To produce high-, medium- and low-molecular-weight hyaluronic acid (HA) at different temperatures using engineered Bacillus subtilis expressing hyaluronidase (HAase) from leech. By overexpressing the HAase gene hya in the HA-producing strain WmB using temperature-sensitive plasmid pKSV7, the engineered strain WmB-PYh produced HA with different molecular weights (8.61 kDa at 32 °C, 0.615 MDa at 42 °C, and 6.19 MDa at 47 °C). In this study, the molecular weight of HA was regulated by using leech HAase expressed from a temperature-sensitive plasmid. We thus obtained different molecular weight HAs by using a single bacterial strain at different culture temperatures.

工程化枯草芽孢杆菌生产的透明质酸的温控分子量

使用工程化枯草芽孢杆菌表达水蛭透明质酸酶 (HAase),在不同温度下生产高、中、低分子量透明质酸 (HA)。通过使用温度敏感质粒 pKSV7 在产 HA 菌株 WmB 中过表达 HAase 基因 hya,工程菌株 WmB-PYh 产生了具有不同分子量的 HA(32 °C 时为 8.61 kDa,42 °C 时为 0.615 MDa 和 6.19 MDa在 47°C)。在这项研究中,HA 的分子量是通过使用从温度敏感质粒表达的水蛭 HAase 来调节的。因此,我们通过在不同培养温度下使用单一细菌菌株获得了不同分子量的 HA。
