This suggests that its dietary consumption could help mitigate metabolic diseases induced by high-fat diet (HFD). To test this hypothesis, we initially analyzed the nutritional components of the macroalga, and evaluated its acute oral toxicity and long-term safety. Subsequently, we explored the impacts of its dietary intake on HFD-fed mice. Additionally, 16S rRNA sequencing was employed to further elucidate the mechanism underlying the protective effects of this macroalga against HFD-induced metabolic abnormalities. Our results revealled that <em>S. fusiforme</em> has a desirable nutrient profile, characterized by rich carbohydrates, polyunsaturated fatty acids, and carotenoids, and is also highly safe for consumption. Its dietary intake remarkably alleviated HFD-induced metabolic disorders. Analysis of gut microbiota showed that HFD consumption increased the relative abundance of Firmicutes and decreased Bacteroidetes. This trend was further exacerbated by <em>S. fusiforme</em> supplementation, resulting in a higher Firmicutes/Bacteroidetes ratio compared to both the control and HFD groups. At the genus level, <em>Muribaculum</em>, <em>Lactobacillus</em>, <em>Clostridia_UCG_014</em>, <em>Clostridium</em>_sp, <em>Acetatifactor</em>, <em>Eubacterium_coprostanoligenes</em>, and <em>IS_44</em> (from family Nitrosomonadaceae) were significantly enriched in the mice supplemented with <em>S. fusiforme</em>.

Although the effects of plant growth regulators (PGRs) on enhancing microalgal growth and lipid content have been widely demonstrated, the synergistic effects of their combinations on improving lipid productivity in <em>Tribonema</em> sp. remain unclear. In this study, we investigated the comparative effects of five PGRs (e.g., fulvic acid, melatonin, gibberellin, γ-aminobutyric acid [GABA], and indoleacetic-3-acid [IAA]) at different concentrations (0.1–10 mg/L) on the growth, nitrogen uptake, and lipid content of <em>Tribonema</em> sp. The results showed that 10 mg/L GABA and 0.1 mg/L IAA were optimal conditions, contributing to an approximately 33.00 % increase in lipid productivity compared with the control (without PGRs). Based on these findings, the combination of optimized concentrations of GABA and IAA, especially in equal proportions, resulted in a more desirable fatty acid profile and produced the highest biomass, lipid content, and lipid productivity, with increases of 23.55 %, 25.62 %, and 54.95 %, respectively, over the control. This combination also significantly increased nitrogen removal efficiency in the medium, which was 46.24 % higher that of the control. These results were attributed to the significant upregulation of genes associated with nitrogen metabolism mediated by the synergy of IAA and GABA, promoting nitrate uptake by algal cells in the medium. Genes involved in photosynthesis and lipid synthesis were also upregulated, facilitating simultaneous biomass and lipid accumulation to maximize lipid productivity. Overall, this study is the first to report the combined application of GABA and IAA as an effective strategy to enhance lipid productivity in <em>Tribonema</em> sp., providing insights into the underlying mechanisms.

This study aimed to assess the efficacy of C-PC and intracellular extraction from <em>Ocillatoria okeni</em> TISTR8549 utilizing freezing-thaw (FT), pulsed electric field (PEF), and high-pressure homogenization (HPH) techniques. Additionally, the potential of <em>O. okeni</em> extract as a supplement and substitute for fetal bovine serum (FBS) in HaCaT cell culture was investigated. FT appeared to be the most proper method for C-PC extraction, yielding the highest purity and yield, although requiring 18 cycles for product accomplishment. PEF seemed unsuitable for intracellular component extraction from cyanobacteria with thick cell walls. The need for increased pulses resulted in thermal elevation and prolonged incubation times led to protein degradation. HPH proves to be an effective method for intracellular extraction, yielding high protein content suitable for the potential substitution of FBS in mammalian cell culture. Particularly, increasing pressure during HPH extraction leads to a decrease in protein yield. Resazurin and SRB assays revealed that adding algal extract in culture medium at concentrations of 1 % (<em>w</em>/<em>v</em>) improved HaCaT cell viability without disrupting cell morphology and metabolic processes. However, substituting algal extract in FBS resulted in cell proliferation decrease. Therefore, supplementing <em>O. okeni</em> extract during cell culture improved HaCaT cell proliferation, but it was unsuitable substitute for FBS in the culture medium.
