Erythritol, a four-carbon sugar alcohol (polyol), has emerged as the gold standard in the global sweetener market due to its nearly zero-calorie profile, high digestive tolerance, and non-glycemic properties. Unlike artificial sweeteners, erythritol provides a clean, sucrose-like taste without the bitter aftertaste, making it indispensable for the food, beverage, and pharmaceutical sectors. As a pioneer in synthetic glycobiology, CD BioGlyco offers an erythritol production service that bridges the gap between laboratory-scale metabolic engineering and industrial-grade manufacturing. Our platform leverages advanced chassis development and synthetic biology tools to optimize the biosynthetic pathways of osmophilic yeasts and specialized microorganisms. By utilizing high-efficiency strains like Yarrowia lipolytica and Moniliella pollinis, we help clients overcome traditional production bottlenecks, such as low yield, high substrate costs, and complex purification requirements. Whether you are looking to develop a novel microbial chassis or optimize an existing fermentation process, CD BioGlyco provides the technical expertise and infrastructure to accelerate your project from concept to commercialization.
Key Technologies
Advanced Metabolic Pathway Engineering
We utilize gene editing tools to rewire the central carbon metabolism of host strains. Our focus is on enhancing the pentose phosphate pathway (PPP), which is the primary route for erythritol synthesis. By overexpressing key enzymes such as glucose-6-phosphate dehydrogenase (G6PD) and erythrose-4-phosphate phosphatase, and downregulating competing pathways (e.g., ethanol or glycogen synthesis), we increase the erythritol titer and yield.
High-Throughput Synthetic Microbial Biosensor (SMB) System
To accelerate the screening of hyper-producing mutants, we implement SMB systems that link erythritol concentration to a measurable signal, such as fluorescence. This technology allows for the rapid evaluation of thousands of genetic variants in real-time, ensuring that only the most robust and productive strains proceed to fermentation optimization, drastically reducing development timelines.
Precision Fermentation and Process Control
Our platform integrates real-time monitoring of dissolved oxygen (DO), pH, and osmotic stress. Erythritol production is often a response to osmotic pressure; therefore, we utilize sophisticated fed-batch strategies and osmotic-stress-responsive genetic targets to maintain optimal cellular health while driving maximum product accumulation in the medium.
Empowering Next-Generation Sweetener Production Through Precision Glyco-Engineering
At CD BioGlyco, our service scope is designed to support the entire lifecycle of erythritol development. We recognize that the economic viability of erythritol depends heavily on the "triple crown" of fermentation: high titer, high yield, and high productivity. Our services are categorized under chassis development and sweetener production service, providing a modular yet integrated approach to satisfy diverse client needs.
Microbial Chassis Development
We specialize in the engineering of robust microbial hosts tailored for polyol synthesis. While many providers rely on wild-type strains, CD BioGlyco develops custom chassis that are optimized for specific industrial conditions. This includes the development of thermotolerant strains capable of maintaining high productivity at elevated temperatures, which reduces cooling costs during large-scale fermentation. We also engineer strains with enhanced tolerance to crude substrates, such as glycerol or molasses, enabling the use of low-cost feedstocks without compromising purity.
Fermentation Optimization and Scaling
Our team provides detailed implementation of fermentation strategies, including batch, fed-batch, and continuous fermentation models. We handle the optimization of the carbon-to-nitrogen (C/N) ratio and the fine-tuning of mineral supplementation to ensure the metabolic pathway is energetically favorable for erythritol conversion.
Downstream Processing (DSP) and Purification
The final stage of our service involves the development of efficient recovery methods. We utilize advanced chromatographic separation, ion exchange, and vacuum crystallization techniques to achieve erythritol crystals with a purity of >95%. Our processes are designed to eliminate common by-products like glycerol and ribitol, ensuring the final product meets the standards of the pharmaceutical industry.
Workflow
Project Consultation and Design
The process begins with a deep dive into the client's specific requirements, including target yield, preferred substrates, and final application. Our experts design a customized genetic and process roadmap to ensure all technical and economic goals are met.
Strain Engineering and Genetic Modification
Using our platform, we perform precise genomic alterations. This includes the insertion of high-activity erythrose reductases (ER) and the deletion of genes responsible for erythritol catabolism (e.g., EYK1), ensuring that the produced erythritol is not re-consumed by the host.
High-Throughput Screening (HTS)
Engineered libraries are screened using our SMB system or microfluidic platforms. We select the top-performing clones based on their growth kinetics and erythritol production rates under simulated industrial conditions.
Lab-Scale Fermentation Optimization
The selected strains undergo rigorous testing in benchtop bioreactors (1L to 10L). We perform one-factor-at-a-time (OFAT) and response surface methodology (RSM) experiments to identify the optimal pH, temperature, and feeding profiles.
Pilot-Scale Validation and Scaling
To ensure translatability, we validate the optimized process in larger bioreactors (100L to 1000L). This stage focuses on maintaining oxygen transfer efficiency and managing the heat generated during high-density cultivation.
Purification and Quality Control (QC)
The fermentation broth is processed through our DSP pipeline. We conduct QC using liquid chromatography-mass spectrometry (LC-MS) and nuclear magnetic resonance (NMR) to verify the structure, purity, and safety of the erythritol.

Results: This study optimized erythritol fermentation by Moniliella pollinis mutant SP5 using molasses as a low‑cost carbon source. Using the OFAT method, researchers optimized key parameters: 200 g/L molasses, 7 g/L yeast extract (C/N ratio 200:7), 25 g/L NaCl, and initial pH 5. Under batch fermentation, the maximum erythritol titer reached 17.48 ± 0.86 g/L, with a yield of 0.262 g/g and productivity of 0.095 g/Lh. Fed‑batch fermentation, feeding 25 g/L molasses on days 2 and 3, further boosted production to 26.52 ± 1.61 g/L, a 51% increase, with a yield of 0.501 g/g and productivity 0.158 g/L·h. These results demonstrate that medium optimization and fed‑batch operation enhance erythritol production, providing a feasible, cost‑effective approach for industrial bioproduction.
