The yeast Phaffia rhodozyma, a promising microbial producer of the carotenoid astaxanthin, was cultivated in batch and continuous processes in an agitated and aerated fermenter using an acid peat extract based culture medium. For the accelerated growth phase, the mean specific growth rate and doubling time were found to be 0.038 h-1, and 18.24 hours, respectively. The production of astaxanthin was found to be basically growth associated, the maximum concentrations of the pigment produced in batch culture and continuous cultivation being similar.
红发夫酵母是一种很有前景的类胡萝卜素虾青素微生物生产者，在搅拌通气的发酵罐中，使用基于酸性泥炭提取物的培养基进行分批和连续培养。在加速生长阶段，平均比生长速率和倍增时间分别为0.038 h-1和18.24小时。发现虾青素的产生基本与生长相关，分批培养和连续培养中产生的色素最大浓度相似。
