Abstract
Actinobacteria are one of the most intriguing bacterial phyla in terms of chemical diversity and bioactivities of their reported biomolecules and natural products, including various types of chiral molecules. Actinobacterial genera such as Detzia, Mycobacterium, and Streptomyces are among the microbial sources targeted for selective reactions such as asymmetric biocatalysis catalyzed by whole cells or enzymes induced in their cell niche. Remarkably, stereoselective reactions catalyzed by actinobacterial whole cells or their enzymes include stereoselective oxidation, stereoselective reduction, kinetic resolution, asymmetric hydrolysis, and selective transamination, among others. Species of actinobacteria function with high chemo-, regio-, and enantio-selectivity under benign conditions, which could help current industrial processing. Numerous selective enzymes were either isolated from actinobacteria or expressed from actinobacteria in other microbes and hence exploited in the production of pure organic compounds difficult to obtain chemically. In addition, different species of actinobacteria, especially Streptomyces species, function as natural producers of chiral molecules of therapeutic importance. Herein, we discuss some of the most outstanding contributions of actinobacteria to asymmetric biocatalysis, which are important in the organic and/or pharmaceutical industries. In addition, we highlight the role of actinobacteria as microbial cell factories for chiral natural products with insights into their various biological potentialities.

Appl Microbiol Biotechnol 2021; 105:3169-3180.

Abstract
Biocatalytic synthesis of pharmaco-chiral sulfoxides has gained interest in recent years for its environmental friendliness. However, only a few natural biocatalysts can be used for the efficient synthesis of pharmaco-sulfoxides, including (R)-lansoprazole, a chiral proton pump inhibitor used to treat gastrointestinal diseases. In this study, the sequence of BoBVMO (Baeyer-Villiger monooxygenase from Bradyrhizobium oligotrophicum) was used as a probe to identify BVMOs via genomic mining for the highly efficient synthesis of (R)-lansoprazole and other pharmaco-sulfoxides. After virtual sequence filtering, target gene cloning, heterologous expression, and activity screening for lansoprazole sulfide (LPS) monooxygenation, seven new BVMOs were identified among more than 10,000 homologous BVMOs. According to the conserved sequence and phylogenetic tree analysis, these discovered enzymes belong to the family of type I BVMOs and the ethionamide monooxygenase subtype. Among them, CbBVMO, Baeyer-Villiger monooxygenase from Cupriavidus basilensis, showed the highest efficiency and excellent enantioselectivity for converting LPS into (R)-lansoprazole. Moreover, CbBVMO showed a wide substrate spectrum toward other bulky prazole-family sulfides. The results indicate that CbBVMO is a potential enzyme for extending the application of BVMOs in pharmaceutical industry. KEY POINTS: • CbBVMO is the most efficient biocatalyst for (R)-lansoprazole biosynthesis. • CbBVMO catalyzes the conversion of various bulky prazole sulfides. • CbBVMO is a promising enzyme for the biosynthesis of pharmaco-sulfoxides.

Abstract
Cortisone is a steroid widely used as an anti-inflammatory drug able to suppress the immune system, thus reducing inflammation and attendant pain and swelling at the site of an injury. Due to its numerous side effects, especially in prolonged and high-dose therapies, the development of the pharmaceutical industry is currently aimed at finding new compounds with similar activities but with minor or no side effects. Biotransformations are an important methodology towards more sustainable industrial processes, according to the principles of "green chemistry". In this work, the biotransformation of cortisone with Rhodococcus rhodnii DSM 43960 to give two new steroids, i.e., 1,9β,17,21-tetrahydoxy-4-methyl-19-nor-9β-pregna-1,3,5(10)-trien-11,20-dione and 1,9β,17,20β,21-pentahydoxy-4-methyl-19-nor-9β-pregna-1,3,5(10)-trien-11-one, is reported. These new steroids have been fully characterized.

Abstract
Members of class VII cytochromes P450 are catalytically self-sufficient enzymes containing a phthalate dioxygenase reductase-like domain fused to the P450 catalytic domain. Among these, CYP116B46 is the first enzyme for which the 3D structure of the whole polypeptide chain has been solved, shedding light on the interaction between its domains, which is crucial for catalysis. Most of these enzymes have been isolated from extremophiles or detoxifying bacteria that can carry out regio- and enantioselective oxidation of compounds of biotechnological interest. Protein engineering has generated mutants that can perform challenging organic reactions such as the anti-Markovnikov alkene oxidation. This potential, combined with the detailed 3D structure, forms the basis for further directed evolution studies aimed at widening their biotechnological exploitation.

Abstract
Asymmetric oxidation of prochiral sulfides is a direct means for production of enantiopure sulfoxides which are important in organic synthesis and the pharmaceutical industry. In the present study, Streptomyces glaucescens GLA.0 was employed for stereoselective oxidation of prochiral sulfides. Growing cells selectively catalyzed the oxidation of phenyl methyl sulfide to the corresponding sulfoxide. Only very little overoxidation was observed, resulting in minor amounts of the unwanted sulfone. Addition of isopropyl alcohol as a co-solvent, time of substrate addition and composition of the reaction media resulted in enhanced phenyl methyl sulfide biotransformation. The concentration of the undesired by-product (sulfone) was as low as 4% through the reaction course under optimal reaction conditions. The results show that S. glaucescens GLA.0 is a promising whole-cell biocatalyst for preparing highly enantiopure (R)-phenyl methyl sulfoxide in high yield (90%) with an enantiomeric excess (ee) exceeding 99%. Application of Streptomyces glaucescens as a whole-cell oxidative biocatalyst without using an external cofactor.![]()

Abstract
Pharmaceutical effluents released from industries are accountable to deteriorate the aquatic and soil environment through indirect toxic effects. Microbes are adequately been used to biodegrade pharmaceutical industry wastewater and present study was envisaged to determine biodegradation of pharmaceutical effluent by Micrococcus yunnanensis. The strain showed 42.82% COD (Chemical oxygen demand) reduction before optimization. After applying Taguchi's L8 array as an optimization technique, the biodegradation rate was enhanced by 82.95% at optimum conditions (dextrose- 0.15%, peptone 0.1%, inoculum size 4% (wv-1), rpm 200, pH 8 at 25 °C) within 6 h. The confirmation of pharmaceuticals degradation was done by 1H NMR (Nuclear magnetic resonance) studies followed by elucidation of transformation pathways of probable drugs in the effluent through Q-Tof-MS (Quadrupole Time of Flight- Mass Spectrometry). The cytotoxicity evaluation of treated and untreated wastewater was analyzed on Human Embryonic Kidney (HEK 293) cells using Alamar Blue assay, which showed significant variance.

Abstract
Currently, the power and usefulness of biocatalysis in organic synthesis is undeniable, mainly due to the very high enantiomeric excess reached using enzymes, in an attempt to emulate natural processes. However, the use of isolated enzymes has some significant drawbacks, the most important of which is cost. The use of whole cells has emerged as a useful strategy with several advantages over isolated enzymes; for this reason, modern research in this field is increasing, and various reports have been published recently. This review surveys the most recent developments in the enantioselective reduction of carbon-carbon double bonds and prochiral ketones and the oxidation of prochiral sulfides using whole cells as biocatalytic systems.

Abstract
Biocatalysis is an emerging strategy for the production of enantio-pure organic molecules. However, lacking of commercially available enzymes restricts the widespread application of biocatalysis. In this study, we report a Pseudomonas strain which exhibited versatile oxidation activity to synthesize chiral sulfoxides when growing under M9-toluene medium and reduction activity to synthesize chiral alcohols when on Luria-Bertani (LB) medium, respectively. Further comparative transcriptome analysis on samples from these two cultural conditions has identified 1038 differentially expressed genes (DEG). Gene Ontology (GO) enrichment and KEGG pathways analysis demonstrate significant changes in protein synthesis, energy metabolism, and biosynthesis of metabolites when cells cultured under different conditions. We have identified eight candidate enzymes from this bacterial which may have the potential to be used for synthesis of chiral alcohol and sulfoxide chemicals. This work provides insights into the mechanism of diversity in catalytic properties of this Pseudomonas strain growth with different cultural conditions, as well as candidate enzymes for further biocatalysis of enantiomerically pure molecules and pharmaceuticals.

Abstract
Chiral organic sulfoxides (COSs) are important compounds that act as chiral auxiliaries in numerous asymmetric reactions and as intermediates in chiral drug synthesis. In addition to their optical resolution, stereoselective oxidation of sulfides can be used for COS production. This reaction is facilitated by oxygenases and peroxidases from various microbial resources. To meet the current demand for esomeprazole, a proton pump inhibitor used in the treatment of gastric-acid-related disorders, and the (S)-isomer of an organic sulfoxide compound, omeprazole, a successful biotechnological production method using a Baeyer-Villiger monooxygenase (BVMO), was developed. In this review, we summarize the recent advancements in COS production using biocatalysts, including enzyme identification, protein engineering, and process development.

Abstract
(S)-(+)-2,2-Dimethylcyclopropane carboxylic acid [(S)-(+)-DMCPA] is a key chiral intermediate for production of Cilastatin, an excellent renal dehydropeptidase-I inhibitor. In this study, a new method for preparation of (S)-(+)-DMCPA with microbial esterases was investigated. A microbial screening program obtained six esterase-producing isolates that could display relatively high activities and enantioselectivities using racemic ethyl 2,2-dimethylcyclopropane carboxylate (DMCPE) as screening substrate, aiming at forming optically pure (S)-(+)-DMCPA. Further selection was carried out with substrates having different alcohol moieties, including methyl, ethyl, and 2-chloroethyl esters. Finally, one of these strains, numbered ECU1013, with high enantioselectivity toward the hydrolytic resolution of methyl 2,2-dimethylcyclopropane carboxylate (DMCPM), afforded the (S)-product in 92 % ee, and was later identified as Rhodococcus sp. According to our research, there were several active esterases to DMCPM in cells of Rhodococcus sp. ECU1013; however, (S)-preferential esterase was selectively enriched based on the time-dependent profile of esterases biosynthesis, thereby the enantiomeric excess of biotransformation product (ee p) was constantly increased, finally maintained at 95 % (S). To improve the yield, various organic solvents were employed for better dispersion of the hydrophobic substrate. As a result, (±)-DMCPM of up to 400 mM in the organic phase of isooctane was enantioselectively hydrolyzed into (S)-(+)-DMCPA, with an isolation yield of 38 % and a further increase of ee p to 99 %.

Abstract
Production of enantiopure esomeprazole by biocatalysis is of great demand by pharmaceutical industry. A Gram-positive bacterium oxidizing omeprazole sulfide 1a (5-methoxy-2-[((4-methoxy-3,5-dimethylpyridin-2-yl)methyl)thio]-1H-benzoimidazole) to (S)-sulfoxide esomeprazole 2a (S)-5-methoxy-2-[(4-methoxy-3,5-dimethylpyridin-2-yl) methylsulfinyl]-3H-benzoimidazole was isolated from soil polluted with elemental sulfur. The strain exhibited the highest identity with the genus Lysinibacillus and catalyzed oxidation of 1a into enantiopure esomeprazole with conversion of 77% in a stirred bioreactor, fed-batch culture. No consecutive oxidation of (S)-sulfoxide to sulfone was observed during whole-cell catalysis. The unique characteristics of the catalyst provide a solid basis for further improvement and development of sustainable green bioprocess.

Abstract
Whole cells of Rhodococcus sp. ECU0066 were used a catalyst for resolution of racemic sulfoxides, as an alternative to asymmetric oxidation of sulfides for efficient production of enantiopure sulfoxides. Racemic sulfoxides were excellent substrates for biotransformation because of their lower biotoxicity compared to sulfides. Determination of apparent kinetic parameters indicated that phenyl methyl sulfide (PMS), but not racemic phenyl methyl sulfoxide (rac-PMSO) caused substrate inhibition. (S)-PMSO was formed at a higher concentration and good enantiomeric excess (37.8 mM and 93.7% ee(S)) in a fed-batch reaction, than by an asymmetric oxidation of PMS (10 mM and 80% eeP (S)). The bacterium also displayed fairly good activity (yields, 22.7-43.2%; within 1-8 h) and enantioselectivity (ee(S)>99.0%) towards para-substituted (methyl and chloro) phenyl methyl sulfoxides and ethyl phenyl sulfoxide, indicating it could be a promising agent for synthetic applications.

Abstract
A cytochrome P450 monooxygenase (P450SMO) from Rhodococcus sp. can catalyze asymmetric oxygenation of sulfides to S-sulfoxides. However, P450SMO-catalyzed biotransformations require a constant supply of NAD(P)H, the expense of which constitutes a great hindrance for this enzyme application. In this study, we investigated the asymmetric oxygenation of sulfide to S-sulfoxide using E. coli cells, which co-express both the P450SMO gene from Rhodococcus sp. and the glucose dehydrogenase (GDH) gene from Bacillus subtilis, as a catalyst. The results showed that the catalytic performance of co-expression systems was markedly improved compared to the system lacking GDH. When using recombinant E. coli BL21 (pET28a-P450-GDH) whole cell as a biocatalyst, NADPH was efficiently regenerated when glucose was supplemented in the reaction system. A total conversion of 100% was achieved within 12 h with 2 mM p-chlorothioanisole substrate, affording 317.3 mg/L S-sulfoxide obtained. When the initial sulfide concentration was increased to 5 mM, the substrate conversion was also increased nearly fivefold: S-sulfoxide amounted to 2.5 mM (396.6 mg/L) and the ee value of sulfoxide product exceeded 98%. In this system, the effects of glucose concentration and substrate concentration were further investigated for efficient biotransformation. This system is highly advantageous for the synthesis of optically pure S-sulfoxide.

Abstract
Escherichia coli BL21 as production strain for the production of cytochrome P450 monooxygenase (P450SMO) from Rhodococcus sp. in high yields was developed. The expression was first optimized with a series of flask experiments testing several key parameters for their influence on the expression level and enzyme activity. The optimal process parameters found in the flask experiments were verified in a cultivation process in a 5-L bioreactor. Glycerol proved to be superior over glucose as carbon source. Low dissolved oxygen (DO) concentration (<10%) during expression was found to be critical for active P450s production, resulting in expression level of 400 nM for P450SMO. Intact cells were used to establish an efficient bioconversion system for the production of sulfoxidation product. With p-chlorothioanisole as a representative substrate, the desired product (S-sulfoxide) was afforded with 99% ee and highest production of 130 mg/L within 12 h.

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
In this study, a 3.7-kb DNA fragment was cloned from Rhodococcus sp. ECU0066, and the sequence was analyzed. It was revealed that the largest one (2,361 bp) of this gene fragment encodes a protein consisting of 787 amino acids, with 73% identity to P450RhF (accession number AF45924) from Rhodococcus sp. NCIMB 9784. The gene of this new P450 monooxygenase (named as P450SMO) was successfully expressed in Escherichia coli BL21 (DE3), and the enzyme was also purified and characterized. In the presence of reduced nicotinamide adenine dinucleotide phosphate, the enzyme showed significant sulfoxidation activity towards several sulfides, with (S)-sulfoxides as the predominant product. The p-chlorothioanisole, p-fluorothioanisole, p-tolyl methyl sulfide, and p-methoxythioanisole showed relatively higher activities than the other sulfides, but the stereoselectivity for p-methoxythioanisole was much lower. The optimal activity of the purified enzyme toward p-chlorothioanisole occurred at pH 7.0 and 30 degrees C. The current study is the first to report a recombinant cytochrome P450 enzyme of Rhodococcus sp. which is responsible for the asymmetric oxidation of sulfides. The new enzymatic activity of P450SMO on the above compounds makes it an attractive biocatalyst for asymmetric synthesis of enantiopure sulfoxides.
