Abstract
Metabolic engineering has witnessed remarkable advancements, enabling successful large-scale, cost-effective and efficient production of numerous compounds. However, the predominant expression of heterologous genes in the cytoplasm poses limitations, such as low substrate concentration, metabolic competition and product toxicity. To overcome these challenges, compartmentalized metabolic engineering allows the spatial separation of metabolic pathways for the efficient and precise production of target compounds. Compartmentalized metabolic engineering and its common strategies are comprehensively described in this study, where various membranous compartments and membraneless compartments have been used for compartmentalization and constructive progress has been made. Additionally, the challenges and future directions are discussed in depth. This review is dedicated to providing compartmentalized, precise and efficient methods for metabolic production, and provides valuable guidance for further development in the field of metabolic engineering.

Increased CO 2 fixation enables high carbon-yield production of 3-hydroxypropionic acid in yeast. Nat Commun 2024; 15:1591. [PMID: 38383540 PMCID: PMC10881976 DOI: 10.1038/s41467-024-45557-9] [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: 08/31/2023] [Accepted: 01/28/2024] [Indexed: 02/23/2024] Open
Abstract
CO2 fixation plays a key role to make biobased production cost competitive. Here, we use 3-hydroxypropionic acid (3-HP) to showcase how CO2 fixation enables approaching theoretical-yield production. Using genome-scale metabolic models to calculate the production envelope, we demonstrate that the provision of bicarbonate, formed from CO2, restricts previous attempts for high yield production of 3-HP. We thus develop multiple strategies for bicarbonate uptake, including the identification of Sul1 as a potential bicarbonate transporter, domain swapping of malonyl-CoA reductase, identification of Esbp6 as a potential 3-HP exporter, and deletion of Uga1 to prevent 3-HP degradation. The combined rational engineering increases 3-HP production from 0.14 g/L to 11.25 g/L in shake flask using 20 g/L glucose, approaching the maximum theoretical yield with concurrent biomass formation. The engineered yeast forms the basis for commercialization of bio-acrylic acid, while our CO2 fixation strategies pave the way for CO2 being used as the sole carbon source.

Glycerol as substrate and NADP +-dependent glyceraldehyde-3-phosphate dehydrogenase enable higher production of 3-hydroxypropionic acid through the β-alanine pathway in E. coli. BIORESOURCE TECHNOLOGY 2024; 393:130142.

Abstract
Microbial engineering is a promising way to produce3-HP using biorenewable substrates such as glycerol. However, theglycerol pathway to obtain 3-HPrequires vitamin B-12, which hinders its economic viability. The present work showed that 3-HP can be efficiently produced from glycerol through the β-alanine pathway. To develop a cell factory for this purpose, glycerol was evaluated as a substrate and showed more than two-fold improved 3-HP production compared to glucose. Next, the reducing power was modulated by overexpression of an NADP+ -dependent glyceraldehyde-3-phosphate dehydrogenase coupled with CRISPR-based repression of the endogenous gapA gene, resulting in a 91 % increase in 3-HP titer. Finally, the toxicity of 3-HP accumulation was addressed by overexpressing a putative exporter (YohJK). Fed-batch cultivation of the final strain yielded 72.2 g/L of 3-HP and a productivity of 1.64 g/L/h, which are the best results for the β-alanine pathway and are similar to those found for other pathways.

Abstract
Microbial cell factories offer an eco-friendly alternative for transforming raw materials into commercially valuable products because of their reduced carbon impact compared to conventional industrial procedures. These systems often depend on lignocellulosic feedstocks, mainly pentose and hexose sugars. One major hurdle when utilizing these sugars, especially glucose, is balancing carbon allocation to satisfy energy, cofactor, and other essential component needs for cellular proliferation while maintaining a robust yield. Nearly half or more of this carbon is inevitably lost as CO2 during the biosynthesis of regular metabolic necessities. This loss lowers the production yield and compromises the benefit of reducing greenhouse gas emissions-a fundamental advantage of biomanufacturing. This review paper posits the perspectives of using CO2 from the atmosphere, industrial wastes, or the exhausted gases generated in microbial fermentation as a feedstock for biomanufacturing. Achieving the carbon-neutral or -negative goals is addressed under two main strategies. The one-step strategy uses novel metabolic pathway design and engineering approaches to directly fix the CO2 toward the synthesis of the desired products. Due to the limitation of the yield and efficiency in one-step fixation, the two-step strategy aims to integrate firstly the electrochemical conversion of the exhausted CO2 into C1/C2 products such as formate, methanol, acetate, and ethanol, and a second fermentation process to utilize the CO2-derived C1/C2 chemicals or co-utilize C5/C6 sugars and C1/C2 chemicals for product formation. The potential and challenges of using CO2 as a feedstock for future biomanufacturing of fuels and chemicals are also discussed.

Abstract
Microbial 3-hydroxypropionic acid (3-HP) production can potentially replace petroleum-based production methods for acrylic acid. Here, we constructed a yeast strain that expressed enzymes related to 3-HP biosynthesis within the mitochondria. This approach aimed to enhance the 3-HP production by utilizing the mitochondrial acetyl-CoA, an important intermediate for synthesizing 3-HP. The strain that expressed 3-HP-producing enzymes in the mitochondria (YPH-mtA3HP) showed improved production of 3-HP compared to that shown by the strain expressing 3-HP-producing enzymes in the cytosol (YPH-cyA3HP). Additionally, cMCR was overexpressed, which regulates a rate-limiting reaction in synthesizing 3-HP. In this study, we aimed to further enhance 3-HP production by expressing multiple copies of cMCR in the mitochondria using the δ-integration strategy to optimize the expression level of cMCR (YPH-mtA3HPx*). The results of flask-scale cultivation showed that 3-HP production by cMCR δ-integration was significantly higher, exhibiting a yield of 160 mg/L in YPH-mtA3HP6* strain and 257 mg/L in YPH-mtA3HP22* strain. Notably, YPH-mtA3HP22*, exhibited the highest 3-HP titer, which was 3.2-fold higher than that of YPH-cyA3HP. Our results demonstrated the potential of utilizing the mitochondrial compartment within S. cerevisiae for enhancing 3-HP production.
