一株红酵母产类胡萝卜素研究

A Study on Carotenoid Produced by a Rhodotorula

介绍一种分离自土壤的红酵母菌株，通过实验确定了该菌株的最适生长温度（２８℃）和最适ｐＨ值（６．０）及产类胡萝卜素的最适培养时间（７２ｈ）。在不同的培养条件下，分析了菌体生物量的形成和类胡萝卜素的产量之间的关系。

This article reports a species of Rhodotorula rubra. From the soil, through many experiments we define the best temperature(28℃),pH(6.0) for growth the Rhodotorula and the best time (72 h) for producing Carotenoid. Under the different conditinos we analyse the relations between the output of Carotenoid and the biomass of the Rhodotorula. Finally,define the best culture medium of this Rhodotorula rubra.
