Synthetic Biology of Genetic Microalgae

Synthetic Biology of Genetic Microalgae

Introduction

Microalgae have complex photosynthetic systems that capture solar energy and CO2. In addition, they grow faster than plants and have a relatively simple genetic background for genetic manipulation, making them relatively easy to manipulate. Therefore, they are becoming increasingly attractive for producing renewable biofuels and chemicals. As an emerging discipline that approaches biotechnology from a rational design approach, synthetic biology aims to redesign existing biological systems or create artificial life. In recent years, synthetic biology research has focused on model species such as Escherichia coli and yeast. However, following the completion and publication of over 40 cyanobacterial genome sequences and over 60 algal genome sequences, research efforts in synthetic biology approaches are increasingly modifying microalgae for various biotechnological applications.

Various synthetic biology approaches can be implemented in microalgae to improve biomass or metabolite productivity.Fig 1. Various synthetic biology approaches can be implemented in microalgae to improve biomass or metabolite productivity. (Naduthodi M I S, et al., 2021)

Customized Solutions

Basic theoretical and applied research on green biomanufacturing based on synthetic biology of microalgae is of great relevance to solve the environmental, resource, energy, and food problems faced by human beings and to achieve sustainable development of society. Our skilled scientists use synthetic biology tools to improve the yield of microalgae biofuels and other compounds. Lifeasible provides our clients with professional synthetic biology services for genetic microalgae to strengthen the following properties of microalgae:

(1) Improving photosynthetic efficiency through metabolic engineering to increase algal biomass productivity, oil production, and carbon sequestration rates.

(2) Conversion of carbon fluxes into valuable products.

(3) Develop input-ready microalgal cells to reduce production costs at scale.

Our goal is to modify fast-growing microalgae strains based on reliable genome editing tools to exploit their improved photosynthesis to produces interesting commodities. Our featured platforms are:

  • Resources such as genome sequences, selection markers, plasmid vectors, various promoters, and genetic editing tools.
  • A new BioBrick collection and characterization system.
  • Microalgal models that can be used to reverse genetic and synthetic biology perturbations, such as Chlamydomonas reinhardtii, Microcystis aeruginosa, Fucus triangularis, etc.
  • Metabolic network modeling at the genomic scale of microalgae for predicting new targets to improve product yields and new pathways.
