“…A number of studies have investigated alternative processing routes to efficiently convert different species of macroalgae into advances biofuels as bioethanol, which typically follow conventional methods of biomass hydrolysis previously developed for use with lignocellulosic feedstocks (Jung et al, 2013;Ruiz et al, 2015; Siller-Sánchez et al;…”

“…The most used algae in industry is the macroalga called Japanese wakame ( Undaria pinnatifida ), which has a high concentration of pigments, being greater than 9.6% of its composition 21 . Other algal sources have been Saccharina , Turbinaria , Laminaria , Fucus and Macrocystis 48,49 . Figure 3 shows the main most abundant pigments in brown algae.…”

Fucoxanthin is a high‐added‐value carotenoid compound. It has been extracted from marine sources by various extraction methods in different countries. Fucoxanthin finds application in areas such as the pharmaceutical, cosmetic and food industries. However, recent research has shown that fucoxanthin has anticancer, antioxidant, anti‐obesity, antidiabetic, hypoglycemic and neuroprotective activities, which suggest its use as a food supplement. Finally, this review aims to show the latest advances of fucoxanthin from seaweeds in the extraction process, chemical characterization and bioactivities in the development of third‐generation biorefineries and circular bioeconomy. © 2021 Society of Chemical Industry (SCI).

“…In addition, the high moisture content of macroalgae makes HTT a promising processing technology for the direct use of macroalgae in the production of biofuels and compounds with high added value. In the case of brown algae, which contain sulfated polysaccharides, the hydrolysis caused by the application of HTT generates a drop in pH, contributing to an effective self-catalyzed process 31 .…”

Study of microwave hydrothermal production of lactic acid from seaweed-derived alginate using a response surface methodology based on the Box-Behnken design

A microwave hydrothermal treatment was used for the chemical production of lactic acid from alginate extracted from the brown seaweed Padina Durvillaei, collected in the coastal area of Ecuador. The microwave hydrothermal treatment was studied through a response surface methodology based on the Box-Behnken design, using temperature, reaction time, and catalyst concentration as the manipulated variables and the yield as a response factor. The characterization of alginate was performed by Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). The lactic acid produced was quantified using Gas Chromatography - Ion Mobility Spectrometry (GC-IMS). The results show that temperature and catalyst concentration played the most critical roles in alginate extraction and lactic acid production. The optimal experimental conditions for alginate extraction from brown seaweed were: temperature = 92.91°C, time = 110.81 min and catalyst (Na2CO3) concentration = 2.60%, with a yield = 29.19%. Although the experimental evidence indicates a positive influence of microwaves' use on the production of lactic acid from alginate through hydrothermal treatment, a new study considering temperatures above 220°C and reaction times below 60 min should be developed.
