The subject invention relates to a process of preparing (R)-3-hydroxybutyric acid or a salt thereof by one-step fermentation with a nonpathogenic microorganism. The fermentation of (R)-3-hydroxybutyric acid was performed by supplying with certain carbon and nitrogen sources. These microorganisms include a Glutamic acid Bacterium HR057 strain or one type of genetically engineered Corynebacterium Glutamicum.

Processes are disclosed for preparing carboxylic acids from organic esters, the processes comprising contacting an ester with water in the presence of an acid catalyst and a homogenizing solvent at conditions effective to form a carboxylic acid. The homogenizing solvent is present in an amount sufficient to form a single-phase reaction mixture comprising the ester, water, and homogenizing solvent. The homogenizing solvent may be selected from acetonitrile, dimethyl sulfoxide, and 1,4-dioxane.
