This work reports a novel solution-based method to trigger the growth of diatoms for enhanced biomass production, which can efficiently stimulate their applications in nutraceuticals, aquaculture and wastewater remediation. The optimization for the growth of three marine diatoms species was performed using inductively coupled plasma (ICP) synthesized nanosilica which can be a cost-effective and productive method for biomass production. The exponential growth phase was achieved in 14 days with high biomass productivity compared to F/2-Si Media [Chaetoceros sp. (125 ± 3 & 750 ± 3 mgLday); Skeletonema sp., (185.3 ± 2.63 & 562.5 ± 3.96 mgLday) and Thalassiosira sp. (312.5 ± 2.51 & 433.5 ± 1.80 mgLday)] along with a sharp rise of 50-100 fold increment in pigmentation. This work opens up an avenue with novel insights to trigger the growth of diatoms on large scale leading to their better exploitation towards biotechnological applications.
本工作报道了一种新颖的基于溶液的方法来触发硅藻的生长以提高生物量产量，这可以有效地促进它们在营养保健品、水产养殖和废水修复中的应用。使用电感耦合等离子体（ICP）合成的纳米二氧化硅对三种海洋硅藻物种的生长进行了优化，这是一种具有成本效益和生产力的生物量生产方法。与 F/2-Si 培养基相比，在 14 天内达到了指数生长阶段，具有较高的生物量生产力[Chaetoceros sp.（125±3 和 750±3 mgLday）；Skeletonema sp.，（185.3±2.63 和 562.5±3.96 mgLday）和 Thalassiosira sp.（312.5±2.51 和 433.5±1.80 mgLday）]，同时色素含量急剧增加了 50-100 倍。这项工作为大规模触发硅藻生长开辟了一条新途径，从而更好地开发它们在生物技术应用方面的潜力。
