[PMID: 36838875 PMCID: PMC9960984 DOI: 10.3390/molecules28041888] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 02/08/2023] [Accepted: 02/14/2023] [Indexed: 02/18/2023] Open
Abstract
3-Hydroxypropionic acid (3-HP) is a platform chemical with a wide range of existing and potential applications, including the production of poly(3-hydroxypropionate) (P-3HP), a biodegradable plastic. The microbial synthesis of 3-HP has attracted significant attention in recent years due to its green and sustainable properties. In this paper, we provide an overview of the microbial synthesis of 3-HP from four major aspects, including the main 3-HP biosynthesis pathways and chassis strains used for the construction of microbial cell factories, the major carbon sources used for 3-HP production, and fermentation processes. Recent advances in the biosynthesis of 3-HP and related metabolic engineering strategies are also summarized. Finally, this article provides insights into the future direction of 3-HP biosynthesis.

[PMID: 32898717 DOI: 10.1016/j.ymben.2020.09.001] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 08/19/2020] [Accepted: 09/01/2020] [Indexed: 10/23/2022]
Abstract
1,3-Propanediol (1,3-PDO) is an important platform chemical which has a wide application in food, cosmetics, pharmaceutical and textile industries. Its biological production using recombinant Escherichia coli with glucose as carbon source has been commercialized by DuPont, but E. coli cannot synthesize coenzyme B12 which is an essential and expensive cofactor of glycerol dehydratase, a core enzyme in 1,3-PDO biosynthesis. This study aims to develop a more economical microbial cell factory using Klebsiella pneumoniae J2B which can naturally synthesize coenzyme B12. To this end, the heterologous pathway for the production of glycerol from dihydroxyacetone-3-phosphate (DHAP), a glycolytic intermediate, was introduced to J2B and, afterwards, the strain was extensively modified for carbon and energy metabolisms including: (i) removal of carbon catabolite repression, (ii) blockage of glycerol export across the cell membrane, (iii) improvement of NADH regeneration/availability, (iv) modification of TCA cycle and electron transport chain, (v) overexpression of 1,3-PDO module enzyme, and (vi) overexpression of glucose transporter. A total of 33 genes were modified and/or overexpressed, and one resulting strain could produce 814 mM (62 g/L) of 1,3-PDO with the yield of 1.27 mol/mol glucose in fed-batch bioreactor culture with a limited supplementation of coenzyme B12 at 4 μM, which is ~10 fold less than that employed by DuPont. This study highlights the importance of balanced use of glucose in the production of carbon backbone of the target chemical (1,3-PDO) and regeneration of reducing power (NADH). This study also suggests that K. pneumoniae J2B is a promising host for the production of 1,3-PDO from glucose.

Small Current but Highly Productive Synthesis of 1,3-Propanediol from Glycerol by an Electrode-Driven Metabolic Shift in Klebsiella pneumoniae L17. CHEMSUSCHEM 2020; 13:564-573.

Abstract
Electrofermentation actively regulates the bacterial redox state, which is essential for bioconversion and has been highlighted as an effective method for further improvements of the productivity of either reduced or oxidized platform chemicals. 1,3-Propanediol (1,3-PDO) is an industrial value-added chemical that can be produced from glycerol fermentation. The bioconversion of 1,3-PDO from glycerol requires additional reducing energy under anoxic conditions. The cathode-based conversion of glycerol to 1,3-PDO with various electron shuttles (2-hydroxy-1,4-naphthoquinone, neutral red, and hydroquinone) using Klebsiella pneumoniae L17 was investigated. The externally poised potential of -0.9 V vs. Ag/AgCl to the cathode increased 1,3-PDO (35.5±3.1 mm) production if 100 μm neutral red was used compared with non-bioelectrochemical system fermentation (23.7±2.4 mm). Stoichiometric metabolic flux and transcriptional analysis indicated a shift in the carbon flux toward the glycerol reductive pathway. The homologous overexpression of glycerol dehydratase (DhaB) and 1,3-PDO oxidoreductase (DhaT) enzymes synergistically enhanced 1,3-PDO conversion (39.3±0.8 mm) under cathode-driven fermentation. Interestingly, a small current uptake (0.23 mmol of electrons) caused significant metabolic flux changes with a concomitant increase in 1,3-PDO production. This suggests that both an increase in 1,3-PDO production and regulation of the cellular metabolic pathway are feasible by electrode-driven control in cathodic electrofermentation.

Abstract
3-hydroxypropanoic acid (3-HP) is a valuable platform chemical with a high demand in the global market. 3-HP can be produced from various renewable resources. It is used as a precursor in industrial production of a number of chemicals, such as acrylic acid and its many derivatives. In its polymerized form, 3-HP can be used in bioplastic production. Several microbes naturally possess the biosynthetic pathways for production of 3-HP, and a number of these pathways have been introduced in some widely used cell factories, such as Escherichia coli and Saccharomyces cerevisiae. Latest advances in the field of metabolic engineering and synthetic biology have led to more efficient methods for bio-production of 3-HP. These include new approaches for introducing heterologous pathways, precise control of gene expression, rational enzyme engineering, redirecting the carbon flux based on in silico predictions using genome scale metabolic models, as well as optimizing fermentation conditions. Despite the fact that the production of 3-HP has been extensively explored in established industrially relevant cell factories, the current production processes have not yet reached the levels required for industrial exploitation. In this review, we explore the state of the art in 3-HP bio-production, comparing the yields and titers achieved in different microbial cell factories and we discuss possible methodologies that could make the final step toward industrially relevant cell factories.

Abstract
The production of 1,3-propanediol (1,3-PDO) from glucose was investigated using Klebsiella pneumoniae J2B, which converts glycerol to 1,3-PDO and synthesize an essential coenzyme B12. In order to connect the glycolytic pathway with the pathway of 1,3-PDO synthesis from glycerol, i.e., to directly produce diol from glucose, glycerol-3-phosphate dehydrogenase and glycerol-3-phosphate phosphatase from Saccharomyces cerevisiae were overexpressed. Additionally, the effect of expression levels and the use of isoforms of these two enzymes on glycerol and 1,3-PDO production were studied. Furthermore, to prevent loss of produced glycerol, the glycerol oxidation pathways were disrupted. Finally, the conversion rate of glycerol to 1,3-PDO was increased via homologous overexpression of glycerol dehydratase and 1,3-PDO oxidoreductase. The resultant strain successfully produced 1,3-PDO from glucose at a yield of 0.27mol/mol along with glycerol at 0.52mol/mol. Improvement of the engineered K. pneumoniae J2B to further increase conversion of glycerol to 1,3-PDO is discussed.

BIORESOURCE TECHNOLOGY 2017; 244:1096-1103.

Abstract
Production of 3-hydroxypropionic acid (3-HP) or 1,3-propanediol (1,3-PDO) production from glycerol is challenging due to the problems associated with cofactor regeneration, coenzyme B12 synthesis, and the instability of pathway enzymes. To address these complications, simultaneous production of 3-HP and 1,3-PDO, instead of individual production of each compound, was attempted. With over-expression of an aldehyde dehydrogenase, recombinant Klebsiella pneumoniae could co-produce 3-HP and 1,3-PDO successfully. However, the production level was unsatisfactory due to excessive accumulation of many by-products, especially acetate. To reduce acetate production, we attempted; (i) reduction of glycerol assimilation through the glycolytic pathway, (ii) increase of glycerol flow towards co-production, and (iii) variation of aeration rate. These efforts were partially beneficial in reducing acetate and improving co-production: 21g/L of 1,3-PDO and 43g/L of 3-HP were obtained. Excessive acetate (>150mM) was still produced at the end of bioreactor runs, and limited co-production efficiency.
