Surface Engineering of Escherichia coli to Display Its Phytase (AppA) and Functional Analysis of Enzyme Activities. Curr Issues Mol Biol 2024; 46:3424-3437.

Abstract
Escherichia coli phytase (AppA) is widely used as an exogenous enzyme in monogastric animal feed mainly because of its ability to degrade phytic acid or its salt (phytate), a natural source of phosphorus. Currently, successful recombinant production of soluble AppA has been achieved by gene overexpression using both bacterial and yeast systems. However, some methods for the biomembrane immobilization of phytases (including AppA), such as surface display on yeast cells and bacterial spores, have been investigated to avoid expensive enzyme purification processes. This study explored a homologous protein production approach for displaying AppA on the cell surface of E. coli by engineering its outer membrane (OM) for extracellular expression. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of total bacterial lysates and immunofluorescence microscopy of non-permeabilized cells revealed protein expression, whereas activity assays using whole cells or OM fractions indicated functional enzyme display, as evidenced by consistent hydrolytic rates on typical substrates (i.e., p-nitrophenyl phosphate and phytic acid). Furthermore, the in vitro results obtained using a simple method to simulate the gastrointestinal tract of poultry suggest that the whole-cell biocatalyst has potential as a feed additive. Overall, our findings support the notion that biomembrane-immobilized enzymes are reliable for the hydrolysis of poorly digestible substrates relevant to animal nutrition.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 901:166468. [PMID: 37619729 DOI: 10.1016/j.scitotenv.2023.166468] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/19/2023] [Revised: 07/11/2023] [Accepted: 08/19/2023] [Indexed: 08/26/2023]
Abstract
Phosphorus (P) is a limiting nutrient in the soil-plant nutrient cycling. Although the exogenous application of chemical P fertilizers can satisfy crop P requirements during critical growth phases. While excessive P fertilizers use results in low phosphorus acquisition efficiency (PAE), it has serious environmental consequences and hastens the depletion of P mineral reserves. Phosphate-solubilizing bacteria (PSB) have the potential to make insoluble phosphate available to plants through solubilization and mineralization, increasing crop yields while maintaining environmental sustainability. Existing reviews mainly focus on the beneficial effects of PSB on crop performance and related mechanisms, while few of them elucidate the action mechanisms of PSB in soil-microbe-plant interactions for crop cultivation with high yield efficiency. Hence, this study provides a comprehensive review of the physicochemical and molecular mechanisms (e.g., root exudates, extracellular polysaccharides, organic acids, phosphatases, and phosphate-specific transport systems) of PSB to facilitate the P cycle in the soil-plant systems. Further, the potential of commercial applications of PSB (e.g., genetic engineering, seed priming and coating) are also discussed in order to highlight their contribution to sustainable agriculture. Finally, existing challenges and future prospects in agricultural applications are proposed. In conclusion, we firmly believe that PSB represent a highly significant biotechnological tool for enhancing agricultural productivity and offers a wide range of extensive potential applications.

Abstract
In Bacillus, the spore formation process is associated with the synthesis and release of secondary metabolites. A large number of studies have been conducted to systematically elucidate the pathways and mechanisms of spore formation. However, there are no studies have explored the relationship between secondary metabolites and spores. In this study, we investigated the relationship between its secondary metabolite bacillomycin D (BD) and spores using the simpler dipicolonic acid fluorimetry assay for spore counting in Bacillus amyloliquefaciens fmbJ. Our results showed that BD could promote the spore formation of B. amyloliquefaciens fmbJ and had a synergistic effect with certain concentrations of Mn2+. When 15.6 mg/L of BD and 1 mM of Mn2+ were added, the number of fmbJ spores increased from 1.42 × 108 CFU/mL to 2.02 × 108 CFU/mL after 36 h of incubation. The expressions of spore formation (kinA, kinB, kinC, kinD, kinE and spo0A) and Mn-related genes (mntA, mntH, mneS, mneP) were studied by RT-PCR. The results indicated that BD and Mn2+ promoted the spore formation of fmbJ by stimulating the transcription of kinB, kinD and increasing the influence of spo0F-spo0A phosphorylation transmission. This study provided a new idea to improve the spore production of B. amyloliquefaciens and laid the foundation for its industrial production.

Abstract
Bacillus subtilis is a commonly used commercial specie with broad applications in the fields of bioengineering and biotechnology. B. subtilis is capable of producing both biofilms and spores. Biofilms are matrix-encased multicellular communities that comprise various components including exopolysaccharides, proteins, extracellular DNA, and poly-γ-glutamic acid. These biofilms resist environmental conditions such as oxidative stress and hence have applications in bioremediation technologies. Furthermore, biofilms and spores can be engineered through biotechnological techniques for environmentally-friendly and safe production of bio-products such as enzymes. The ability to withstand with harsh conditions and producing spores makes Bacillus a suitable candidate for surface display technology. In recent years, the spores of such specie are widely used as it is generally regarded as safe to use. Advances in synthetic biology have enabled the reprogramming of biofilms to improve their functions and enhance the production of value-added products. Globally, there is increased interest in the production of engineered biosensors, biocatalysts, and biomaterials. The elastic modulus and gel properties of B. subtilis biofilms have been utilized to develop living materials. This review outlines the formation of B. subtilis biofilms and spores. Biotechnological engineering processes and their increasing application in bioremediation and biocatalysis, as well as the future directions of B. subtilis biofilm engineering, are discussed. Furthermore, the ability of B. subtilis biofilms and spores to fabricate functional living materials with self-regenerating, self-regulating and environmentally responsive characteristics has been summarized. This review aims to resume advances in biological engineering of B. subtilis biofilms and spores and their applications.

Abstract
Phytases are important industrial enzymes widely used as feed additives to hydrolyze phytate and release inorganic phosphate. In this study, a phytase gene PhyBL isolated from Bacillus licheniformis WHU was cloned and expressed in Escherichia coli. PhyBL showed the highest activity at pH 7.0 and retained more than 40 % of its activity at a wide temperature range from 35 to 65 °C. Ca2+ significantly affected the stability and activity of the enzyme. We further improved the stability of PhyBL through extensively disulfide engineering. After constructing and screening a series of variants, an enhanced stable G197C/A358C variant was obtained. The G197C/A358C variant had a half-life at 60℃ roughly 3.8-fold longer than the wild type. In addition, the G197C/A358C variant also showed enhanced proteolytic resistance to pepsin and trypsin. The potential mechanism underlying these improvements was investigated by molecular dynamics analysis. Our results suggest that the G197C/A358C variant may have potential application as an additive enzyme in aquaculture feed.

Abstract
The bacterium Bacillus subtilis has long been an important subject for basic studies. However, this organism has also had industrial applications due to its easy genetic manipulation, favorable culturing characteristics for large-scale fermentation, superior capacity for protein secretion, and generally recognized as safe (GRAS) status. In addition, as the metabolically dormant form of B. subtilis, its spores have attracted great interest due to their extreme resistance to many environmental stresses, which makes spores a novel platform for a variety of applications. In this review, we summarize both conventional and emerging applications of B. subtilis spores, with a focus on how their unique characteristics have led to innovative applications in many areas of technology, including generation of stable and recyclable enzymes, synthetic biology, drug delivery, and material sciences. Ultimately, this review hopes to inspire the scientific community to leverage interdisciplinary approaches using spores to address global concerns about food shortages, environmental protection, and health care.

Abstract
Bacillus subtilis is a widely distributed aerobic Gram-positive species of bacteria. As a tool in the lab, it has the advantages of nonpathogenicity and limited likelihood of becoming drug resistant. It is a probiotic strain that can be directly used in humans and animals. It can be induced to produce spores under nutrient deficiency or other adverse conditions. B. subtilis spores have unique physical, chemical, and biochemical characteristics. Expression of heterologous antigens or proteins on the surface of B. subtilis spores has been successfully performed for over a decade. As an update and supplement to previously published research, this paper reviews the latest research on spore surface display technology using B. subtilis. We have mainly focused on the regulation of spore coat protein expression, display and application of exogenous proteins, and identification of developing research areas of spore surface display technology.
