A process for manufacturing pullulan, comprising:
- a. preparing a fermentation medium comprising water, a nitrogen source, a carbon source, a phosphate source, and a magnesium source;
- b. inoculating said fermentation medium with a pullulan producing microorganism;
- c. culturing said microorganism in said fermentation medium so as to produce pullulan in said fermentation medium;
- wherein said phosphate source comprises calcium phosphate and the pullulan has a ratio of (Mg2++Ca2+)/K+ greater than 5.

Pullulan produced by:
- preparing a fermentation medium comprising water, a nitrogen source, a carbon source, a phosphate source comprising calcium phosphate, and a magnesium source;
- inoculating the fermentation medium with a pullulan producing microorganism;
- and
- culturing the microorganism in the fermentation medium to produce the pullulan, the pullulan having a ratio of (Mg2++Ca2+)/K+ greater than 5.
1 more element
Pullulan having a Ca2+ content of at least 50 mg/kg and a ratio of (Mg2++Ca2+)/K+ greater than 5.
Pullulan having a Mg2+ content of at least 10 mg/kg and a ratio of (Mg2++Ca2+)/K+ greater than 5.
