title: Growth of Cryptococcus neoformans in a thiamine-free medium.
abstract: The growth of Cryptococcus neoformans in a minimal liquid synthetic medium with or without thiamine (10 micrograms/ml) was investigated. In these media the presence or absence of thiamine had no effect on the development of C. neoformans. To check these results, we performed a series of experiments on a solid form of the minimal synthetic medium. In this study a series of six serial transfers were carried out to starve the cells of nutrients that may have been carried over from their growth on rich media. In each of the transfers on the solid synthetic medium, C. neoformans showed a similar and scarce growth. This finding indicates that C. neoformans could be autotrophic in respect to thiamine.
