Lycopene Ester Bioproduction Engineering Service

Lycopene Ester is a highly stable, lipophilic derivative of Lycopene, offering enhanced bioavailability and color stability compared to free Lycopene. It is widely used in functional foods, supplements, and cosmetics. Production faces challenges: extraction from natural sources like tomatoes yields low extraction amount in tomatoes and results in complex mixtures. Furthermore, Lycopene itself has poor stability in chemical synthesis and processing, prone to degradation by light and heat. Biosynthesis in engineered yeast offers a sustainable, highly stable, and cost-effective source.

CD Biosynsis offers a synthetic biology service focused on the high-titer production of Lycopene Ester in Saccharomyces cerevisiae. Our core strategy involves modification of yeast carotenoid pathway . We engineer the upstream mevalonate (MVA) pathway to dramatically increase the supply of the precursor Farnesyl Diphosphate (FPP) , and then introduce the bacterial gene cluster for Lycopene synthesis (CrtE, CrtB, CrtI). Crucially, this is coupled with the heterologous expression of ester synthase —introducing a Lycopene Acyltransferase gene to efficiently convert the newly synthesized Lycopene into the highly stable Lycopene Ester (e.g., lycopene oleate or palmitate). This integrated approach aims to deliver a high-yield, specific, and intrinsically stable Lycopene Ester product.

Pain Points

Developing a competitive Lycopene Ester bioproduction route faces these key limitations:

• Low Extraction Amount in Tomatoes: Natural sources like tomatoes contain Lycopene and its esters in low concentrations , making large-scale extraction economically unviable and environmentally wasteful.
• Poor Stability in Chemical Synthesis: Free Lycopene is a long, highly conjugated molecule that is extremely sensitive to heat, oxygen, and light , rapidly degrading during conventional chemical handling and storage.
• Metabolic Bottlenecks: The upstream MVA pathway in yeast is tightly regulated, leading to insufficient supply of FPP (the Lycopene precursor), severely limiting flux.
• Esterification Deficiency: Yeast does not naturally possess the specific Acyltransferase necessary to convert free Lycopene (an alcohol) into the highly stable ester form.

A successful solution must overcome upstream supply limitations and implement the specific enzymatic step for esterification and stabilization.

Solutions

CD Biosynsis utilizes advanced synthetic biology to engineer S. cerevisiae for high-yield Lycopene Ester production:

Modification of Yeast Carotenoid Pathway

           

We overexpress key rate-limiting enzymes (HMG-CoA reductase) and downregulate competing pathways (ergosterol synthesis) to maximize the flux toward FPP and Lycopene.

Heterologous Expression of Ester Synthase

We introduce and optimize the expression of a Lycopene Acyltransferase from a suitable host (e.g., bacteria or fungi) to efficiently perform the final esterification step.

Lycopene Synthesis Gene Cluster Optimization

We co-express and optimize the balance of the CrtE, CrtB, and CrtI genes needed to convert FPP into the Lycopene backbone.

Lipid Metabolism and Storage Enhancement

We engineer the host to increase neutral lipid storage (lipid droplets) , which serve as an intracellular sink for the hydrophobic ester product, boosting accumulation.

This systematic approach is focused on maximizing the carbon flux toward the carotenoid pathway and adding the final stabilization step.

Advantages

Our Lycopene Ester engineering service is dedicated to pursuing the following production goals:

Enhanced Product Stability

Esterification significantly protects Lycopene from oxidation and degradation during formulation and storage.

High Specific Titer

Upstream pathway enhancement leads to high Lycopene Ester accumulation that far exceeds levels achievable in natural sources.

Sustainable Production Route

Fermentation utilizes renewable sugar feedstock instead of relying on inefficient agricultural extraction methods.

Simplified Extraction

The product's hydrophobic nature allows it to be stored efficiently in lipid droplets , facilitating simpler organic solvent extraction.

Increased Bioavailability

The ester form is highly lipophilic, which is crucial for efficient absorption in the human gut.

We provide a specialized metabolic engineering platform aimed at optimizing the yield and stability of Lycopene Ester compounds.

Process

Our Lycopene Ester strain engineering service follows a rigorous, multi-stage research workflow:

• MVA Pathway Enhancement: Overexpress the initial, rate-limiting enzymes of the MVA pathway to maximize FPP precursor supply.
• Carotenoid Cluster Integration: Integrate the heterologous Lycopene synthesis genes (CrtE, CrtB, CrtI) into the yeast genome for stable, balanced expression .
• Esterification Gene Introduction: Introduce and optimize the expression of the target Lycopene Acyltransferase to ensure efficient final product conversion .
• Fatty Acid Pool Tuning: Modify the host's fatty acid synthesis pathway to control the type of fatty acid available for esterification, dictating the final ester form (e.g., oleate, palmitate).
• Fermentation Performance Validation: Test the final engineered strain in fed-batch fermentation to assess Lycopene Ester titer, yield, and stability .
• Result Report Output: Compile a detailed Experimental Report including gene modification data, HPLC analysis of the ester profile, and fermentation metrics (yield, titer, and ester ratio) , supporting commercial scale-up.

Technical communication is maintained throughout the process, focusing on timely feedback regarding yield and specific ester structure.
