摘要
稻草是酵母油(YO)生产和生物聚氨酯(BPU)泡沫形成的替代原料。本研究利用水稻秸秆水解物(RSH)作为主要碳源,优化了酵母生长和副酵母(Pseudozyma parantarctica)的 YO 产量。研究探索了喂料批处理策略,以提高 YO 的生产效率并将其转化为 BPU 泡沫。事实证明,优化条件对从 RSH-OPM 中产生生物质和 YO 非常有效。喂料-分批法大大提高了生物量、YO 产量和含油量,分别达到 7.35 ± 0.18 g/L、3.77 ± 0.09 g/L 和 51.21 ± 0.15 %(w/w)。YO的主要脂肪酸(FA)组成为C:16至C:18脂肪酸,占92%以上。基于 RSH 的 YO 成功转化为硬质和半硬质 BPU 泡沫。这项研究证明了使用 RSH 作为低成本和可再生碳源生产 YO 和形成 BPU 泡沫的可行性和潜力。
Sustainable production of yeast oil from rice straw hydrolysate by Pseudozyma parantarctica through fed-batch cultivation for bio-polyurethane foam formation
Rice straw serves as an alternative feedstock for yeast oil (YO) production and bio-polyurethane (BPU) foam formation. This study optimized yeast growth and YO production by Pseudozyma parantarctica, utilizing rice straw hydrolysate (RSH) as the primary carbon source. Fed-batch strategies were explored to enhance YO production efficiency and its conversion into BPU foam. The optimized conditions proved highly effective in yielding biomass and YO from RSH-OPM. The fed-batch approach significantly improved biomass, YO production, and oil content to 7.35 ± 0.18 g/L, 3.77 ± 0.09 g/L, and 51.21 ± 0.15 % (w/w), respectively. The main fatty acid (FA) compositions of YO consisted of C:16 to C:18 FAs for over 92 %. RSH-based YO was successfully transformed into both rigid and semi-rigid BPU foams. This research demonstrated the feasibility and potential of using RSH as a low-cost and renewable carbon source for YO production and BPU foam formation.
