Overview Service Process Examples and Solutions Frequently Asked Questions


Bacterial metabolic engineering involves the genetic modification of bacterial strains to optimize their metabolic pathways for the production of target compounds. By introducing, deleting, or modifying specific genes, researchers can redirect metabolic fluxes to increase the yield and efficiency of desired products. Our services leverage advanced genetic engineering techniques, such as CRISPR/Cas9, homologous recombination, and synthetic biology approaches, to deliver high-quality engineered bacterial strains.

Methods for Bacterial Metabolic Engineering

Method Description Applicable Scenarios
Gene Knockout Deletion of specific genes to redirect metabolic fluxes towards the production of desired compounds. Suitable for eliminating pathways that compete with the desired product pathway, increasing yield and efficiency.
Gene Overexpression Introduction or amplification of genes to enhance the production of enzymes involved in the desired metabolic pathway. Ideal for increasing the activity of rate-limiting steps in a pathway, boosting the overall production of the target compound.
Pathway Optimization Fine-tuning of metabolic pathways through the modification of regulatory elements, such as promoters and ribosome binding sites. Suitable for balancing metabolic fluxes and reducing the accumulation of toxic intermediates, improving overall pathway efficiency.
Synthetic Biology Tools Utilization of synthetic biology techniques to design and construct novel metabolic pathways or circuits within bacteria. Ideal for creating entirely new biosynthetic routes or enhancing existing pathways, often used in the production of complex molecules.
CRISPR/Cas9 Genome Editing Precise editing of bacterial genomes using CRISPR/Cas9 technology to introduce, delete, or modify specific genes. Suitable for targeted modifications and rapid prototyping of engineered strains, commonly used in metabolic engineering and synthetic biology.
Adaptive Laboratory Evolution (ALE) Application of selective pressure to evolve bacterial strains with enhanced production capabilities or resistance to specific conditions. Ideal for improving strain performance under industrial conditions, such as high substrate concentrations or extreme pH.
Metabolic Flux Analysis (MFA) Quantitative analysis of metabolic fluxes within the cell to identify bottlenecks and optimize pathway performance. Useful for guiding metabolic engineering efforts and validating the effects of genetic modifications, often used in strain optimization.
Systems Biology Approaches Integration of omics data (genomics, transcriptomics, proteomics, metabolomics) to understand and engineer complex metabolic networks. Suitable for comprehensive pathway optimization and identifying novel engineering targets, often used in advanced metabolic engineering projects.
Directed Evolution Iterative cycles of mutagenesis and selection to evolve enzymes with improved activity, stability, or substrate specificity. Ideal for optimizing enzyme performance within metabolic pathways, enhancing overall production efficiency.
Plasmid-based Expression Systems Use of plasmids to introduce and express genes in bacteria, allowing for flexible and modular pathway engineering. Suitable for preliminary testing and optimization of metabolic pathways before chromosomal integration, commonly used in research and development.

Bacterial metabolic engineering services leverage these methods to develop strains that can efficiently produce a wide range of valuable compounds. The choice of method depends on the specific goals of the project, such as the type of compound being produced, the desired yield, and the characteristics of the bacterial host. These services are crucial for advancing biotechnology and developing sustainable industrial processes.
