Abstract. In recent years the usefulness of enzymatic systems to obtain a single stereoisomerically pure compound starting from a racemate has been expanded. Moreover, current advances in protein engineering, molecular biology and modeling tools are the basis to improve the catalytic properties of enzymes to face novel synthetic challenges. Also, medium engineering and novel immobilization methods of (bio)catalysts are enhancing the productivity of biocatalytic processes making them suitable for being scalable. The development of multienzymatic protocols and the combination of enzymes with other catalysts are providing a wide range of synthetic possibilities that are expanding the scope of these transformations even at industrial scale. Herein we will describe an overview of recent (chemo)enzymatic deracemizations, focusing on the strategy employed (dynamic kinetic resolution, stereoinversion, cyclic deracemization or enantioconvergent process), the type of substrate (e.g., alcohols, amines, carboxylic acid derivatives or carbonylic compounds), and the biocatalyst(s) used.

Metschnikowia, the single-cell yeast form, is a genus of 85 species in the Saccharomycetales order that developed in both aquatic and terrestrial ecosystems after being found in 1899. This yeast is commonly used to control microbial populations in many biological and artificial conditions, such as fermentation. However, current study of Metschnikowia is limited to biological control features rather than researching on lucrative sectors such as beverage production, bioconversion manufacturing, cosmetics, and the pharmaceutical industry. This review summarizes numerous possible applications of Metschnikowia in human life, including potential secondary metabolites in industrial fields such as cosmetics and pharmaceuticals. Furthermore, Metschnikowia-yeast interaction is mentioned as a potential area for further exploration in terms of co-cultured microbes as biocontrol. Since Metschnikowia yeast arose in a variety of ecosystems, more discussion will be held regarding the interactions between Metschnikowia and their surroundings, particularly in fruits. Finally, the current regulatory challenges of Metschnikowia-based products are examined, and future research opportunities on Metschnikowia utilization are presented. Key points • Utilization of Metschnikowia genus in various human aspects. • Promising secondary metabolites produced by Metschnikowia. • Challenge and opportunity on developing Metschnikowia-based products.

From comparisons of ITS1-5.8S-ITS2 and gene sequences for nuclear D1/D2 LSU rRNA, nuclear SSU (18S) rRNA, translation elongation factor 1-α (EF1-α) and RNA polymerase II subunit 2 (RPB2), the following four new ascosporogenous yeast species were resolved and are described as Metschnikowia anglica (NRRL Y-7298 [type strain], CBS 15342, MycoBank MB 823167), Metschnikowia leonuri (NRRL Y-6546, CBS 15341, MB 823166), Metschnikowia peoriensis (NRRL Y-5942, CBS 15345, MB 823164) and Metschnikowia rubicola (NRRL Y-6064, CBS 15344, MB 823165). The following six species of Candida are members of the Metschnikowia clade and are proposed for transfer to Metschnikowia as new combinations: Candida chrysomelidarum (NRRL Y-27749, CBS 9904, MB 823223), Candida gelsemii (NRRL Y-48212, CBS 10509, MB 823192), Candida kofuensis (NRRL Y-27226, CBS 8058, MB 823195), Candida picachoensis (NRRL Y-27607, CBS 9804, MB 823197), Candida pimensis (NRRL Y-27619, CBS 9805, MB 823205) and Candida rancensis (NRRL Y-48702, CBS 8174, MB 823224). Candida fructus (NRRL Y-17072, CBS 6380, MB 823206) is transferred to Clavispora as a new combination, and Candida musae is shown to be a synonym of C. fructus. Apparent multiple alleles for ITS, D1/D2, EF1-α and RPB2 were detected in strains of some species.
