Isomaltose is a critical disaccharide consisting of two glucose units linked by an α-1,6-glycosidic bond. Unlike its more common isomer, maltose, isomaltose possesses unique physicochemical properties and physiological benefits, most notably its resistance to rapid digestion and its role as a core component of isomalto-oligosaccharides. At CD BioGlyco, we leverage our world-class expertise in synthetic glycobiology to provide a high-efficiency isomaltose production service. Our platform integrates advanced chassis development and enzymatic engineering to overcome the traditional bottlenecks of low yield and complex purification. By utilizing proprietary microbial chassis and optimized transglucosylation pathways, we deliver high-purity isomaltose tailored for the pharmaceutical and cosmetic industries. Whether you require a custom metabolic engineering solution or large-scale biocatalysis, CD BioGlyco is your partner in navigating the complexities of glycan synthesis.
Key Technologies
Enzymatic Transglucosylation Engineering
We utilize specialized transglucosidases (TGs) and dextransucrases that exhibit high regioselectivity for α-1,6 linkages. Through directed evolution and rational design, we enhance the thermal stability and substrate affinity of these enzymes.
Precision Chassis Development
Our team engineers robust microbial hosts, including Saccharomyces cerevisiae and Bacillus subtilis, optimized for the secretion of heterologous enzymes or the direct fermentation of isomaltose from renewable feedstocks.
Simultaneous Saccharification and Transglucosylation (SST)
This process integrates the breakdown of liquefied starch with immediate conversion to isomaltose, minimizing feedback inhibition and shortening production cycles.
Pioneering Sustainable Isomaltose Production through Advanced Biomanufacturing
The demand for functional sweeteners with low glycemic indices has surged, placing isomaltose at the forefront of nutritional innovation. CD BioGlyco provides a suite of services dedicated to the efficient production of isomaltose. Our service scope encompasses the entire development lifecycle, from initial gene discovery to finalized pilot-scale production.
We specialize in two primary development routes. The first involves direct enzymatic synthesis, where we provide high-activity enzymes or immobilized enzyme reactors to convert maltose or starch derivatives into isomaltose. This method is ideal for clients seeking rapid implementation with high purity. We optimize reaction parameters, such as pH, temperature, and substrate concentration, to maximize the transglucosylation-to-hydrolysis ratio, ensuring that the α-1,6 bond formation is favored.
The second route is our microbial cell factory development. This service focuses on constructing a synthetic biology chassis capable of producing isomaltose directly from simple sugars or agricultural by-products. We utilize genome-editing tools to eliminate competing pathways and enhance the metabolic flux toward the target disaccharide. This includes the engineering of transporters to facilitate the export of isomaltose, thereby reducing intracellular osmotic stress and increasing overall yield.
Furthermore, CD BioGlyco offers sophisticated purification and analytical verification. Using high-performance liquid chromatography (HPLC) and nuclear magnetic resonance (NMR) spectroscopy, we guarantee the structural integrity and purity of the isomaltose produced. Our services are designed to be modular, allowing clients to engage with us at any stage of their research or production pipeline.
Workflow
Project Consultation and Design
We begin with a deep dive into your specific requirements, defining the target purity, volume, and intended application. Our specialists draft a detailed technical proposal, selecting the most appropriate enzymatic or microbial strategy.
Catalyst Discovery and Engineering
If the project requires enzymatic synthesis, we screen our extensive library for transglucosidases. For custom requirements, we perform protein engineering to optimize the enzyme's performance under industrial conditions.
Chassis Construction and Optimization
For fermentation-based projects, we develop a custom microbial chassis. This involves the integration of target genes and the fine-tuning of metabolic pathways to ensure stable and high-yield production of isomaltose.
Process Optimization and Scalability
We conduct small-scale trials to optimize variables such as feeding strategies and aeration. Once a robust process is established, we perform scale-up studies in our state-of-the-art bioreactors to ensure commercial viability.
Product Recovery and Purification
Using advanced separation technologies, including ion-exchange chromatography and membrane filtration, we isolate the isomaltose from the reaction broth, achieving industry-leading purity levels.
Quality Assurance and Delivery
Every batch undergoes rigorous quality control (QC) testing, including HPLC analysis for purity and microbial limit testing. A report and the final product are then delivered to the client.

Results: This study used Bacillus subtilis AP‑1 to produce long‑chain isomaltooligosaccharides directly from maltose via fermentation. At 36 h, 50 g/L maltose yielded 36.33 g/L pure isomaltooligosaccharides (DP 2-14) with 72.7% conversion, free of glucose and maltose contamination. Structural analysis confirmed these isomaltooligosaccharides contained only α‑1,6‑glycosidic linkages. In vitro tests showed they resisted simulated oral, gastric, and intestinal digestion, selectively promoted the growth of probiotics (Bifidobacterium longum, Lactobacillus plantarum), and boosted short‑chain fatty acid production, while not supporting pathogenic bacteria (Escherichia coli, Salmonella enterica). Cytotoxicity assays verified non‑toxicity to mammalian cells up to 5 mg/mL. This simple, cost‑effective whole‑cell biocatalysis method generates high‑purity long‑chain isomaltooligosaccharides with strong prebiotic potential for functional food applications.

Applications
Pharmaceutical Formulations
Due to its stability and non-reducing nature under specific conditions, it is used as a cryoprotectant for proteins and a specialized excipient in controlled-release drug delivery systems.
Nutraceuticals
As a primary component of isomalto-oligosaccharides, it is incorporated into dietary supplements aimed at improving digestive health and enhancing mineral absorption in the intestinal tract.
Cosmetic Science
Its humectant properties make it an excellent ingredient for skincare products, helping to maintain skin hydration and improve the stability of bioactive molecules in topical creams.
Animal Nutrition and Feed
Used as a high-efficiency prebiotic additive in functional animal feed, isomaltose modulates the intestinal microbiota of livestock and pets, enhancing immune response and improving overall nutrient absorption rates.
Advantages
