红/蓝光对粘红酵母生长及产物产量的影响

Effect of blue/red light on growth and properties of red yeast

为深入了解光信号对酵母菌生长发育的影响,研究红光和蓝光对粘红酵母菌生长及产物产量的影响。结果表明,红光培养促使粘红酵母生物量显著增加,还可提高粘红酵母中蛋白质和核酸的含量,提高粘红酵母类胡萝卜素和麦角固醇含量,因此可考虑在粘红酵母工业化生产类胡萝卜素和麦角固醇时引入红光这一参数。蓝光在提高粘红酵母生物量方面不明显,但可增加粘红酵母细胞质膜的通透性,并提高粘红酵母油脂和麦角固醇含量。光质在粘红酵母生长过程中的确有重要作用,其作用机制和原理尚需进一步深入研究与探讨。

In order to understand the effect of the light signal on the growth and development of yeast,the effects of red and blue light on the growth and yield of the growth of the yeast were studied.Results showed that the red culture could prompt the Rhodotorula glutinis biomass increased significantly,improve the content of protein and nucleic acid in Rhodotorula glutinis,improve Rhodotorula glutinis kind of carotene and ergosterol content.The red light can be considered to introduced into Rhodotorula glutinis industrialized production of carotene and ergot solid alcohol. The Blue ray in improving the Rhodotorula glutinis biomass was not obviously,but can be increased Rhodotorula glutinis cell membrane permeability,and improve the Rhodotorula glutinis grease and ergosterol content.Light quality in Rhodotorula glutinis growth process does have an important role,its mechanism and principle still need further in-depth study and discussion.
