“…Studies have shown that spirulina can reduce inflammation in the body, which is linked to many chronic diseases such as heart disease, diabetes and cancer. The antiinflammatory effects of Spirulina may be due to its high content of phycocyanin, a pigment that has been shown to reduce oxidative stress and inflammation in the body [8,9]. Spirulina contains betaine, polyphenols and FC protein.…”

“…These can be naturally generated in situ (endogenous antioxidants) or supplied externally through food (exogenous antioxidants) [5,6]. Spirulina may protect the activity of cellular antioxidant enzymes, including GPX, seleniumdependent glutathione peroxidase and oxidized glutathione reductase [4,7,8]. There is a significant amount of scientific evidence regarding the benefits of spirulina and a strong social need to contribute to conventional treatments that already exist; consequently, this work aims to review the pharmacological activity of the different species of spirulina related to the hepatoprotective, antioxidant and anticancer effects.…”

Since the older days, spirulina has been consumed as a vital food supplement derived from algae. The properties of this alga, such as anticancer, antioxidant and hepatoprotective, have great significance in enhancing the quality of life and contributing to better health. The affliction of liver diseases and cancer is widespread among humanity, causing significant health issues. Thus, the importance of the current work is evident. The purpose was to assess the pharmacological properties of spirulina species concerning their capacity to guard the liver, counteract oxidation and combat cancer. In order to find the most comprehensive information, an intensive hunt was launched on various online databases such as Google Scholar, Scopus, PubMed and Medline. The focus was only on complete experimental and clinical works that surfaced between 2000 and 2019. 2064 related articles were found, of which 58 met the requirements of the present work; they were analysed by documentary analysis and grouped into clusters according to their pharmacognosy properties. According to the articles reviewed, spirulina possesses abundant nutraceutical components and holds promise as an anti-inflammatory, hepatoprotective, antioxidant, antimutagenic, cytotoxic, anticancer and apoptotic agent. RezumatSpirulina a fost folosită ca și supliment alimentar esențial încă din cele mai vechi timpuri. Afecțiunile hepatice și oncologice sunt larg răspândite și provoacă grave probleme de sănătate. Scopul prezentului studiu a fost evaluarea proprietăților farmacologice ale speciilor de spirulină, capacitatea lor hepatoprotectoare, antioxidantă și antineoplazică, consultând diferite baze de date (Google Scholar, Scopus, PubMed și Medline). Accentul a fost pus doar pe lucrările experimentale și clinice complete apărute între anii 2000 și 2019, astfel au fost găsite 2064 de articole conexe, dintre care doar 58 au îndeplinit criteriile de includere. Conform articolelor analizate, spirulina posedă abundente componente nutraceutice și aduce beneficii terapeutice ca agent antiinflamator, hepatoprotector, antioxidant, antimutagenic, citotoxic, anticancerigen și apoptotic.

“…However, the challenges of extraction and purification, including their complexity, low efficiency, and high costs, have significantly restricted its expansion into other domains. Sphingomonas (Carmona et al 2023;Baudoin et al 2023;Lu et al 2023;Nsengiyumva and Alexandridis 2022). Challenges, such as high viscosity, residual bacterial cells, carotenoids, and protein complexation, pose critical obstacles to the purification and extraction of welan gum, making the purification of the final product difficult; in particular, these challenges complicate welan gum purification and extraction in terms of impurity removal, product purification, and drying, which account for approximately 50% of the total production costs of welan gum (Kaur et al 2014).…”

Welan gum, a natural polysaccharide produced by Sphingomonas sp. ATCC 31555, has attracted considerable attention in the scientific community due to its desirable properties. However, challenges, such as high viscosity, residual bacterial cells, carotenoids, and protein complexation, hinder the widespread application of welan gum. In this study, we established a method for the extraction and purification of welan gum using a synergistic approach with lysozyme and alkaline protease. Lysozyme hydrolysis conditions were optimized by applying response surface methodology, and the best results for bacterial cell removal were achieved at 11 000 U/g, 44 °C, and pH 9 after 3 h of treatment. Subsequently, we evaluated protein hydrolysis through computer simulation and identified alkaline protease as the most suitable enzyme. Through experimental investigations, we found that the optimal conditions for alkaline protease hydrolysis were 7500 U/g, 50 °C, pH 10, and 600 rpm. These conditions resulted in a sugar recovery rate of 76.1%, carotenoid removal rate of 89.5%, bacterial removal rate of 95.2%, and protein removal rate of 87.3% after 3 h of hydrolysis. The purified welan gum exhibited high transparency and purity. Structural characterization and antioxidant activity evaluation revealed that enzymatically purified welan gum has potential application prospects. Our study provides valuable insights into the optimal method for the enzymatic extraction and purification of welan gum. Such a method is conducive to the development of the multiple potential applications of welan gum. Key points• A novel process for the synergistic purification of welan gum using lysozyme and alkaline protease was established.• In silico virtual digestion was employed to select the purification enzyme.• Welan gum with high transparency and purity was obtained.
