Get a Customized Project QuoteOur CRISPR-Cas9 system utilizes customized single guide RNAs (sgRNAs) to direct the Cas9 nuclease to specific genomic loci within Bacillus subtilis. The subsequent double-strand break (DSB) is repaired via the host's native pathways, allowing for the precise insertion or deletion of DNA fragments using a homologous repair template. This method is vastly superior to traditional homologous recombination alone in terms of speed and efficiency, making complex multiplex editing feasible for large-scale pathway optimization projects.
KO Objective
Eliminate competing metabolic pathways or native protease genes (e.g., aprE, nprE) to enhance product yield or stability.
Strategy
Utilizing a repair template to ensure precise deletion without leaving a residual selection marker, facilitating subsequent editing rounds.
KI Objective
Insert large heterologous pathways, strong promoters, or reporter genes into specific, high-expression chromosomal loci.
Strategy
CRISPR-mediated DSB significantly boosts the efficiency of homologous recombination for reliable integration of up to 5kb fragments.
Mutation Type
Introduction of single amino acid substitutions, promoter strength tuning (SNPs), or codon usage optimization for enhanced gene function.
Validation
All point mutations are confirmed via high-resolution Sanger sequencing of the entire modified locus, guaranteeing single-base precision.
Unparalleled Efficiency
CRISPR-Cas9 increases editing rates 10-fold over traditional methods, dramatically shortening project timelines.

Still have questions about our precision editing platform?
Contact UsWhat types of B. subtilis edits can CRISPR-Cas9 achieve?
CRISPR-Cas9 enables highly precise gene knock-in (KI), gene knock-out (KO), single nucleotide polymorphisms (point mutations), and large fragment deletions in the B. subtilis genome.
Is the CRISPR-Cas9 editing in B. subtilis permanent and marker-less?
Yes. Our optimized system utilizes double-strand break repair mechanisms to integrate the changes directly into the chromosome, yielding stable, marker-less strains without residual antibiotic resistance genes.
How is off-target editing controlled in your B. subtilis CRISPR system?
We employ sophisticated sgRNA design algorithms and optimized vector expression systems to minimize potential off-target effects. All final strains are validated via whole-locus sequencing to confirm on-target specificity.
Can I request multiplex genome editing in B. subtilis?
Absolutely. Our platform supports the simultaneous targeting of multiple genes (multiplex editing) using customized sgRNA arrays, which is essential for complex metabolic pathway engineering and chassis optimization.
CRISPR-Cas9 technology represents a transformative advancement in gene editing techniques. The main function of the system is to precisely cut DNA sequences by combining guide RNA (gRNA) with the Cas9 protein. This technology became a mainstream genome editing tool quickly after its 2012 introduction because of its efficient, simple and low-cost nature.
The CRISPR gene editing system with its Cas9 version stands as a vital instrument for current biological research. CRISPR technology enables gene knockout (KO) through permanent gene expression blockage achieved by sequence disruption. Various scientific domains including disease modeling and drug screening employ this technology to study gene functions. CRISPR KO technology demonstrates high efficiency and precision but requires confirmation and verification post-implementation because unsatisfactory editing may produce off-target effects or incomplete gene knockouts which impact experimental result reliability. For precise and efficient Gene Editing Services - CD Biosynsis, Biosynsis offers comprehensive solutions tailored to your research needs.
The CRISPR-Cas9 knockout cell line was developed using CRISPR/Cas9 gene editing to allow scientists to remove genes accurately for research on gene function and disease models and pharmaceutical discovery. Genetic research considers this technology essential due to its high efficiency together with simple operation and broad usability.
