“…To do so, the proliferation of biorefineries is needed due to their potential for converting waste biomass into value-added products and their capability to reduce waste, increase resource efficiency, and create new revenue streams [3]. Even though biorefineries still face some problems that are being studied to be solved [4,5], there are many technological advances that allow the development of biofuels or value-added products based on a large variety of sources such as microalgal [6,7] and seaweed [8], lignin [9], rice straw waste [10] or food waste [11], among others.…”

(1) Background: Bioeconomy aims to reduce dependence on non-renewable resources and foster economic growth through the development of new bio-based products and services. Achieving this goal requires social acceptance and stakeholder engagement in the development of sustainable technologies. The objective of this data article is to provide a dataset derived from a survey with a representative sample of 500 citizens over 18 years old based in the Community of Madrid. (2) Methods: We created a questionnaire on the social acceptance of technologies and bio-based products to later gather the responses using a SurveyMonkey panel for the Community of Madrid through an online CAWI survey; (3) Results: A dataset with a total of 82 columns with all responses is the result of this study. (4) Conclusions: This data article provides not only a valuable representative dataset of citizens of the Community of Madrid but also sufficient resources to replicate the same study in other regions.

“…In the present study, we demonstrated the feasibility of fermenting the biomass of green alga Enteromorpha to produce fatty acids. More importantly, fermentation of macroalgae waste can improve the release of bioactive compounds, but the target compound and algae characteristics determine the fermentation type and conditions [29]. Applying pretreatment can promote a higher release of bioactive compounds, but excessive treatment can lead to degradation and loss of bioactive properties [57].…”

“…While all macroalgae have cellulose, the specific types of carbohydrates present vary among the different groups. Brown algae, for instance, mainly contain laminarin, mannitol, alginate, glucan, and fucoidan, while red algae have carrageenan, agar, and lignin, and green algae possess mannan, ulvan, and starch [29]. To achieve environmental benefits and improve product quality while eliminating any residual waste, the most desirable approach for utilizing marine macroalgae waste appears to be the cascade biorefinery approach [30].…”

Thraustochytrids are unicellular marine heterotrophic protists, which have recently shown a promising ability to produce omega-3 fatty acids from lignocellulosic hydrolysates and wastewaters. Here we studied the biorefinery potential of the dilute acid-pretreated marine macroalgae (Enteromorpha) in comparison with glucose via fermentation using a previously isolated thraustochytrid strain (Aurantiochytrium limacinum PKU#Mn4). The total reducing sugars in the Enteromorpha hydrolysate accounted for 43.93% of the dry cell weight (DCW). The strain was capable of producing the highest DCW (4.32 ± 0.09 g/L) and total fatty acids (TFA) content (0.65 ± 0.03 g/L) in the medium containing 100 g/L of hydrolysate. The maximum TFA yields of 0.164 ± 0.160 g/g DCW and 0.196 ± 0.010 g/g DCW were achieved at 80 g/L of hydrolysate and 40 g/L of glucose in the fermentation medium, respectively. Compositional analysis of TFA revealed the production of equivalent fractions (% TFA) of saturated and polyunsaturated fatty acids in hydrolysate or glucose medium. Furthermore, the strain yielded a much higher fraction (2.61–3.22%) of eicosapentaenoic acid (C20:5n-3) in the hydrolysate medium than that (0.25–0.49%) in the glucose medium. Overall, our findings suggest that Enteromorpha hydrolysate can be a potential natural substrate in the fermentative production of high-value fatty acids by thraustochytrids.
