||Vagabov VM, Trilisenko LV, Kulaev IS. Dependence of inorganic polyphosphate chain length on the orthophosphate content in the culture medium of the yeast Saccharomyces cerevisiae. Biochemistry (Mosc). 2000 Mar65(3):349-54.PubMed ID10739478
||The yeast is first cultivated for 4 h in a complete Rider medium containing 9 mM Pi and 111 mM glucose as a carbon source. Then the cells are placed on the same medium except depleted of Pi under sterile conditions and the culture is grown during 7 h. Further, the cells are again placed on fresh complete medium, where the culture is growing for 2 and 4 h
||The polyP3 fraction is involved in the maintenance of the fine structural organization of the yeast cell wall. This suggests that the cells primarily restore normal function of the cell surface disrupted during the phosphate starvation.
