The development of alternative proteins derived from fungi-based sources is gaining recognition due to their health benefits and lower environmental impact, compared to traditional animal-based sources. In this study, we investigated the culture conditions for mycelia, focusing on the nutritional requirements and yield optimization using solid surface culture and liquid-state culture methods. Our findings indicate that optimal culture conditions involve glucose as the primary carbon source, with an initial pH of 6.0. By the eighth day of the culture period, media formulated with amaranth seed flour and Bambara groundnut flour yielded the highest mycelial protein content, characterized by a compact filamentous network with fewer open pores. Additionally, urea supplementation at 0.01% concentration on amaranth seed-based nutrient medium significantly increased the protein content from 31.4% to 38.7% (dry weight basis). The research findings contribute to the development of fungal-based proteins, which are essential in the production of sustainable food products.
与传统的动物源蛋白质相比,基于真菌来源的替代蛋白质因其对健康有益且对环境影响较小而日益受到认可。在本研究中,我们研究了菌丝体的培养条件,重点关注使用固体表面培养和液态培养方法时的营养需求和产量优化。我们的研究结果表明,最佳培养条件是以葡萄糖作为主要碳源,初始pH值为6.0。在培养期的第八天,用苋菜籽粉和 Bambara 花生粉配制的培养基产生了最高的菌丝体蛋白质含量,其特征是具有紧密的丝状网络且开孔较少。此外,在以苋菜籽为基础的营养培养基中添加0.01%浓度的尿素,可使蛋白质含量从31.4%显著提高到38.7%(以干重计)。这些研究结果有助于基于真菌的蛋白质的开发,这对于可持续食品的生产至关重要。
