatted microalgal biomass in diets for broiler chickens, laying hens, and other types of poultry on their production performance, meat and egg qualities, nutrient metabolism, and molecular responses. Different sources of microalgal biomass have shown excellent potential to replace a good amount of SBM and(or) corn without adverse effects. Meanwhile, microalgae are used to enrich chicken meat and eggs with n3-polyunsaturated fatty acids and bioactive phytochemicals for adding human health-promoting values to these animal products. The dual application of microalgae for producing biofuels and replacing conventional feed protein stands as propitious mediator to reshape the junction between intensifying animal agriculture and meeting the global needs for energy, food, and environmental sustainability.

Macroalgae and microalgae, including cyanobacteria, are primarily photosynthetic organisms grown for the production of renewable biomass for foods, feedstocks, and high-value specialty chemicals. While there are differences in cultivating and harvesting macro- and microalgae due to scale, many of the same downstream techniques can be used for processing algal biomass. This chapter will outline various developments in processing technologies used for the treatment of algal biomass with discussion of scalability, cost, time, and efficacy. Topics will cover methods for harvesting and dewatering algae, drying algal biomass, biomass disruption, and nutrient recovery, including case studies with lessons learned. The final section presents biomass applications and product considerations. While there is no universally-adopted approach for processing algal biomass, these studies provide the foundation for making informed decisions, considering the unique properties of the algae and the integrity of the desired end products.

Expanding markets for microalgae and macroalgae products have led to increased development of commercial farming operations. While microalgae and macroalgae, or seaweed, have historically been harvested in many parts of globe, more recent developments seek to improve productivity, decrease production costs, increase scale, and mitigate environmental impacts of cultivation. This chapter highlights some of those recent developments and identifies future focus areas for research and development.

Red seaweeds are a major industrial source of agar and carrageenan. They also contain high amounts of other polysaccharides and higher amounts of proteins than brown seaweeds. Some species of red seaweed also contain polyphenols with antioxidant activities as well as being a source of carotenoids and phycobiliproteins. However, there are currently no commercial-scale methods for extracting those bioactive compounds. This chapter provides an overview of various methods for extracting all these functional compounds from red seaweeds. Whereas the main emphasis is on the extractions of proteins, extractions of polysaccharides (carrageenan and agar) and antioxidants (phenolic compounds) are covered. Multi-extraction approaches for extractions of bioactive compounds from red seaweeds are also described.

The rapid expansion of aquaculture industry is severely restricted by the shortage of key feed ingredients such as fishmeal and fish oil. Application of marine plants (macro and microalgae) as dietary ingredients could potentially overcome the limitation of key feed ingredients used in aquafeed. Macroalgae and microalgae contain considerable amounts of protein, omega-3 long chain polyunsaturated fatty acids-enriched lipid and different bioactive functional compounds. Feeding macroalgae and microalgae meal has been proved to improve growth, overall health, reproductive performance, and fillet quality of fish. This chapter summarizes the current knowledge of the use of macro and microalgae in aquafeed and their effects on overall fish performance.

Macroalgae are a promising source of nutritional ingredients including proteins, polysaccharides and minerals. The need to increase animal and feed production has increased interest in macroalgae as underutilised resources with promising applications as alternative animal feeds. This chapter summarizes the nutritional attributes of macroalgae in terms of macro and micronutrients as a source of protein and other compounds in pig nutrition. The benefits of macroalgae or macroalgal derived extracts in feed are discussed together with future trends and challenges in the development of effective feed formulations.
