Pyruvic Acid Bioproduction Engineering Service

Pyruvic Acid (Pyruvate) is a foundational organic acid in central metabolism, serving as a critical energy intermediate and a precursor for numerous high-value chemicals, including amino acids, pharmaceuticals, and biodegradable polymers. Commercial biological production is hindered by microbial toxicity issues and the rapid diversion of Pyruvate into unwanted byproducts (like lactate and acetate).

We offer specialized Genetic Engineering and Metabolic Engineering services to optimize Pyruvic Acid biosynthesis. Our core strategy involves genetically eliminating all major Pyruvate-consuming pathways (PFL, LDH, etc.) to ensure high yield. Crucially, we enhance precursor supply and reduce product toxicity by overexpressing key enzymes like Pyruvate Carboxylase (PPC) and engineering efficient membrane transporters for rapid Pyruvate secretion from the cell.

Pain Points

The microbial production of Pyruvic Acid faces several key challenges:

• Pyruvate Toxicity: High intracellular concentrations of Pyruvate are toxic to microbial hosts, inhibiting cell growth and severely limiting the final achievable fermentation titer.
• Byproduct Formation: Pyruvate is a central metabolic intermediate. Native pathways quickly convert it into unwanted and low-value byproducts such as Lactic Acid, Ethanol, and Acetic Acid (Lactate, Acetate), leading to low yield.
• High Separation Cost: The presence of numerous acidic byproducts makes the separation and purification of the target Pyruvic Acid complex and expensive.
• Rate-Limiting Precursor Supply: The rate of glycolytic flux towards Pyruvate is often a bottleneck, particularly under high-concentration production conditions.

A cost-effective solution must efficiently channel carbon flux to Pyruvate while simultaneously managing product toxicity.

Solutions

We implement sophisticated Genetic and Metabolic Engineering to achieve high-titer Pyruvic Acid production:

Knockout of Competing Pathways

     

Genetically eliminate all major Pyruvate-consuming pathways (e.g., PFL, LDH) to prevent conversion into byproducts like Acetate and Lactate.

Enhanced Precursor Supply

Overexpress key enzymes like Pyruvate Carboxylase (PPC) and fine-tune glycolytic enzymes to maximize carbon flux towards the Pyruvate node.

Product Secretion Engineering

Overexpress specific membrane transporters to ensure rapid and efficient efflux (secretion) of Pyruvate from the cell, minimizing intracellular toxicity.

Toxicity Tolerance and Detoxification

Engineer hosts for enhanced tolerance to the acidic conditions and product stress, maintaining cell viability at high titers.

Our systematic strategy ensures robust carbon efficiency toward Pyruvate and enables high fermentation concentrations.

Advantages

Our Pyruvic Acid Engineering service offers the following competitive advantages:

Maximized Product Yield

Elimination of competing pathways ensures maximal carbon conversion efficiency from the sugar substrate to Pyruvate.

High Fermentation Titer

Enhanced secretion mechanisms minimize intracellular toxicity, allowing the strain to achieve significantly higher final Pyruvate concentrations.

Simplified Purification

Dramatic reduction in byproducts (Lactate, Acetate, Ethanol) simplifies the downstream separation and purification of Pyruvic Acid.

Robust Acid Tolerance

Engineered hosts maintain viability and productivity even at the low pH and high acidity characteristic of high-titer fermentation.

Efficient Glucose Utilization

Glycolytic pathway optimization ensures rapid and complete utilization of the sugar substrate for high productivity rates.

We provide a specialized platform for the sustainable and high-titer bioproduction of Pyruvic Acid.
