“…In this study, significant levels of antimicrobial effects were observed in macroalgae extracts. Similar results in this study were reported by Jing-Wen and Wei-ci 1984, Yegdaneh et al 2016, Zouaoui and Ghalem 2017and Negara et al 2020 have also been determined.…”

In the present study, the seaweeds belong to Phaeophyaceae (Cystoseira elegans Sauvageau 1912, Cystoseira amentacea (C.Agardh) Bory 1832, Padina crassa Yamada 1931) and Florideophyceae (Corallina elongata J.Ellis & Solander 1786) collected from nearby Iskenderun-Turkey of Mediterranean Sea were detected for their antimicrobial activities against seven bacterial strains (Escherichia coli ATCC 35218, Bacillus cereus NRRL B-371, Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, Klebsiella pneumoniae ATCC 13883, Salmonella typhimurium ATCC 14028, Proteus vulgaris RSKK 96029). The antimicrobial activities were expressed as minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs). According to the results obtained from MICs and MBCs values of the extracts on pathogenic microorganisms were between 0.78 to 50 mg/mL. The lowest MICs and MBCs values were recorded for C. elegans extract against B. cereus with a MIC value of 0.78 mg/mL. These results suggest that secondary metabolites of brown and red algae are important sources that could be used as broad spectrum of biological and pharmaceutical activities.

“…U. lactuca methanol extract was not effective in mycelium growth inhibition of F. oxysporum and M. phaseolina as shown in table 3 and 4 and these results disagree with Zouaoui & Ghalem [23] who reported that methanol extract obtained from U. lactuca showed antifungal activity for Candida albicans. There is no significant difference in the inhibitory effect between positive control miconazole and U. lactuca hexane extract at 4.91 mg/ml concentration.…”

Seaweeds are naturally rich with biological active metabolites that could be promising to be used in the biological control. The present study was conducted to evaluate the antifungal potentiality of metabolites extracted from Ulva fasciata, Ulva lactuca and Cladophora sericea; against Macrophomina phaseolina (Tassi) Goid. and Fusarium oxysporum Schltdl. Four organic solvents hexane, chloroform, acetone and methanol were used for extraction of seaweeds metabolites to assay their biological efficiency on mycelium growth reduction of two candidate soil borne fungal pathogens on potato dextrose agar medium. The highest percentage of F. oxysporum and M. phaseolina growth reduction was observed by acetone extract of U. fasciata and methanol extract of C. sericea. The highest inhibition against M. phaseolina reached up to 28.97% by U. fasciata acetone extract and 24.77% by C. sericea methanol extract. The highest percentage of mycelial growth inhibition of F. oxysporum was observed by U. fasciata acetone extract (23.58%) and C. sericea methanol extract (17.01%). Analysis of acetone extract of U. fasciata by gas chromatography mass spectrophotometer GC/MS revealed the presence of some organic compounds with antifungal properties such as Phenol, 2,2'-methylenebis[6-(1,1-dimethylethyl)-4-methyl-, Di-n-octyl phthalate, 1,2-Benzenedicarboxylic acid, diisodecyl ester, Didecyl phthalate, Phthalic acid, bis (7-methyloctyl) ester, gamma Sitosterol, Cholest-5-en-3-ol, 24-propylidene-, (3. beta.) and Cyclononasiloxane, octadecamethyl-. The results suggest that the studied algal species can be used as potential bio-agent source in biological control of soil borne phytopathogenic fungi.

“…As secondary metabolites, phlorotannins play a series of recognized roles in the cell, such as antiherbivory defense, antifouling activity, and UV protectants [15]. Marine phenolics show several biological activities [16], such as antioxidants [10,17], antiinflammation [18][19][20], antimicrobial [21][22][23], anticoagulant [24], plant growth promoters [25], anticancer agents [26,27], angiotensin I-converting enzyme (ACE) inhibiting activity [28], antidiabetic [29], and antiproliferative [30]. To get all these benefits of the marine phenolics and use them in different delivery systems, such as food, pharmaceuticals, and cosmetics, the compounds need to be extracted from the sample matrix, characterized, and purified.…”

Emerging Technologies for the Extraction of Marine Phenolics: Opportunities and Challenges

Natural phenolic compounds are important classes of plant, microorganism, and algal secondary metabolites. They have well-documented beneficial biological activities. The marine environment is less explored than other environments but have huge potential for the discovery of new unique compounds with potential applications in, e.g., food, cosmetics, and pharmaceutical industries. To survive in a very harsh and challenging environment, marine organisms like several seaweed (macroalgae) species produce and accumulate several secondary metabolites, including marine phenolics in the cells. Traditionally, these compounds were extracted from their sample matrix using organic solvents. This conventional extraction method had several drawbacks such as a long extraction time, low extraction yield, co-extraction of other compounds, and usage of a huge volume of one or more organic solvents, which consequently results in environmental pollution. To mitigate these drawbacks, newly emerging technologies, such as enzyme-assisted extraction (EAE), microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), pressurized liquid extraction (PLE), and supercritical fluid extraction (SFE) have received huge interest from researchers around the world. Therefore, in this review, the most recent and emerging technologies are discussed for the extraction of marine phenolic compounds of interest for their antioxidant and other bioactivity in, e.g., cosmetic and food industry. Moreover, the opportunities and the bottleneck for upscaling of these technologies are also presented.
