Overview Service Process Examples and Solutions Case Study Frequently Asked Questions


Penicillium species, including Penicillium chrysogenum and Penicillium roqueforti, are widely used in biotechnology for their ability to produce antibiotics, enzymes, and secondary metabolites. Our metabolic engineering services leverage advanced genetic engineering techniques, such as CRISPR/Cas9, homologous recombination, and synthetic biology approaches, to optimize the metabolic pathways of Penicillium for improved production of target compounds.

Service Process

The process of Penicillium metabolic engineering involves several critical and interrelated steps:

  1. Project Consultation: Collaborating with researchers to define specific metabolic engineering goals, including target compounds, desired metabolic modifications, and intended applications.
  2. Pathway Analysis and Design: Analyzing existing metabolic pathways and designing modifications to optimize the production of target compounds. This includes pathway reconstruction and flux balance analysis.
  3. Vector Design and Construction: Designing and constructing expression vectors or CRISPR/Cas9 systems tailored to the specific genetic modifications needed for the metabolic pathway.
  4. Fungal Transformation: Introducing the genetic material into Penicillium cells using techniques such as protoplast transformation, Agrobacterium-mediated transformation, or electroporation.
  5. Selection and Screening: Selecting successfully transformed cells using selectable markers and screening for desired metabolic modifications using assays such as HPLC, GC-MS, and enzymatic assays.
  6. Strain Optimization: Optimizing the engineered strains through iterative rounds of modification and selection to enhance the production of target compounds. This may include optimizing growth conditions and media composition.
  7. Characterization and Validation: Characterizing the engineered strains to confirm the presence and functionality of the metabolic modifications. This includes growth assays, metabolic profiling, and functional assays.
  8. Scale-Up and Production: Scaling up the engineered strains for large-scale production and further applications in research or industry.
  9. Reporting and Consultation: Providing a detailed report of the findings and offering further consultation to interpret the results and plan subsequent research steps.

Case Study

Penicillium chrysogenum was successfully engineered to produce a novel carbamoylated cephalosporin that can be used as a synthon for semi-synthetic cephalosporins. To this end, genes for Acremonium chrysogenum expandase/hydroxylase and Streptomyces clavuligerus carbamoyltransferase were expressed in a penicillinG high-producing strain of P. chrysogenum. Growth of the engineered strain in the presence of adipic acid resulted in production of adipoyl-7-amino-3-carbamoyloxymethyl3-cephem-4-carboxylic acid (ad7-ACCCA) and of several adipoylated pathway intermediates. A combinatorial chemostat-based transcriptome study, in which the ad7-ACCCA-producing strain and a strain lacking key genes in b-lactam synthesis were grown in the presence and absence of adipic acid, enabled the dissection of transcriptional responses to adipic acid per se and to ad7-ACCCA production. Transcriptome analysis revealed that adipate catabolism in P. chrysogenum occurs via b-oxidation and enabled the identification of putative genes for enzymes involved in mitochondrial and peroxisomal b-oxidation pathways. Several of the genes that showed a specifically altered transcript level in ad7- ACCCA-producing cultures were previously implicated in oxidative stress responses
