CD Biosynsis delivers comprehensive Corynebacterium glutamicum Strain Development and Screening Services, providing rational engineering and high-throughput assessment for industrial bioproduction. As a powerhouse for amino acid (e.g., L-lysine, L-glutamate) and fine chemical synthesis, optimizing C. glutamicum strains is critical for maximizing yield and streamlining fermentation. Our integrated platform combines advanced genetic engineering (including CRISPR-Cas9), automated high-throughput screening (HTS), and data-driven metabolic analysis. We offer end-to-end solutions, from constructing initial mutant libraries to identifying and validating the final, best-performing production strains, accelerating your path from concept to industrial scale-up.
Get a QuoteDeveloping high-titer production strains requires more than just genetic modification—it demands efficient identification of the best-performing clones. Traditional screening methods are slow and labor-intensive, often failing to capture subtle performance improvements. Our platform overcomes this by integrating cutting-edge engineering techniques with fully automated high-throughput screening and fermentation simulation. This synergy allows for the rapid testing of thousands of variants, ensuring that the final strains not only possess the desired genetic modification but also exhibit superior yield and robustness under industrial fermentation conditions, driving success in chemical and pharmaceutical biomanufacturing.

"The combination of rational engineering and their HTS platform led us to a lysine production strain with 30% higher yield than our previous best, all within a four-month timeline."
Dr. Lee, VP of R&D, Bioproduction Firm
"Their high-throughput screening successfully identified a single nucleotide change in a regulatory gene from a large mutant library, something manual screening would have missed entirely."
Mr. Alex Johnson, Bioengineering Lead, Specialty Chemicals
"We especially valued the final small-scale bioreactor validation; it gave us the confidence needed to immediately transition the strain into our pilot plant."
Dr. Maria Perez, Fermentation Director, Industrial Microbiology
What is the difference between Rational Engineering and Directed Evolution?
Rational Engineering (e.g., CRISPR-Cas9) uses known metabolic information to target specific genes; Directed Evolution (e.g., random mutagenesis) generates diversity to screen for unexpected improvements.
How high-throughput is your screening process?
Our automated HTS systems can screen tens of thousands of individual C. glutamicum clones per project cycle, drastically accelerating the identification of high-yield strains.
How do you ensure the strain performance is relevant to industrial scale-up?
We perform mandatory final validation in small-scale, tightly controlled bioreactors (Fermentation Mimicry) to test strain robustness and performance under simulated industrial conditions (pH, DO control).
Do you offer marker-free strains?
Yes. Any genetic modifications performed by our platform are designed to be marker-free, ensuring compliance and maximizing the genetic stability of the final production strain.
What kind of analysis is included with the final strain delivery?
The deliverables include the final strain, a detailed Certificate of Analysis (CoA), full genetic sequence confirmation of the modifications, and a summary of the phenotypic validation data (titer/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.
