CD Biosynsis offers a premier, integrated platform for Phaeodactylum tricornutum Genome Editing and Metabolic Engineering Solutions, specifically designed to harness the industrial potential of this model pennate diatom. Recognized for its rapid growth, high lipid accumulation capacity, and significant role in marine biotechnology, Phaeodactylum tricornutum serves as an ideal eukaryotic chassis for the production of omega-3 fatty acids (EPA), high-value pigments like fucoxanthin, and biofuels. Our solutions provide the genetic precision required to navigate the diatom's complex evolutionary architecture, including its diploid genome and its unique four-membrane chloroplast system.
Our expert team delivers end-to-end support for algal engineering, moving beyond traditional random mutagenesis toward rational, data-driven design. We utilize cutting-edge CRISPR-based tools—including DNA-free RNP delivery and replicative episomes—to achieve stable, biallelic modifications that ensure phenotypic consistency. By integrating multi-omics analysis with predictive metabolic modeling, we empower researchers to redirect carbon flux with unprecedented accuracy. Whether you are conducting fundamental research on carbon concentrating mechanisms (CCM) or developing high-titer production strains for commercial photobioreactors, our platform provides the stability, reliability, and analytical depth needed for success in marine synthetic biology.
Get a QuoteOptimizing Phaeodactylum tricornutum involves managing the intricate coordination between the nucleus and its complex organelles. Our solutions utilize high-fidelity genome editing to bypass the historical limitations of diatom genetic manipulation, such as low homologous recombination rates and transgene silencing. We prioritize the development of "clean" chassis strains that maintain optimal photosynthetic efficiency while performing specialized metabolic functions.
Our metabolic engineering strategy focuses on the quantitative redistribution of energy and carbon resources. By applying Flux Balance Analysis (FBA) to the diatom's metabolic network, we identify competitive pathways—such as those involved in chrysolaminarin storage—that can be disrupted to maximize the synthesis of triacylglycerols (TAGs) or specific carotenoids. This systems-level approach ensures that the engineered strains are not only productive but also resilient under the variable light and nutrient conditions of large-scale marine cultivation environments.
Optimized nuclease platforms (Cas9/Cas12a) tailored for the specific codon bias and regulatory signals of the diatom nucleus.
Permanent biallelic disruption of target genes to eliminate metabolic bottlenecks or study functional marine genomics.
Site-specific integration of metabolic cassettes or reporters into validated genomic safe harbors via HDR-mediated repair.
Tunable, non-lethal gene knockdown for studying essential regulatory nodes and balancing competitive metabolic fluxes.
Precise single-nucleotide substitutions (C>T or A>G) for "scarless" protein engineering and herbicide resistance modeling.
Coordinated multi-gene engineering to maximize the titer and rate of target molecules like EPA and fucoxanthin.
Simultaneous disruption of redundant gene families using poly-cistronic gRNA arrays and specialized processing tools.
High-throughput screening and monoclonal isolation of diatom strains optimized for industrial photobioreactor performance.
Quantitative phenotyping integrated with genome-scale metabolic modeling (GEM) for predictive strain design.

Technical insights for your Phaeodactylum engineering project.
Contact Us1. How do you handle the diploid nature of Phaeodactylum tricornutum during editing?
We utilize high-efficiency CRISPR-Cas systems designed to induce bi-allelic modifications. We confirm success via targeted NGS or TIDE analysis to ensure no wild-type alleles remain in the monoclonal line.
2. Can you perform site-specific knock-in for multi-gene metabolic pathways?
Yes, we can integrate multi-gene cassettes into validated genomic safe harbors via HDR-mediated repair, ensuring stable and coordinated expression of complex pathways like EPA biosynthesis.
3. What are the advantages of using episomal vectors in diatoms?
Episomal vectors replicate independently of the chromosome. They allow for stable tool expression without random integration and can be "cured" or removed from the cell after editing is complete, resulting in scarless modification.
4. How do you address the robust gene silencing in this species?
We employ DNA-free RNP delivery or use vectors featuring native regulatory elements and optimized codon bias to ensure high and sustained expression levels that bypass host silencing mechanisms.
5. Is it possible to target the chloroplast genome specifically?
Yes, we offer specialized chloroplast engineering protocols using biolistic transformation to modify the photosynthetic machinery within the plastid genome.
6. Do you provide help with identifying metabolic bottlenecks?
Absolutely. Our modeling services utilize Flux Balance Analysis (FBA) and 13C-flux analysis to quantitatively identify nodes that limit the production of target bioproducts.
7. What is the typical turnaround time for a customized diatom strain?
Depending on the number of modifications and complexity, projects typically take between 16 to 22 weeks from initial modeling to the delivery of a verified monoclonal strain.
8. How is the genetic stability of the modified strains verified?
Strains are subjected to long-term stability testing (30-50 passages) and re-genotyped via NGS to ensure that the modifications and phenotypes remain constant over time.
Would you like to discuss specific genetic targets for enhancing the production of Omega-3 fatty acids or pigments in your Phaeodactylum tricornutum strains?
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.
