Seaweed Proteins: A Step towards Sustainability?
Pereira, Leonel; Cotas, João; Gonçalves, Ana MartaThis review delves into the burgeoning field of seaweed proteins as promising alternative sources of protein. With global demand escalating and concerns over traditional protein sources' sustainability and ethics, seaweed emerges as a viable solution, offering a high protein content and minimal environmental impacts. Exploring the nutritional composition, extraction methods, functional properties, and potential...
Seaweeds as Nutraceutical Elements and Drugs for Diabetes Mellitus: Future Pers...
Cotas, João; Lomartire, Silvia; Pereira, Leonel; Valado, Ana; Marques, J.; Gonçalves, Ana MartaDiabetes mellitus is a chronic metabolic condition marked by high blood glucose levels caused by inadequate insulin synthesis or poor insulin use. This condition affects millions of individuals worldwide and is linked to a variety of consequences, including cardiovascular disease, neuropathy, nephropathy, and retinopathy. Diabetes therapy now focuses on controlling blood glucose levels through lifestyle changes...
Antioxidant and Antidiabetic Activity of Algae
Abo-Shady, Atef Mohamed; Gheda, Saly Farouk; Ismail, Gehan Ahmed; Cotas, João; Pereira, Leonel; Abdel-Karim, Omnia HamdyCurrently, algae arouse a growing interest in the pharmaceutical and cosmetic area due to the fact that they have a great diversity of bioactive compounds with the potential for pharmacological and nutraceutical applications. Due to lifestyle modifications brought on by rapid urbanization, diabetes mellitus, a metabolic illness, is the third largest cause of death globally. The hunt for an efficient natural-bas...
Therapeutic Potential of Polyphenols and Other Micronutrients of Marine Origin
Pereira, Leonel; Cotas, JoãoPolyphenols are compounds found in various plants and foods, known for their antioxidant and anti-inflammatory properties. Recently, researchers have been exploring the therapeutic potential of marine polyphenols and other minor nutrients that are found in algae, fish and crustaceans. These compounds have unique chemical structures and exhibit diverse biological properties, including anti-inflammatory, antioxid...
Seaweed Polysaccharides in Agriculture: A Next Step towards Sustainability
Mamede, Mariana; Cotas, João; Bahcevandziev, Kiril; Pereira, LeonelThe seaweed-based biostimulants available in the market are proven to achieve better results than synthetic commercial fertilizers in plant growth parameters. There are many compounds present in seaweeds that are responsible for the plant bioactivities. Seaweed polysaccharides, such as agar, alginate, and carrageenan, make up most of the seaweed biomass and are proven to achieve excellent results in agricultura...
Different Chondrus crispus Aquaculture Methods and Carrageenan Extraction
Tanoeiro, João Rui; Fortunato, Duarte; Cotas, João; Morais, Tiago; Afonso, Clélia; Pereira, LeonelWith the notable scarcity of Chondrus crispus on the Portuguese coast, and interest in exploiting compounds such as carrageenan, this study focuses on investigating different aquaculture methods and recording the yield of carrageenan from specimens grown by different methods. We compare the growth of Chondrus crispus in aquaculture using Free Floating, Cages, Attempted Fixation on Rock, and Fixed Line similar t...
A Possible Synergistic Approach: Case Study of Saccharina latissima Extract and...
Pacheco, Diana; Cotas, João; Pereira, Leonel; Bahcevandziev, KirilNowadays, the exponential expansion in human population has resulted in the massification of intensive agricultural practices, with crop yield and sustainability being one of the most pressing challenges. Therefore, there was a need for new and natural fertilizers and pesticides, which has become a popular agricultural trend nowadays. Therefore, there was an increased interest to apply seaweed and bacterial ext...
Use of Chlorella vulgaris and Ulva lactuca as Biostimulant on Lettuce
Ammaturo, Chiara; Pacheco, Diana; Cotas, João; Formisano, Luigi; Ciriello, Michele; Pereira, Leonel; Bahcevandziev, KirilThe important purpose of this work is to evaluate the biostimulant activity of the algae Chlorella vulgaris and Ulva lactuca extracts on the crop plants Lactuca sativa, to compare the effect of these two green algae on plant growth and development as a part of a sustainable plant production method and show that these extracts can be a promissory source for replacing chemical fertilization. The study faces all t...

A Comparative Study of the Fatty Acids and Monosaccharides of Wild and Cultivat...
García-Poza, Sara; Morais, Tiago; Leandro, Adriana; Cotas, João; Marques, João Carlos; Pereira, Leonel; Gonçalves, Ana M. M.There is a need to find new possible raw food sources with interesting nutritional values. One of the most unexploited sources are seaweeds. Thus, Ulva sp. is a green edible seaweed that shows a high growth rate in nature and can support drastic abiotic changes, such as temperature and salinity. This work aims to determine the main nutritional compounds, fatty acids (FAs) and monosaccharides profiles of Ulva sp...
