摘要

为了提高产品的产量和质量,降低生产成本,发酵技术在各个方面仍在不断发展。通过优化影响发酵过程的因素,包括微生物本身和环境,可以提高发酵产物的产量。例如,原料的醋酸生产过程可以与使用厌氧和兼性厌氧酿酒葡萄球菌和专性好氧乙酰葡萄球菌混合培养的浸没分批发酵同时进行。这个系统非常简单,因为它只有一个阶段。在该系统中,可以通过评估培养基中营养物质的有效性,确定微生物丰度和搅拌速度的最佳比例来提高乙酸的产率。在最佳条件下,乙酸产率提高,转化效率高。通过将这些发现与操作系统中的先进技术相结合,这些结果可以应用于工业规模。

Streamlining the Fermentation Process Using Mixed Cultures
Fermentation technology is still being developed in all aspects, with the aim of improving the yields and qualities of products and reducing the costs of production. Increasing the yields of fermentation products can be accomplished by optimizing the factors that influence the process, including both the microbe itself and the environment. For example, the acetic acid production process from raw materials can be performed simultaneously with submerged batch fermentation using mixed cultures of anaerobic and facultative anaerobic S. cerevisiae and obligate aerobic A. aceti . This system is very simple because it only has one stage. In this system, efforts can be made to enhance the yields of acetic acid production, including evalu-ating the availability of nutrients in the medium and determining the optimum proportion of microbial abundance and agitation speed. Under optimal conditions, the resulting increases in acetic acid yields occur with high conversion efficiency. These results can then be applied on an industrial scale by integrating these findings with advanced technologies in the operating system.
