Colanic acid is an exopolysaccharide produced by Escherichia coli. It is utilised in the food, cosmetics, pharmaceuticals, and emerging biotechnological fields due to its rheological, moisturising, and bioactive properties. In the food industry, it acts as a stabiliser and thickener to enhance texture and viscosity in products while maintaining thermal stability up to 102 degree Celsius, which makes it suitable for processed foods.
Its high-water retention from hydrophilic groups and L-fucose content is used in the cosmetics industry for moisturising, skin-whitening, and anti-inflammatory formulations. Its low-molecular-weight versions are utilised in the pharmaceutical sector for lifespan extension via mitochondrial regulation, drug delivery systems, and biomaterials, with engineered strains achieving titres up to 24.99 g/L to support scalability. Additionally, its hydrolysis yields fucose for producing human milk oligosaccharides like 2'-fucosyllactose in nutraceuticals, and surfactant-like traits suggest potential in wetting agents or biofilm therapies.
The market demand for colanic acid is driven by the rising demand in cosmetics for its moisturising and anti-ageing properties, along with expanding applications in food as a natural stabiliser and in pharmaceuticals for drug delivery and nutraceuticals derived from its fucose content. Additionally, advances in microbial engineering enable cost-effective overproduction, with titres exceeding 20 g/L, reducing production expenses and supporting scalability for industrial use. Moreover, consumer trends toward clean-label, bio-based ingredients, coupled with regulatory pushes for sustainable alternatives to synthetic polymers, further propel growth, mainly in skincare and functional foods, where its thermal stability and biocompatibility are required.
Emerging biotech needs for human milk oligosaccharides via colanic acid hydrolysis also drive R&D investment. Industrial colanic acid procurement is heavily influenced by production yield and cost factors tied to fermentation conditions such as temperature (optimal around 20-30 degree Celsius), pH, and nutrient availability, mainly glucose as a carbon source and proline as nitrogen.
Raw Material for Colanic Acid Production
According to the Colanic acid production plant project report, the various raw materials for Colanic acid production include Escherichia coli strains.
Production Process of Colanic Acid
The extensive Colanic acid production cost report consists of the following major industrial production process:
- Production via microbial fermentation: The production process of colanic acid involves microbial fermentation of engineered Escherichia coli strains, such as MG1655 derivatives with lon and hns deletions plus rcsA overexpression. It activates the RCS phosphorylation system in optimised media like TBG (TB + 20 g/L glucose) or M9 supplemented with glucose, at 25-30 degree Celsius for 22-48 hours in shake flasks or bioreactors under controlled pH and aeration. The process optimisations include boosting nucleotide sugar precursors (UDP-galactose, GDP-fucose) via overexpression of galU, gmd, manB, manC, and gale, along with CRISPRi downregulation of wcaD to lower viscosity, with glucose availability and lipopolysaccharide structure critically influencing output. Finally, downstream processing involves centrifugation to harvest supernatant, ethanol or methanol-chloroform precipitation, dialysis for purification, and lyophilisation to yield high-molecular-weight (>10 MDa) polysaccharide. The process is optionally followed by acid hydrolysis (e.g., 4% H3PO4 at 110 degree Celsius) for low-molecular-weight variants suitable for cosmetics or pharmaceuticals.
Properties of Colanic Acid
Colanic acid is a high-molecular-weight anionic heteropolysaccharide (>10 million Daltons) with a repeating hexasaccharide unit comprising D-galactose, L-fucose, D-glucose, and D-glucuronic acid in a 2:2:1:1 molar ratio, further modified by pyruvate ketals and non-stoichiometric acetyl groups, providing polyanionic character and amphiphilic properties. It appears as an amorphous white fibrous solid (density 1.35-1.45 g/cm³), exhibits hygroscopicity (15-20% moisture at 60% RH), and forms highly viscous, non-Newtonian solutions (>1% w/v) with sphere-like chain conformation, triple-helical structure.
It shows thermal stability up to 102-200 degree Celsius (melting point ~254 degree Celsius), along with excellent water retention from hydrophilic hydroxyl and carboxylate groups. It shows pH stability (3-9), pKa ~3.2-3.5 for glucuronic acid carboxyls, cation exchange capacity (2-2.5 meq/g), and spectroscopic features including IR bands at 3400 cm-1 (O-H), 1610/1415 cm-1 (COO-), and 1070 cm-1 (C-O-C), with no UV absorption >220 nm and moderate reducing ability.
