Microorganisms synthesize a wide spectrum of exopolysaccharides many of which have important applications in biotechnology and the food imdustry. Exopolysaccharides produced by microorganisms include:

acetan (Acetobacter xylinum)

alginate (Azotobacter vinelandii)

cellulose (Acetobacter xylinum)

chitosan (Mucorales spp.)

curdlan (Alcaligenes faecalis var. myxogenes)

cyclosophorans (Agrobacterium spp., Rhizobium spp. and Xanthomonas spp.)

dextran (Leuconostoc mesenteroides, Leuconostoc dextranicum and Lactobacillus hilgardii)

emulsan (Acinetobacter calcoaceticus)

galactoglucopolysaccharides (Achromobacter spp., Agrobacterium radiobacter, Pseudomonas marginalis, Rhizobium spp. and Zooglea spp.)

gellan (Aureomonas elodea and Sphingomonas paucimobilis)

glucuronan (Rhizobium meliloti)

N-acetyl-heparosan (Escherichia coli)

hyaluronic acid (Streptococcus equi)

indican (Beijerinckia indica)

kefiran (Lactobacillus hilgardii)

lentinan (Lentinus elodes)

Levan polysaccharide|levan (Alcaligenes viscosus, Zymomonas mobilis)

pullulan (Aureobasidium pullulans)

scleroglucan (Sclerotium rolfsii, Sclerotium delfinii and Sclerotium glucanicum)

schizophyllan (Schizophylum commune)

succinoglycan (Alcaligenes faecalis var myxogenes)

xanthan (Xanthomonas campestris)

welan (Alcaligenes spp.)
