Claims
- 1. A biologically pure culture of Aureobasidium sp. SN-124A strain (FERM BP-1429) and artificial mutants thereof, which have the properties of forming and accumulating erythritol in a culture solution when aerobically cultured on a liquid culture medium containing an assimilable carbon source and an assimilable nitrogen source, and are capable of preparing erythritol by fermentation of sugars.
- 2. A biologically pure culture strain of an artificial mutant of Aureobasidium sp. SN-124A strain (BP-1429), which has the properties of forming and accumulating erythritol in a culture solution without any substantial occurrence of foams due to fermentation when aerobically cultured on a liquid medium containing an assimilable carbon source in an amount of at least 40% and an assimilable nitrogen source, produce hydrophilic cells, and is capable of preparing erythritol by fermentation of sugars.
- 3. The biologically pure culture strain as defined in claim 1, in which said artificial mutant of Aureobasidium sp. SN-124A strain is Aureobasidium sp. SN-G42 strain
- 4. The biological pure culture strain as defined in claim 3, in which said artificial mutant of Aureobasidium sp. SN-124A strain is Aureobasidium sp. SN-.gamma.96 strain (FERM BP-1431).
