Xanthan Gum Engineering Service

Xanthan Gum is a high-demand polysaccharide widely used as a Thickeners/EOR Enhanced Oil Recovery agent in food, pharmaceuticals, and industrial applications due to its exceptional viscosity and stability. The traditional fermentation process faces key difficulties: High viscosity limits oxygen transfer and increases mixing energy required in the bioreactor, and the native inconsistent quality of Xanthomonas campestris fermentation leads to variable product performance.

CD Biosynsis offers a two-pronged solution focusing on both strain performance and process engineering: Genetic Modification: Modify the Gum gene cluster to control the structure of the pentasaccharide repeating unit, tailoring the viscosity profile. This allows for customized viscosity properties. Simultaneously, we implement Bioreactor Optimization: Implement non-conventional bioreactors e.g., bubble column optimized for high-viscosity broth. This overcomes the critical mass and oxygen transfer limitations posed by the high-viscosity fermentation environment, ensuring high yield and reduced operational cost.

Pain Points

The industrial production of Xanthan Gum faces these primary challenges:

• Oxygen Transfer Limitation: The rapid increase in broth viscosity during fermentation dramatically reduces the oxygen transfer rate OTR, which is critical for the aerobic host Xanthomonas campestris, severely limiting product titer.
• High Energy Cost: Maintaining sufficient mixing and oxygen dispersion in the non-Newtonian, high-viscosity broth requires extremely high mechanical agitation energy, which is a major operational cost.
• Inconsistent Quality: Spontaneous mutations or environmental variations can lead to inconsistent molecular weight and degree of acetylation of the pentasaccharide unit, resulting in variable viscosity and functional performance.
• Strain Robustness: The native Xanthomonas campestris strain is often sensitive to shear stress and susceptible to phage contamination, impacting process reliability.

An effective solution must simultaneously address the biological limitations of the strain and the mass transfer constraints of the bioreactor.

Solutions

CD Biosynsis utilizes integrated strain and process engineering to optimize Xanthan Gum production:

Tailored Viscosity Profile

           

We genetically modify the Gum gene cluster that controls Xanthan Gum synthesis, allowing for precise control over the pentasaccharide structure and thus the final viscosity and rheological properties.

Bioreactor Mass Transfer Optimization

We implement and optimize non-conventional bioreactors e.g. airlift or bubble column, which offer high oxygen transfer and low shear stress suitable for Xanthan Gum's high-viscosity broth.

Stress and OTR Tolerance

We engineer the Xanthomonas campestris host for enhanced stress tolerance e.g. shear stress and improved intrinsic oxygen uptake rate, boosting performance under challenging fermentation conditions.

Process

Our Xanthan Gum engineering service follows a rigorous, multi-stage research workflow:

• Gum Cluster Modification: Introduce targeted gene deletions or site-directed mutagenesis in the Gum gene cluster to alter the pentasaccharide structure and control acetylation levels for viscosity tuning.
• Host Robustness Engineering: Engineer the Xanthomonas campestris strain to enhance its tolerance to shear stress and osmotic pressure, and improve its intrinsic oxygen uptake rate.
• Bioreactor System Design: Model and select the optimal non-conventional bioreactor design e.g. airlift/bubble column, and optimize aeration strategies to maximize oxygen transfer in the high-viscosity regime.
• Fermentation Process Development: Develop high-titer, fed-batch fermentation protocols specifically tailored for the engineered strain and the optimized bioreactor to achieve maximum Xanthan Gum productivity.
• Product Rheological Characterization: Measure and validate the final Xanthan Gum product's rheological properties e.g. viscosity, yield stress, shear-thinning behavior, and compare it against the target specifications.

Technical communication is maintained throughout the process, focusing on timely feedback regarding yield and product quality attributes.
