Abstract: The present application provides a culture medium for producing ?-glucan. The culture medium comprises: a carbon source, lecithin and an ascorbic acid. The present application further provides a method for producing ?-glucan, the method comprising culturing Aureobasidium pullulans in the culture medium for fermentation. The Aureobasidium pullulans is advantageous in producing no melanin; as a result, the yield of ?-glucan can be increased and the waste can be reduced with the improved culture medium composition and culturing method. A biological sample of the Aureobasidium pullulans described in the present specification is deposited at National Institute of Technology and Evaluation (NITE), NITE Patent Microorganisms Depositary (NPMD) on Oct. 19, 2016 under the access number NITE BP-02372.

Abstract: A method of producing erythritol. The method includes growing in a culture an isolated yeast strain that possesses certain unique characteristics and is capable of converting glucose to erythritol in a glucose-containing medium, and purifying erythritol from the culture.

Abstract: A yeast strain capable of converting glucose to erythritol, said strain having the following identifying characteristics: an absence of motile spores; septate mycelia; asexual reproduction; an absence of reniform cells; conidia optionally formed on short denticles but not on elongate stalks; an absence of ballistoconidia; non-monopolar budding on a broad base; acropetal chains of blastoconidia; dark brown, thick-walled chlamydospores; an ability to assimilate sucrose, glycerol and maltose; an inability to assimilate lactose; an inability to ferment galactose; an ability to grow in a vitamin-free medium; and an ability to grow at 25° C. to 36° C.
