“…Novel extraction technologies (Araujo et al, 2013;Esquivel-Hernández et al, 2016) and chemical extraction procedures (Adam, Abert-Vian, Peltier, & Chemat, 2012;Hammed et al, 2013), are both applied to obtain selective extracts of algae rich in desired functional/antimicrobial compounds (Dai & Mumper, 2010).…”

Antimicrobial potential of macro and microalgae against pathogenic and spoilage microorganisms in food

et al. 2017

Algae are a valuable and never-failing source of bioactive compounds. The increasing efforts to use ingredients that are as natural as possible in the formulation of innovative products has given rise to the introduction of macro and microalgae in food industry. To date, scarce information has been published about algae ingredients as antimicrobials in food. The antimicrobial potential of algae is highly dependent on: (i) type, brown algae being the most effective against foodborne bacteria; (ii) the solvent used in the extraction of bioactive compounds, ethanolic and methanolic extracts being highly effective against Gram-positive and Gram-negative bacteria; and (iii) the concentration of the extract. The present paper reviews the main antimicrobial potential of algal species and their bioactive compounds in reference and real food matrices. The validation of the algae antimicrobial potential in real food matrices is still a research niche, being meat and bakery products the most studied substrates.

“…Degradation of cell walls by an enzymatic pathway has also been used in microalgal treatment (e.g. in Chlorella vulgaris), but it is still too expensive to be applied widely in industry (Hammed et al, 2013).…”

“…In this case, microalgae subjected to HPS at 210 °C had the highest glucose yield (1.37 g glucose/g TTS, or 0.28 g glucose/g biomass before pre‐treatment), followed by the HPS‐microalgae 104 °C treatment, meaning that the solubilization of components due to HPS has a positive effect on glucose production. In subcritical water the cellulose is rapidly solubilized, and also the smaller the substrate size, the higher the enzyme degradation, explaining the higher yields for pre‐treated microalgae. Before HPS, the substrate size corresponds to the microalgae cell size (2–10 µm), but during HPS there is formation of microalgae clusters that can reach up to 3 mm in size.…”

Cellulose from microalgae offers potential value as a source of fermentable sugars. This cellulose can be used after the extraction of other valued products in the biomass such as bio‐crude. In this paper, an integrated approach to bio‐crude and glucose recovery from microalgae was studied. First the bio‐crude recovery efficiency using high‐pressure steaming was calculated for microalgae cultures with different lipid and cellulose contents. Next, enzymatic hydrolysis was applied to obtain fermentable sugars. The best extraction efficiency with high‐pressure steaming was 97.9 ± 8.3 % for the algae containing the lowest cellulose content. The algae treatment with high‐pressure steaming at 210 °C followed by hydrolysis with cellulase led to glucose yields of 0.28 g/gbiomass, indicating that high‐pressure steaming is a suitable method for the production of two sources of bio‐fuels (bio‐crude and glucose) from microalgae.

“…Polysaccharides, such as alginate, can form a gel to resist the influx of water into the cell structure. Some cell polymer may even bind to biocompounds and decrease their solubility 27 , which would explain the observed variation in yield as well as chemical compositions of the watersoluble extracts obtained from the seaweed species. The inhibition of NO synthesis in LPS-induced RAW 264.7 macrophage cell lines by all extracts obtained from brown seaweed is in agreement with our results.…”
