Screening, Identification, and Fermentation Condition Optimization of a High-Yield 3-Methylthiopropanol Yeast and Its Aroma-Producing Characteristics.

A high-yield 3-methylthiopropanol (3-Met) yeast Y1402 was obtained from sesame-flavored Daqu, and it was identified as . Y1402 showed a broad range of growth temperatures and pH, as well as the maximum tolerance to glucose, NaCl, nicotine, and 3-Met at 50% (/), 15% (/), 1.2 g/L, and 18 g/L, respectively.

Screening of Yeasts Isolated from Environments for Producing 3-Methylthio-1-propanol and Optimizing Production Conditions.

3-Methylthio-1-propanol (3-Met) is widely used as a flavoring substance and an essential aroma ingredient in many foods. Producing 3-Met by microbial transformation is green and eco-friendly. In the present study, one strain, YHM-G, which produced a high level of 3-Met, was isolated from the -producing environment.

Isolation and Identification of a High-Yield Ethyl Caproate-Producing Yeast From and Optimization of Its Fermentation.

is an important fermented product in China. A yeast named YX3307 that is capable of producing a large amount of ethyl caproate (EC) was isolated from , a crude fermentation starter for . This yeast was identified as on the basis of its morphological properties, physiological and biochemical characteristics, and 26S rDNA sequence.

Screening of yeasts isolated from environments for 2-phenylethanol production and optimization of production conditions.

2-Phenylethanol (2-PE) with a pleasant rose-like odor is a valuable aroma compound used in many fields. 2-PE production by yeast is considered a promising alternative to chemical synthesis and extraction from natural materials. In this report, the strain YF1702 produced a significantly higher level of 2-PE when compared with other strains isolated from -producing environments.
