“…Due to the high content of carbon and low content of lignin, macroalga have been considered a viable biomass for biofuels production and are included in the third generation bioethanol resources [ 35 , 36 ]. However, as several fractions of macroalgae have high added value, bioethanol production is usually considered as a part of a biorefinery process where high added value fractions are recovered for other applications and only the residual low value fraction, usually rich in cellulose, is used as substrate, after hydrolysis, in the fermentative bioethanol production process.…”

Seaweeds are a renewable natural source of valuable macro and micronutrients that have attracted the attention of the scientists in the last years. Their medicinal properties were already recognized in the ancient traditional Chinese medicine, but only recently there has been a considerable increase in the study of these organisms in attempts to demonstrate their health benefits. The extraction process and conditions to be used for the obtention of value-added compounds from seaweeds depends mainly on the desired final product. Thermochemical conversion of seaweeds, using high temperatures and solvents (including water), to obtain high-value products with more potential applications continues to be an industrial practice, frequently with adverse impact on the environment and products’ functionality. However more recently, alternative methods and approaches have been suggested, searching not only to improve the process performance, but also to be less harmful for the environment. A biorefinery approach display a valuable idea of solving economic and environmental drawbacks, enabling less residues production close to the much recommended zero waste system. The aim of this work is to report about the new developed methods of seaweeds extractions and the potential application of the components extracted.

However, the utilization of edible crops for biofuel production has received wide spread criticism due to food versus fuel issue 79) . Besides that, the production of starch and sugar raw material is still inadequate to meet the demand for bioethanol production.…”

“…According to a report, in the United States, the total ethanol production in 2018 reached 61 billion liters 2 . Among various ethanol production processes, fermentation has grown rapidly in recent years due to its low cost, environmental friendliness and safety 3‐5 . However, due to the inhibitory effects of ethanol on yeast and enzymes, the ethanol concentration in the fermentation reaction is always a trade‐off with the product conversion rate 6‐8 .…”

Screen‐printing of nanocube‐based flexible microchips for the precise biosensing of ethanol during fermentation

The real‐time and full concentration analysis of ethanol during the fermentation reaction allows the precise control of the microbial metabolism to promote the conversion rate; however, only few techniques can directly detect the fermentation broth without pretreatment. To address this issue, a screen‐printed biosensing microchip (SPBM) was proposed to analyze the ethanol concentration in fermentation, relying on designing a well‐defined nanocubic structure of an Au nanoparticles/nickel hexacyanoferrate nanocomposite. This nanocomposite was then made into a printing ink for the direct fabrication of a SPBM. The as‐prepared microchip exhibits an ultrahigh electrocatalysis on nicotinamide adenine dinucleotide with a high sensitivity of 96.2 ± 2.9 μA·mM−1·cm−2. Moreover, after the immobilization of alcohol dehydrogenase, the accurate and rapid monitoring of the ethanol concentration during the real fermentation reaction can be realized within an ultrawide linear range of 0.1–10 M in the broth without any pretreatment.
