Abstract

To increase the limited commercial utility and lessen the negative environmental effects of the massive growth of brown macroalgae, this work illustrates the feasibility of valorizing the invasively proliferated Sargassum latifolium into different value-added products. The proximate analysis recommends its applicability as a solid biofuel with a sufficient calorific value (14.82 ± 0.5 MJ/kg). It contains 6.00 ± 0.07% N + P2O5 + K2O and 29.61 ± 0.05% organic C. Its nutritional analysis proved notable carbohydrate, ash, protein, and fiber contents with a rational amount of lipid and a considerable amount of beneficial macronutrients and micronutrients, with a low concentration of undesirable heavy metals. That recommends its application in the organic fertilizer, food, medicine, and animal fodder industries. A proposed eco-friendly sequential integrated process valorized its biomass into 77.6 ± 0.5 mg/g chlorophyll, 180 ± 0.5 mg/g carotenoids, 5.86 ± 0.5 mg/g fucoxanthin, 0.93 ± 0.5 mg/g β-carotene, 21.97 ± 0.5% (w/w) alginate, and 16.40 ± 0.5% (w/w) cellulose, with different industrial and bioprocess applications. Furthermore, Aspergillus galapagensis SBWF1, Mucor hiemalis SBWF2, and Penicillium oxalicum SBWF3 (GenBank accession numbers OR636487, OR636488, and OR636489) have been isolated from its fresh biomass. Those showed wide versatility for hydrolyzing and saccharifying its polysaccharides. A Gram-negative Stutzerimonas stutzeri SBB1(GenBank accession number OR764547) has also been isolated with good capabilities to ferment the produced pentoses, hexoses, and mannitol from the fungal saccharification, yielding 0.25 ± 0.014, 0.26 ± 0.018, and 0.37 ± 0.020 g ethanol/g algal biomass, respectively. Furthermore, in a pioneering step for valuing the suggested sequential biomass hydrolysis and bioethanol fermentation processes, the spent waste S. latifolium disposed of from the saccharification process has been valorized into C-dots with potent biocidal activity against pathogenic microorganisms.

马尾藻生物燃料和可持续增值产品价值潜力研究。
为了提高马尾藻有限的商业用途,减少褐色大型藻类大量生长对环境造成的负面影响,本研究阐述了将入侵增殖的马尾藻转化为不同增值产品的可行性。近似物分析表明,马尾藻具有足够的热值(14.82 ± 0.5 兆焦/千克),可用作固体生物燃料。其营养分析表明,其碳水化合物、灰分、蛋白质和纤维含量显著,脂质含量合理,含有大量有益的宏量营养素和微量营养素,不良重金属含量较低。建议将其应用于有机肥料、食品、医药和动物饲料行业。一种拟议的生态友好型连续综合工艺将其生物质转化为 77.6 ± 0.5 mg/g 叶绿素、180 ± 0.5 mg/g 类胡萝卜素、5.86 ± 0.5 mg/g 狐黄素、0.93 ± 0.5 mg/g β-胡萝卜素、21.97 ± 0.5%(重量比)海藻酸和 16.40 ± 0.5%(重量比)纤维素,可用于不同的工业和生物工艺。此外,还从其新鲜生物质中分离出 Aspergillus galapagensis SBWF1、Mucor hiemalis SBWF2 和 Penicillium oxalicum SBWF3(GenBank 编号 OR636487、OR636488 和 OR636489)。这些菌株在水解和糖化其多糖方面表现出广泛的多功能性。此外,还分离出一种革兰氏阴性的 Stutzerimonas stutzeri SBB1(GenBank 编号 OR764547),它对真菌糖化产生的戊糖、己糖和甘露醇具有良好的发酵能力,每克藻类生物质可分别产生 0.25 ± 0.014、0.26 ± 0.018 和 0.37 ± 0.020 克乙醇。此外,在对所建议的生物质水解和生物乙醇发酵连续过程进行估价方面迈出了开创性的一步,将糖化过程中产生的废弃 S. latifolium 转化为对病原微生物具有强大生物杀灭活性的 C-dots。
