Abstract
Patulin is a mycotoxin that primarily contaminate apples and apple products. Whole cell or cell-free extracts of Gluconobacter oxydans ATCC 621 were able to transform patulin to E-ascladiol. Proteins from cell-free extracts were separated by anion exchange chromatography and fractions with patulin transformation activity were subjected to peptide mass fingerprinting, enabling the identification of two NADPH dependent short chain dehydrogenases, GOX0525 and GOX1899, with the requisite activity. The genes encoding these enzymes were expressed in E. coli and purified. Kinetic parameters for patulin reduction, as well as pH profiles and thermostability were established to provide further insight on the potential application of these enzymes for patulin detoxification.

Enzyme Microb Technol 2020; 141:109670.

Abstract
6-(N-hydroxyethyl)-amino-6-deoxy-l-sorbofuranose (6NSL), a key precursor in the synthesis of miglitol, is produced from N-2-hydroxyethyl-glucamine (NHEG) by the regioselective oxidation of Gluconobacter oxydans. The limitation of PQQ biosynthesis became a bottleneck for improvement of PQQ-dependent D-sorbitol dehydrogenase (mSLDH) activity. Five expression plasmids were constructed for the co-expression of the pqqABCDE gene cluster and the tldD gene on the basis of pBBR1-gHp0169-sldAB in G. oxydans to increase the biosynthesis of PQQ. The G. oxydans/pGA004, in which pqqABCDE and tldD were expressed as a cluster under the control of gHp0169 promoter, showed the optimal performance. The intracellular PQQ concentration and specific activity of mSLDH in cells increased by 79.3 % and 53.7 %, respectively, compared to that in G. oxydans/pBBR-sldAB. Then, the repeated batch biotransformation of NHEG to 6NSL by G. oxydans/pGA004 was carried out. Up to 75.0 ± 3.0 g/L of 6NSL production with 94.5 ± 3.6 % of average conversion rate of NHEG to 6NSL was achieved after four cycles of run. These results indicated that G. oxydans/pGA004 with high productivity had great potential for 6NSL production in industrial bioprocess.

Abstract
Chiral aromatic alcohols have received much attention due to their widespread use in pharmaceutical industries. In the asymmetric synthesis processes, the excellent performance of alcohol dehydrogenase makes it a good choice for biocatalysts. In this study, a novel and robust medium‐chain alcohol dehydrogenase RhADH from Rhodococcus R6 was discovered and used to catalyse the asymmetric reduction of aromatic ketones to chiral aromatic alcohols. The reduction of 2‐hydroxyacetophenone (2‐HAP) to (R)‐(‐)‐1‐phenyl‐1,2‐ethanediol ((R)‐PED) was chosen as a template to evaluate its catalytic activity. A specific activity of 110 U mg−1 and a 99% purity of e.e. was achieved in the presence of NADH. An efficient bienzyme‐coupled catalytic system (RhADH and formate dehydrogenase, CpFDH) was established using a two‐phase strategy (dibutyl phthalate and buffer), which highly raised the tolerated substrate concentration (60 g l−1). Besides, a broad range of aromatic ketones were enantioselectively reduced to the corresponding chiral alcohols by this enzyme system with highly enantioselectivity. This system is of the potential to be applied at a commercial scale.

Abstract
(R)-1-phenyl-1,2-ethanediol is an important synthon for the preparation of β-adrenergic blocking agents. This study identified a (2R,3R)-butanediol dehydrogenase (KgBDH) from Kurthia gibsonii SC0312, which showed high enantioselectivity for production of (R)-1-phenyl-1,2-ethanediol by reduction of 2-hydroxyacetophenone. KgBDH was expressed in a recombinant engineered strain, purified, and characterized. It showed good catalytic activity at pH 6–8 and better stability in alkaline (pH 7.5–8) than an acidic environment (pH 6.0–7.0), providing approximately 73 and 88% of residual activity after 96 h at pH 7.5 and 8.0, respectively. The maximum catalytic activity was obtained at 45°C; nevertheless, poor thermal stability was observed at >30°C. Additionally, the examined metal ions did not activate the catalytic activity of KgBDH. A recombinant Escherichia coli strain coexpressing KgBDH and glucose dehydrogenase (GHD) was constructed and immobilized via entrapment with a mixture of activated carbon and calcium alginate via entrapment. The immobilized cells had 1.8-fold higher catalytic activity than that of cells immobilized by calcium alginate alone. The maximum catalytic activity of the immobilized cells was achieved at pH 7.5, and favorable pH stability was observed at pH 6.0–9.0. Moreover, the immobilized cells showed favorable thermal stability at 25–30°C and better operational stability than free cells, retaining approximately 55% of the initial catalytic activity after four cycles. Finally, 81% yields (195 mM product) and >99% enantiomeric excess (ee) of (R)-1-phenyl-1,2-ethanediol were produced within 12 h through a fed-batch strategy with the immobilized cells (25 mg/ml wet cells) at 35°C and 180 rpm, with a productivity of approximately 54 g/L per day.

Abstract
Gluconobacter oxydans plays an important role in the conversion of d-sorbitol to l-sorbose, which is an essential intermediate for the industrial-scale production of vitamin C. In the fermentation process, some d-sorbitol could be converted to d-fructose and other byproducts by uncertain dehydrogenases. Genome sequencing has revealed the presence of diverse genes encoding dehydrogenases in G. oxydans. However, the characteristics of most of these dehydrogenases remain unclear. Therefore, the analyses of these unknown dehydrogenases could be useful for identifying those related to the production of d-fructose and other byproducts. Accordingly, dehydrogenases in G. oxydans WSH-003, an industrial strain used for vitamin C production, were examined. A nicotinamide adenine dinucleotide (NAD)-dependent dehydrogenase, which was annotated as xylitol dehydrogenase 2, was identified, codon-optimized, and expressed in Escherichia coli BL21 (DE3) cells. The enzyme exhibited a high preference for NAD+ as the cofactor, while no activity with nicotinamide adenine dinucleotide phosphate, flavin adenine dinucleotide, or pyrroloquinoline quinone was noted. Although this enzyme presented high similarity with NAD-dependent xylitol dehydrogenase, it showed high activity to catalyze d-sorbitol to d-fructose. Unlike the optimum temperature and pH for most of the known NAD-dependent xylitol dehydrogenases (30-40 °C and about 6-8, respectively), those for the identified enzyme were 57 °C and 12, respectively. The values of K m and V max of the identified dehydrogenase toward l-sorbitol were 4.92 μM and 196.08 μM/min, respectively. Thus, xylitol dehydrogenase 2 can be useful for the cofactor-reduced nicotinamide adenine dinucleotide regeneration under alkaline conditions, or its knockout can improve the conversion ratio of d-sorbitol to l-sorbose.

Abstract
Background Acetobacter sp. CCTCC M209061 could catalyze carbonyl compounds to chiral alcohols following anti-Prelog rule with excellent enantioselectivity. Therefore, the enzymatic characterization of carbonyl reductase (CR) from Acetobacter sp. CCTCC M209061 needs to be investigated. Results A CR from Acetobacter sp. CCTCC M209061 (AcCR) was cloned and expressed in E. coli. AcCR was purified and characterized, finding that AcCR as a dual coenzyme-dependent short-chain dehydrogenase/reductase (SDR) was more preferred to NADH for biocatalytic reactions. The AcCR was activated and stable when the temperature was under 35 °C and the pH range was from 6.0 to 8.0 for the reduction of 4′-chloroacetophenone with NADH as coenzyme, and the optimal temperature and pH were 45 °C and 8.5, respectively, for the oxidation reaction of isopropanol with NAD+. The enzyme showed moderate thermostability with half-lives of 25.75 h at 35 °C and 13.93 h at 45 °C, respectively. Moreover, the AcCR has broad substrate specificity to a range of ketones and ketoesters, and could catalyze to produce chiral alcohol with e.e. >99% for the majority of tested substrates following the anti-Prelog rule. Conclusions The recombinant AcCR exhibited excellent enantioselectivity, broad substrate spectrum, and highly stereoselective anti-Prelog reduction of prochiral ketones. These results suggest that AcCR is a powerful catalyst for the production of anti-Prelog alcohols.The biocatalytic reactions conducted with the recombinant AcCR ![]()
