Integrated multitrophic aquaculture (IMTA) is a model that integrates organisms from different trophic levels, all sharing the same production system and, consequently, the nutrients. This study adopted shrimp (Penaeus vannamei) as the main species, tilapia (Oreochromis niloticus) as an organic consumer, and the seaweed (Ulva ohnoi) at different densities as an inorganic consumer in a biofloc production system. The study consisted of an experiment with three treatments and four replicates each: 1) No seaweed; 2) Seaweed 1 g L-1 (density of 1 g L-1 of U. ohnoi), and 3) Seaweed 2 g L-1 (density of 2 g L-1 of U. ohnoi). Shrimp (3.82 ± 0.05 g) were stocked in 800 L tanks at a density of 275 shrimp m-3 , fish (14.44 ± 0.57 g) in 90 L tanks at a density of 267 tilapia m-3 , and 50 and 100 g of seaweed stocked in 50 L tanks, corresponding to treatments with 1 and 2 g L-1 , respectively. The integration of U. ohnoi at densities of 1 g L-1 and 2 g L-1 with P. vannamei and O. niloticus benefited the system through higher nitrogen (13,22 and 13,10% higher in the treatments 1 g L-1 and 2 g L-1 respectively) and phosphorus recovery (25,57 and 34% respectively) and an increase in total productivity (15,32 and 19,22% respectively), generating an ecological gain. Considering the similar final biomass of seaweed in a multitrophic system with shrimp and tilapia, the use of U. ohnoi at a density of 2 g L-1 is recommended since nutrient recovery by fish and shrimp was higher at this density. |

Improving key biomass functionalities necessitates effective liquid-liquid fractionation methods for heavy bio-oil. Here, fast-pyrolysis bio-oil derived from eucalypt wood was fractionated in cold water to separate insoluble and water-soluble fractions. We focus on the water-soluble fraction, a promising renewable source of chemicals with potential antioxidant and antimicrobial approaches. Fast-pyrolysis bio-oil was fractionated in three oil-to-water ratios, 1:100, 1:50, and 1:35, separating the pyrolytic lignin and producing water-soluble fractions as byproducts. The water-soluble fractions were analytically investigated through physicochemical properties, chemical composition by chromatography, phenolic content, antioxidant activity, antimicrobial activity, and their storage stability. Higher water content in the pyrolytic lignin separation resulted in higher yield and higher molecular weight compounds concentration in the water-soluble fractions, with the presence of highvalue- added chemicals, such as catechol, vanillin, and levoglucosan. Levoglucosan was the dominant chemical identified in the water-soluble fractions, notably for the 1:50 oil-to-water ratio. These remarkable chemicals and a high phenolic content contribute to both high antioxidant and antimicrobial activities. Despite the low concentration, all water-soluble fractions exhibited intense inhibition of Trametes versicolor and Gloeophyllum trabeum fungi. The fraction 1:50 completely inhibited the fungal activity. Both 1:100 and 1:50 fractions showed antibacterial activity for Escherichia coli and Staphylococcus aureus. Regardless of the oil-to-water ratio, water-soluble fractions exhibited a relative storage chemical stability under accelerated aging conditions for 43 days. Therefore, water-soluble fractions of fast-pyrolysis bio-oil derived from a simple method to separate pyrolytic lignin are functional materials with remarkable antioxidant and antimicrobial properties and, hence, upgrading bio-oil based on their functionalities.
