Curr Microbiol 2024; 81:67. [PMID: 38236425 PMCID: PMC10796475 DOI: 10.1007/s00284-023-03577-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 11/29/2023] [Indexed: 01/19/2024]
Abstract
The development of green catalysts, specifically biocatalysts, is crucial for building a sustainable society. To enhance the versatility of biocatalysts, the immobilization of enzymes plays a vital role as it improves their recyclability and robustness. As target enzymes to immobilize, glucose dehydrogenases and carboxylases are particularly important among various kinds of enzymes due to their involvement in two significant reactions: regeneration of the reduced form of coenzyme required for various reactions, and carboxylation reactions utilizing CO2 as a substrate, respectively. In this study, we immobilized Thermoplasma acidophilum glucose dehydrogenase (TaGDH) and T. acidophilum isocitrate dehydrogenase (TaIDH) using a previously reported method involving the formation of enzyme-inorganic hybrid nanocrystals, in the course of our continuing study focusing on carboxylation catalyzed by the free form of TaGDH and TaIDH. Subsequently, we investigated the properties of the resulting immobilized enzymes. Our results indicate the successful immobilization of TaGDH and TaIDH through the formation of hybrid nanocrystals utilizing Mn2+. The immobilization process enhanced TaIDH activity, up to 211%, while TaGDH retained 71% of its original activity. Notably, the immobilized TaGDH exhibited higher activity at temperatures exceeding 87 °C than the free TaGDH. Moreover, these immobilized enzymes could be recycled. Finally, we successfully utilized the immobilized enzymes for the carboxylation of 2-ketoglutaric acid under 1 MPa CO2. In conclusion, this study represents the first immobilization of TaGDH and TaIDH using the hybrid nanocrystal forming method. Furthermore, we achieved significant activity enhancement of TaIDH through immobilization and demonstrated the recyclability of the immobilized enzymes.

Abstract
Dehydrogenases from fungi are attracting attention as industrial biocatalysts due to their high activity and chiral selectivity. However, these enzymes form insoluble aggregates when overexpressed in E. coli, limiting their industrial application. In the present study, we report the systematic development of a refolding process for selected, industrially relevant fungal dehydrogenases, viz., formate dehydrogenase from Candida boidinii (CbFDH) and formate and alcohol dehydrogenases from Geotrichum candium (GcFDH and GcADH, respectively). We first employed a screen to evaluate the effects of different variables on refolding including the buffer system, additives, and rate of dilution. The extent of refolding was determined by enzyme assays, circular dichroism, and tryptophan fluorescence. Our results showed that glycerol and reducing environment are essential for refolding of these dehydrogenases. Further, slow dilution of solubilized protein over 16 h dramatically improved the recovery of refolded enzymes compared to rapid dilution. The importance of slow dilution was further confirmed in a 10-fold scaled-up refolding trial. Overall, we demonstrate a robust method for refolding of fungal dehydrogenases, thus improving their availability for various biocatalytic applications.

Abstract
(R)-1-(4-methoxyphenyl) ethanol [(R)-1b] is an essential precursor for the synthesis of aryl propanoic acids' anti-inflammatatory drugs. Biocatalysts for (R)-1b preparation are limited and reductase has problems of low substrate concentration and low conversion rate. As a result, there is a constant need for discovering novel biocatalysts with excellent catalytic performances. In this study, a novel reductase LpSDR from Lacisediminihabitans profunda for the biocatalytic reduction of p-methoxyacetophenone (1a) to (R)-1b was obtained based on gene-mining technology, and some key reaction parameters were also investigated to improve the conversion rate of 1a using whole cells of recombinant Escherichia coli expressing reductase LpSDR as biocatalysts. It was found that the optimal concentration of isopropanol, ZnSO4·7H2O solution, 1a, and recombinant E. coli resting cells, the optimal reaction temperature, buffer pH, and reaction time were 1.95 mol l-1, 0.75 mmol l-1, 75 mmol l-1, 250 g (wet weight) l-1, 28°C, 7.0, and 21 h, respectively. Under the above conditions, a conversion rate of 99.5% and an enantiomeric excess of 99.6% were obtained, which were superior to the corresponding values previously reported. This study provides a novel reductase LpSDR, which is helpful in reducing 1a to (R)-1b.

Abstract
Fungi make a fundamental contribution to several biotechnological processes, including brewing, winemaking, and the production of enzymes, organic acids, alcohols, antibiotics, and pharmaceuticals. The present review explores the biotechnological importance of the filamentous yeast-like fungus Geotrichum candidum, a ubiquitous species known for its use as a starter in the dairy industry. To uncover G. candidum's biotechnological role, we performed a search for related work through the scientific indexing internet services, Web of Science and Google Scholar. The following query was used: Geotrichum candidum, producing about 6500 scientific papers from 2017 to 2022. From these, approximately 150 that were associated with industrial applications of G. candidum were selected. Our analysis revealed that apart from its role as a starter in the dairy and brewing industries, this species has been administered as a probiotic nutritional supplement in fish, indicating improvements in developmental and immunological parameters. Strains of this species produce a plethora of biotechnologically important enzymes, including cellulases, β-glucanases, xylanases, lipases, proteases, and α-amylases. Moreover, strains that produce antimicrobial compounds and that are capable of bioremediation were identified. The findings of the present review demonstrate the importance of G. candidum for agrifood- and bio-industries and provide further insights into its potential future biotechnological roles.

Abstract
OBJECTIVE A novel biocatalyst for Baeyer-Villiger oxidations is necessary for pharmaceutical and chemical industries, so this study aims to find a Baeyer-Villiger monooxygenase (BVMO) and to improve its stability by immobilization. RESULTS Acetone, the simplest ketone, was selected as the only carbon source for the screening of microorganisms with a BVMO. A eukaryote, Fusarium sp. NBRC 109816, with a BVMO (FBVMO), was isolated from a soil sample. FBVMO was overexpressed in E. coli and successfully immobilized by the organic-inorganic nanocrystal formation method. The immobilization improved the thermostability of FBVMO. Substrate specificity investigation revealed that both free and immobilized FBVMO were found to show catalytic activities not only for Baeyer-Villiger oxidation of ketones to esters but also for oxidation of sulfides to sulfoxides. Furthermore, a preparative scale reaction using immobilized FBVMO was successfully conducted. CONCLUSIONS FBVMO was discovered from an environmental sample, overexpressed in E. coli, and immobilized by the organic-inorganic nanocrystal formation method. The immobilization successfully improved its thermostability.
