“…Seaweed cultivation is economically viable due to the presence of high-value compounds in algae cells, which are extracted and used for the manufacture of cosmetics, pharmaceuticals, and chemical compounds. El-baz et al [17] showed that among species of red and green algae, U. lactuca had a higher lipid concentration and inhibitory actions on viral and bacterial activities. In industry, macroalgae have wide applicability, with them being a good nutritional alternative and having a good acceptability, as shown by Turan and Tekogul [18].…”

A biofloc system is rich in nutrients, which favors the cultivation of macroalgae, but the influence of the system on the performance of macroalgae is unknown. The objective of this study was to analyze the feasibility of introducing the macroalgae Ulva lactuca into the culture of Litopenaeus vannamei in a biofloc system. The first experiment evaluated the influence of 400 mg L−1 and 30 mg L−1 solids concentration of the system in biofloc and von Stosch culture medium on macroalgae growth. In the second experiment, the densities of 1, 2, and 3 g L−1 of U. lactuca were cultivated in an integrated system with shrimp and monoculture treatment. Both experiments had 35 days of cultivation. There was no significant difference in macroalgae growth between the treatments with biofloc and von Stosch culture medium. In the integrated culture, the density of 1 g L−1 showed better nutrient absorption. Shrimp performance was not affected by macroalgae cultivation. In conclusion, the solids did not affect the growth of the macroalgae, and it could be cultivated in a biofloc system for nitrate uptake in integrated culture with shrimp.

The marine ecosystem is a rich source of novel secondary metabolites with significant biomedical applications. Seaweeds are considered as the treasury of secondary metabolites with various biological activities. This study aims to analyze antioxidant and antimicrobial potential in green seaweed Ulva fasciata and brown seaweed Dictyota dichotoma. Extracts from four different solvents such as petroleum ether, chloroform, ethyl acetate and methanol using Soxhlet apparatus were tested for the qualitative analysis of phytochemicals. Secondary metabolites were analyzed quantitatively to correlate with the antioxidant (DPPH assay) and antimicrobial potential of seaweeds. Results showed a better antioxidant activity of U. fasciata in its methanolic extract (89.29%) and D. dichotoma manifested a maximum antioxidant activity (70.1%) for its ethyl acetate extract. Structural characteristics of seaweed derived bioactive material were investigated by Fourier transform infrared spectroscopy (FTIR) and manifested the presence of alcohol and phenolic compounds. The inhibition zone formed around the crude extract reveals the antimicrobial nature of bioactive substances of seaweed extract against the pathogens. High inhibition and antioxidant activity indicate an effective drug’s evolution from seaweeds against human pathogens.
