Special Issue Information

Dear Colleagues,

This Special Issue will focus on the latest research in the development of technologies used to investigate various aspects of the impact of the production of fermented bioactive products from marine biomass. Bioactive metabolites produced by microorganisms exhibit various biological activities, such as antimicrobial, antifungal, anti-inflammatory, and anticancer activities. Recently, fermented products have been considered a promising alternative to meet the increasing consumer demand for healthy food.

This Special Issue includes not just innovative and varied approaches to boost the efficiency of emerging fermentation products but also features articles detailing recent findings and uses in characterizing newfound compounds. Our aim is to create a platform where experts worldwide can exchange research and perspectives on different facets of the bioactive metabolites attainable through fermentation, fostering more discussions and enhancing our understanding of the subject.

We welcome research articles, review articles, and short communications.

Dr. In Yung Sunwoo
Guest Editor

Abstract
This study explores the potential of producing bioethanol from seaweed biomass and reusing the residues as antioxidant compounds. Various types of seaweed, including red (Gelidium amansii, Gloiopeltis furcata, Pyropia tenera), brown (Saccharina japonica, Undaria pinnatifida, Ascophyllum [...] Read more.
This study explores the potential of producing bioethanol from seaweed biomass and reusing the residues as antioxidant compounds. Various types of seaweed, including red (Gelidium amansii, Gloiopeltis furcata, Pyropia tenera), brown (Saccharina japonica, Undaria pinnatifida, Ascophyllum nodosum), and green species (Ulva intestinalis, Ulva prolifera, Codium fragile), were pretreated with dilute acid and enzymes and subsequently processed to produce bioethanol with Saccharomyces cerevisiae BY4741. Ethanol production followed the utilization of sugars, resulting in the highest yields from red algae > brown algae > green algae due to their high carbohydrate content. The residual biomass was extracted with water, ethanol, or methanol to evaluate its antioxidant activity. Among the nine seaweeds, the A. nodosum bioethanol residue extract (BRE) showed the highest antioxidant activity regarding the 2,2-diphenyl-1-picrylhydrazyl (DPPH) activity, ferric reducing antioxidant power (FRAP), and reactive oxygen species (ROS) inhibition of H2O2-treated RAW 264.7 cells. These by-products can be valorized, contributing to a more sustainable and economically viable biorefinery process. This dual approach not only enhances the utilization of marine resources but also supports the development of high-value bioproducts. Full article
