CD Biosynsis offers specialized Chlamydomonas reinhardtii Strain Development and Screening Services, providing a high-throughput platform for the creation and isolation of optimized algal variants. Chlamydomonas reinhardtii serves as a vital chassis for photosynthetic research and industrial biotechnology, but establishing stable, high-performing strains requires navigating complex nuclear and chloroplast genomes. Our service integrates precision genome editing with automated screening technologies to identify clones with superior growth kinetics, lipid productivity, or recombinant protein yields. We facilitate the transition from laboratory models to industrial-ready strains, ensuring genetic stability and phenotypic consistency throughout the development process.
The development of custom Chlamydomonas strains is essential for researchers looking to maximize metabolic flux or study specific physiological traits under controlled conditions. Traditional methods of strain selection are often slow and lack the precision needed for modern synthetic biology. By combining DNA-free CRISPR-Cas9 engineering with automated single-cell isolation, we drastically shorten the development timeline. Our platform allows for the simultaneous evaluation of thousands of monoclonal candidates, ensuring that only the most robust and productive strains are selected for scale-up. Whether your goal is biofuel optimization, carbon sequestration enhancement, or the production of complex biopharmaceuticals, our tailored solutions provide the necessary expertise to build a high-performance algal strain.
Get a QuoteEstablishing a successful Chlamydomonas strain involves more than just genetic modification; it requires rigorous screening to ensure that the modifications translate into the desired phenotypic performance. Our service addresses the common problem of "phenotypic drift" by employing strict monoclonal isolation protocols and long-term stability trials. We utilize specialized photobioreactor systems to screen clones under various light intensities, CO2 concentrations, and nutrient regimes, identifying those that maintain high productivity in industrial-like environments.
Our metabolic engineering team uses these screening data to further refine the strain. By correlating genetic edits with phenotypic outputs, we can perform secondary rounds of engineering—such as knocking out inhibitory proteases or optimizing the secretion pathway—to achieve a "chassis" that is perfectly tuned for your specific application. This data-driven approach ensures a high success rate and provides deep insights into the factors governing algal productivity and resilience.

1. How do you ensure the stability of the engineered traits?
Stability is verified through continuous subculturing (at least 30 passages) followed by re-genotyping and re-phenotyping to ensure no genetic reversion or silencing has occurred.
2. Can you develop strains from wild-type or industrial algal isolates?
Yes, while we work with standard model strains like cc-124 or cc-125, we can also optimize transformation and screening protocols for custom industrial isolates.
3. What is the advantage of automated single-cell screening?
Automation allows us to sample the rare high-performers within a large edited population that would be missed by traditional manual screening methods.
4. Do you provide strains for both adherent and suspension growth?
Yes, we can screen and optimize strains for various growth modes, including high-density suspension in bioreactors or specialized biofilm cultivation systems.
5. What is the typical lead time for custom strain development?
A standard project, including engineering, high-throughput screening, and stability verification, typically takes 18 to 24 weeks.
6. Is codon optimization included in the service?
Absolutely. We provide comprehensive codon optimization based on the 64 percent GC bias of Chlamydomonas to ensure high expression of all transgenes.
7. Can you develop "homoplasic" chloroplast strains?
Yes. For chloroplast engineering, we perform multiple rounds of selective plating to ensure that all copies of the chloroplast genome contain the desired edit.

The report includes NGS genotyping results, growth curve data, metabolic analysis (lipid/protein/pigment), and proof of monoclonal isolation.
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.
