Exogenous folates stimulate growth and budding of Candida glabrata

Microbial Cell, 2015
Folate, vitamin B9, is well recognized as being essential for cell growth. The utilization of folate is common to all cells, but the source of it may be quite different. For example, mammalian cells depend on exogenous uptake of folates, while
