Overview Service Process Examples and Solutions Frequently Asked Questions


Bacillus subtilis is a gram-positive bacterium widely used in biotechnology due to its ability to secrete large quantities of proteins and its well-characterized genetics. Our metabolic engineering services leverage advanced genetic engineering techniques, such as CRISPR/Cas9, homologous recombination, and synthetic biology approaches, to optimize the metabolic pathways of Bacillus subtilis for improved production of target compounds.

Methods for Bacillus Subtilis Metabolic Engineering

Method Description Applicable Scenarios
Gene Knockout Deletion of specific genes to remove competing pathways or regulatory elements, redirecting metabolic fluxes towards the production of the desired compound. Suitable for increasing the yield of target products by eliminating pathways that divert resources, commonly used in enzyme production.
Gene Overexpression Insertion or amplification of genes to enhance the activity of enzymes in the target metabolic pathway. Ideal for boosting the production of rate-limiting steps, increasing overall pathway flux, often used in the production of biofuels and chemicals.
Promoter Engineering Modification of promoter sequences to optimize gene expression levels, ensuring balanced and efficient metabolic flux. Suitable for fine-tuning gene expression, improving product yield and reducing metabolic burden, often used in protein secretion.
CRISPR/Cas9 Genome Editing Utilization of CRISPR/Cas9 technology for precise and efficient genome editing, allowing targeted modifications such as gene knockouts or insertions. Ideal for rapid and accurate genetic modifications, commonly used in strain development and functional genomics studies.
Synthetic Pathway Construction Design and assembly of synthetic metabolic pathways to produce novel compounds or enhance existing production routes. Suitable for creating new biosynthetic capabilities, often used in the production of pharmaceuticals and specialty chemicals.
Adaptive Laboratory Evolution (ALE) Applying selective pressure to evolve Bacillus subtilis strains with enhanced production traits or stress resistance. Ideal for developing strains with improved performance under industrial fermentation conditions, such as high substrate concentrations or temperature.
Metabolic Flux Analysis (MFA) Quantitative assessment of metabolic pathways to identify bottlenecks and optimize the distribution of metabolic fluxes. Useful for guiding genetic engineering strategies and validating the effects of modifications, often used in optimizing production strains.
Systems Biology Approaches Integration of omics data (genomics, transcriptomics, proteomics, metabolomics) to comprehensively understand and engineer metabolic networks. Suitable for large-scale pathway optimization and identifying novel engineering targets, often used in advanced metabolic engineering projects.
Protein Engineering Directed evolution or rational design to improve the properties of enzymes involved in the target metabolic pathway. Ideal for enhancing enzyme activity, stability, or substrate specificity, improving overall pathway efficiency and product yield.
Plasmid-based Expression Systems Use of plasmids to introduce and express genes in Bacillus subtilis, providing a flexible approach for pathway engineering and optimization. Suitable for testing and optimizing metabolic pathways before chromosomal integration, often used in research and early-stage development.

Bacillus subtilis metabolic engineering leverages these methods to develop robust and efficient strains for industrial applications. The choice of method depends on the specific goals of the project, such as the desired product, production scale, and process conditions. These engineering strategies are essential for advancing biotechnological innovations and developing sustainable industrial processes.
