Abstract
l-glutathione (GSH) is an important tripeptide compound with extensive applications in medicine, food additives, and cosmetics industries. In this work, an innovative whole-cell catalytic strategy was developed to enhance GSH production by combining metabolic engineering of GSH biosynthetic pathways with an adenosine-based adenosine triphosphate (ATP) regeneration system in Escherichia coli. Concretely, to enhance GSH production in E. coli, several genes associated with GSH and l-cysteine degradation, as well as the branched metabolic flow, were deleted. Additionally, the GSH bifunctional synthase (GshFSA) and GSH ATP-binding cassette exporter (CydDC) were overexpressed. Moreover, an adenosine-based ATP regeneration system was first introduced into E. coli to enhance GSH biosynthesis without exogenous ATP additions. Through the optimization of whole-cell catalytic conditions, the engineered strain GSH17-FDC achieved an impressive GSH titer of 24.19 g/L only after 2 h reaction, with a nearly 100% (98.39%) conversion rate from the added l-Cys. This work not only unveils a new platform for GSH production but also provides valuable insights for the production of other high-value metabolites that rely on ATP consumption.

Abstract
The efficient asymmetric bio-synthesis of chiral β-hydroxy esters is of great importance for industrial production. In this work, a simple and productive engineered E.coli cell-immobilized strategy was applied for the asymmetric reduction of MAA to (R)-HBME with high enantioselectivity. Compared with the corresponding inactivated free cells, the alginate-immobilized cells remained 45% of initial activity at 50 ℃ and 65% after reuse of 10 times. After 60 days of storage at 4 ℃, the immobilized cells maintained more than 80% relative activity. Immobilization contributed significantly to the improvement of thermal stability, pH tolerance, storage stability and operation stability without affecting the yield of product. The immobilized recombinant E. coli cell had absolute enantioselectivity for the asymmetric reduction of MAA to (R)-HBME with e.e. > 99.9%. Therefore, microbial cell immobilization is a perspective approach in asymmetric synthesis of chiral β-hydroxy esters for industrial applications.

Abstract
Asymmetric bioreduction of ketones is a fundamental process in the production of organic molecules. Compounds containing tetralone rings are found in the structure of many biologically active and pharmaceutical molecules. Biocatalytic reduction of ketones is one of the most promising and significant routes to prepare optically active alcohols. In this study, the reductive capacity of Lactobacillus paracasei BD101 was investigated as whole-cell biocatalyst in the enantioselective reduction of 1-tetralone (1). In biocatalytic reduction reactions, the conversion of the substrate and the enantiomeric excess (ee) of the product are significantly affected by optimization parameters such as temperature, agitation rate, pH, and incubation time. Effects of these parameters on ee and conversion were investigated comprehensively. (R)-1-tetralol ((R)-2), which can be used to treat disorder such as obsessive compulsive, post-traumatic stress, premenstrual dysphoric, and social anxiety, was manufactured in enantiopure form, high yield and gram-scale, using whole-cell biocatalysts of L. paracasei BD101. The 7.04 g of (R)-2 was obtained in optically pure form with 95% yield. Also, to our knowledge, this is the first report on production of (R)-2 using whole-cell biocatalyst in excellent yield, conversion, enantiopure form and gram scale. This is a clean, eco-friendly and cheap method for the synthesis of (R)-2 compared with chemical catalyst.

Abstract
Enzyme clustering into compact agglomerates could accelerate the processing of intermediates to enhance metabolic pathway flux. However, enzyme clustering is still a challenging task due to the lack of universal assembly strategy applicable to all enzymes. Therefore, we proposed an alternative enzyme assembly strategy based on functional inclusion bodies. First, functional inclusion bodies in cells were formed by the fusion expression of stomatin/prohibitin/flotillin/HflK/C (SPFH) domain and enhanced green fluorescent protein, as observed visually and by transmission electron microscopy. The formation of SPFH-induced functional inclusion bodies enhanced intermolecular polymerization as revealed by further analysis combined with Förster resonance energy transfer and bimolecular fluorescent complimentary. Finally, the functional inclusion bodies significantly improved the enzymatic catalysis in living cells, as proven by the examples with whole-cell biocatalysis of phenyllactic acid by Escherichia coli, and the production of N-acetylglucosamine by Bacillus subtilis. Our findings suggest that SPFH-induced functional inclusion bodies can enhance the cascade reaction of enzymes, to serve as a potential universal strategy for the construction of efficient microbial cell factories.
