Summary: In this study, a systematic sequential extraction process was employed to valorize microalgal biomass for the simultaneous production of high-value products, lutein and phytol, as well as value-added biochemicals like protein, lipid, and carbohydrate. The extraction process involved two steps, resulting in the separation of lutein and phytol with high purity and the extraction of major biochemical compounds. Different strategies were employed to extract protein, lipid, and carbohydrate with optimal recovery rates. The suitability of the extracted biochemicals for aquaculture feed, bioethanol, and biodiesel production was evaluated. This study provides an approach to efficiently develop a biorefinery model for the valorization of microbial biomass.

Summary: Algae biomass is a viable feedstock for manufacturing biofuels due to its various biological elements. The high production costs of algal biofuels hinder their commercialization, thus extraction of high value added bioproducts from algal biomass is required to increase economic viability. This study discusses the economic benefits of a zero-carbon economy and sustainable algae resource in decarbonizing the environment through algal-based biofuel production, and emphasizes the feasibility and commercialization of algae biorefineries.

Summary: The valorization of macroalgae digestate as a secondary resource can lead to the production of high value chemicals through pyrolysis, while the filtered liquid fraction can be used as an alternative culture media for microalgae growth. The digestates showed improved biooil profiles compared to the raw macroalgae. The pyrolyzates from the digestates contained high-value chemicals and the liquid digestate positively influenced microalgae growth.

Summary: This study explores the potential of marine plants, including macroalgae and seagrass, as biorenewable feedstocks for producing 2,5-furandicarboxylic acid (FDCA), a versatile platform chemical. The use of ionic liquid-based solvents (ILS) and deep eutectic solvent (DES) systems, as well as biomodification strategies involving target enzyme-encoding genes, are proposed to enhance FDCA production. The findings pave the way for eco-friendly biorefineries and biorenewable plastics.

Summary: The marine environment provides vast opportunities for aquaculture expansion, but the use of marine organisms as feed materials is not common practice. Underutilized marine organisms such as mussels, Ulva spp., and microbial floc can be cultured and used as aquafeed raw materials, but challenges related to environmental factors and food safety should be addressed.

Summary: Increased incomes, urbanization, and an aging population have led to changes in consumption patterns and increased demand for proteins. Red seaweed, with its high protein content and rich source of essential amino acids, has potential as a protein source. However, the utilization of red macroalgae proteins is still underdeveloped, and further research is needed to evaluate their digestibility and bioavailability.

Summary: This study explores the use of "sea-thermal" treatment of the microalgae Chlorella Vulgaris to produce energy-dense biofuels and value-added liquid products. The processing conditions and reaction medium were found to significantly affect the yields and properties of the products. Low temperatures and short reaction times favored the formation of biocrude, while high temperatures and prolonged processing times promoted the repolymerization of the biocrude to hydrochar. The salinity of the seawater also played a role in these transformations.

Summary: A novel extraction and fractionation concept using Ionic Liquids (ILs) was proposed to extract and recover proteins and carbohydrates from macroalgae. The process involved IL-assisted mechanical shear for initial extraction and two-phase partitioning or ultrafiltration for fractionation. The selective extraction of proteins and the preservation of their native structure were demonstrated. The potential application of this approach in the biorefinery of macroalgae was highlighted.

Summary: Bioconversion of bioresources/wastes using Rhodococcus is a promising approach for producing lipid-derived bioproducts. However, bioconversion involves living cells and is a complex system that requires further understanding. This review highlights the potential of Rhodococcus for producing lipids from various wastes and presents genetic modifications using emerging tools for promoting bioconversion. Additionally, strategies for enhancing the bioaccessibility of lignin and its derived aromatics and synthesizing biodiesel and aviation fuels from lignin and lipids are discussed. The synergistic modification of microbial strains, substrates, and fermentation processes is proposed for sustainable biological lignin valorization.
