Abstract
Target reaction-oriented screening from soil samples yielded a ketone reductase-producing Bacillus sp., strain ECU0013, which exhibits excellent stereoselectivity, high substrate tolerance and is capable of regenerating the required cofactor with glucose as a co-substrate. Whole-cells catalyzed the asymmetric reduction of 2-chloro-1-phenylethanone (50mM) to (R)-2-chloro-1-phenylethanol with a 93.3% conversion rate and 99% e.e. (enantiomeric excess). A variety of ketones were enantioselectively reduced by resting cells, giving corresponding chiral alcohols with good to excellent e.e. values. These results suggest the potential of this strain for the industrial production of chiral halogenated aromatic alcohols.

Abstract
3-Chloro-1-phenyl-1-propanol is used as a chiral intermediate in the synthesis of antidepressant drugs. Various microbial reductases were expressed in Escherichia coli, and their activities toward 3-chloro-1-phenyl-1-propanone were evaluated. The yeast reductase YOL151W (GenBank locus tag) exhibited the highest level of activity and exclusively generated the (S)-alcohol. Recombinant YOL151W was purified by Ni-nitrilotriacetic acid (Ni-NTA) and desalting column chromatography. It displayed an optimal temperature and pH of 40 degrees C and 7.5-8.0, respectively. The glucose dehydrogenase coupling reaction was introduced as an NADPH regeneration system. NaOH solution was occasionally added to maintain the reaction solution pH within the range of 7.0-7.5. By using this reaction system, the substrate (30 mM) could be completely converted to the (S)-alcohol product with an enantiomeric excess value of 100%. A homology model of YOL151W was constructed based on the structure of Sporobolomyces salmonicolor carbonyl reductase (Protein Data Bank ID: 1Y1P). A docking model of YOL151W with NADPH and 3-chloro-1-phenyl-1-propanone was then constructed, which showed that the cofactor and substrate bound tightly to the active site of the enzyme in the lowest free energy state and explained how the (S)-alcohol was produced exclusively in the reduction process.

Abstract
(S)-4-Chloro-3-hydroxybutyrate (CHB) is essential for the synthesis of biologically and pharmacologically important compounds. Rhizobium sp. DS-S-51 isolated from soil samples showed hydrolytic activity toward (R)-CHB in the racemate to (R)-3-hydroxy-gamma-butyrolactone (HL) under a simple composition of the reaction. Residual (S)-CHB was obtained with high optical purity. The gene encoding the enzyme concerned, designated CHB hydrolase, was isolated from DS-S-51, and the gene was highly expressed in Escherichia coli JM109. When the resolution of racemic methyl CHB (CHBM) as a substrate was performed using this recombinant cell, JM109 (pKK-R1), the hydrolytic activity was found to be 40-fold greater than that of DS-S-51, and the maximum concentration of the substrate added increased 2-fold. Moreover, (R)-HL was also obtained without decreasing the optical purity compared with that when (R)-CHBM was used as a substrate.

Abstract
A novel short-chain alcohol dehydrogenase from Paracoccus pantotrophus DSM 11072, which is applicable for hydrogen transfer, has been identified, cloned, and overexpressed in E. coli. The enzyme stereoselectively reduces several ketones in a sustainable substrate-coupled approach using 2-propanol (5% v/v) as hydrogen donor. The enzyme maintained its activity in organic co-solvents in biphasic as well as monophasic systems and was even active in micro-aqueous media (1% v/v aqueous buffer). In general, a higher conversion was observed at higher log P values of the solvent, however, DMSO, which exhibits the lowest log P value of all solvents investigated, was not only tolerated but led to a higher conversion and relative activity (110-210%). For example, the conversion after 24 h in 15% v/v DMSO was double that for the reaction performed in buffer. This tolerance to DMSO may be attributed to the ability of the wild-type strain to adapt and grow in media with high sulfur content.

Abstract
Phenylacetaldehyde reductase (PAR) from Rhodococcus sp. ST-10 is useful for chiral alcohol production because of its broad substrate specificity and high stereoselectivity. The conversion of ketones into alcohols by PAR requires the coenzyme NADH. PAR can regenerate NADH by oxidizing additional alcohols, especially 2-propanol. However, substrate conversion by wild-type PAR is suppressed in concentrated 2-propanol. Previously, we developed the Sar268 mutant of PAR, which can convert several substrates in the presence of concentrated 2-propanol. In this paper, further mutational engineering of Sar268 was performed to achieve higher process yield. Each of nine amino acid positions that had been examined for generating Sar268 was subjected to saturation mutagenesis. Two novel substitutions at the 42nd amino acid position increased m-chlorophenacyl chloride (m-CPC) conversion. Moreover, several nucleotide substitutions identified from libraries of random mutations around the start codon also improved the PAR activity. E. coli cells harboring plasmid pHAR1, which has the integrated sequence of the top clones from the above selections, provided greater conversion of m-CPC and ethyl 4-chloro-3-oxobutanoate than the Sar268 mutant, with very high optical purity of products. This mutant is a promising novel biocatalyst for efficient chiral alcohol production.

Abstract
Biocatalytic racemization of aliphatic and aryl-aliphatic sec-alcohols and alpha-hydroxyketones (acyloins) was accomplished using whole resting cells of bacteria, fungi, and one yeast. The mild (physiological) reaction conditions ensured the suppression of undesired side reactions, such as elimination or condensation. Cofactor and inhibitor studies suggest that the racemization proceeds through an equilibrium-controlled enzymatic oxidation-reduction sequence via the corresponding ketones or alpha-diketones, respectively, which were detected in various amounts. Ketone formation could be completely suppressed by exclusion of molecular oxygen. Figure Biocatalytic racemization whole microbial cells.

Abstract
An asymmetric hydrogen-transfer biocatalyst consisting of mutated Rhodococcus phenylacetaldehyde reductase (PAR) or Leifsonia alcohol dehydrogenase (LSADH) was applied for some water-soluble ketone substrates. Among them, 4-hydroxy-2-butanone was reduced to (S)/(R)-1,3-butanediol, a useful intermediate for pharmaceuticals, with a high yield and stereoselectivity. Intact Escherichia coli cells overexpressing mutated PAR (Sar268) or LSADH were directly immobilized with polyethyleneimine or 1,6-diaminehexane and glutaraldehyde and evaluated in a batch reaction. This system produced (S)-1,3-butanediol [87% enantiomeric excess (e.e.)] with a space time yield (STY) of 12.5 mg h(-1) ml(-1) catalyst or (R)-1,3-butanediol (99% e.e.) with an STY of 60.3 mg h(-1) ml(-1) catalyst, respectively. The immobilized cells in a packed bed reactor continuously produced (R)-1,3-butanediol with a yield of 99% (about 49.5 g/l) from 5% (w/v) 4-hydroxy-2-butanoate over 500 h.

Abstract
In our effort to search for effective carbonyl reductases, the activity and enantioselectivity of a carbonyl reductase from Sporobolomyces salmonicolor have been evaluated toward the reduction of a variety of ketones. This carbonyl reductase (SSCR) reduces a broad spectrum of ketones including aliphatic and aromatic ketones, as well as alpha- and beta-ketoesters. Among these substrates, SSCR shows highest activity for the reduction of alpha-ketoesters. Aromatic alpha-ketoesters are reduced to (S)-alpha-hydroxy esters, while (R)-enantiomers are obtained from the reduction of aliphatic counterparts. This interesting observation is consistent with enzyme-substrate docking studies, which show that hydride transfer occurs at the different faces of carbonyl group for aromatic and aliphatic alpha-ketoesters. It is worthy to note that sterically bulky ketone substrates, such as 2'-methoxyacetophenone, 1-adamantyl methyl ketone, ethyl 4,4-dimethyl-3-oxopentanoate and ethyl 3,3-dimethyl-2-oxobutanoate, are reduced to the corresponding alcohols with excellent optical purity. Thus, SSCR possesses an unusually broad substrate specificity and is especially useful for the reduction of ketones with sterically bulky substituents.

Abstract
Employing the over-expressed highly organic solvent tolerant alcohol dehydrogenase ADH-'A' from Rhodococcus ruber DSM 44541, versatile building blocks, which were not accessible by the wild type catalyst, were obtained in > 99% e.e.; furthermore, employing d8-2-propanol as deuterium source, stereoselective biocatalytic deuterium transfer was made feasible to furnish enantiopure deuterium labeled sec-alcohols on a preparative scale employing a single enzyme.
