Get a QuoteAchieving high efficiency in C. glutamicum bioprocesses requires moving beyond trial-and-error engineering. Our services are designed to quantitatively measure the impact of genetic modifications and fermentation conditions. Traditional methods often provide only end-point data, limiting the ability to troubleshoot bottlenecks. Our combined assay and modeling approach provides dynamic, holistic data, utilizing tools like 13C Metabolic Flux Analysis (13C-MFA) to precisely map carbon flow and identify rate-limiting steps. By integrating these experimental data into predictive genome-scale metabolic models (GEMs), we offer rational guidance for optimal strain design and medium component tuning, ensuring a targeted and successful engineering strategy.

"The 13C-MFA data was instrumental; it proved that the bottleneck wasn't the final enzyme, but an unexpected upstream regulation, allowing us to redesign our strain effectively."
Dr. Elena Rodriguez, Head of Metabolic Research, Biotechnology Firm
"The Genome-Scale Model provided an in silico prediction for a $3 \text{X}$ knockout strategy that successfully increased our target chemical production by $15\%$. Highly accurate guidance."
Mr. Kenji Tanaka, Lead Computational Biologist, Industrial Engineering Group
"The integration of metabolomics and proteomics gave us a complete picture of the stress response in our high-titer strain, helping us stabilize the bioprocess."

What is 13C Metabolic Flux Analysis (13C-MFA) and why is it important?
13C-MFA is an analytical technique using stable isotopes to precisely map the flow of carbon (flux) through intracellular pathways. It is essential because it identifies the true rate-limiting steps (bottlenecks) which cannot be found by simply measuring metabolite levels.
How does the Genome-Scale Metabolic Model (GEM) guide engineering?
GEMs allow for in silico (computational) prediction of the outcome of genetic perturbations (e.g., gene deletion, overexpression) on the production of a target compound, providing a rational basis for strain design (e.g., using FBA or MOMA algorithms).
Can you model non-steady state (dynamic) conditions?
Yes. In addition to steady-state flux analysis, we offer kinetic modeling services for specific pathways, which simulates dynamic changes over time and is crucial for optimizing time-dependent fermentation processes.
What data is required to start a modeling project?
A basic modeling project requires only the host genome sequence and defined medium conditions. However, model accuracy is maximized when experimental data, such as quantitative growth rates, exchange rates, and especially 13C-MFA derived fluxes, are provided or generated by our services.
What are the final deliverables for a combined assay and modeling service?
The deliverables include: a comprehensive report with validated flux maps, the custom-built GEM/kinetic model files, and concrete, ranked recommendations for genetic targets or bioprocess parameters to maximize yield.
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.
