Introduction exopolysaccharides (eps) are extracellular carbohydrate polymers produced and secreted by microorganisms, which accumulate outside the cells they are capable to be released into the surrounding environment despite their monomeric composition, similar to well-known plant or animal products, the eps.
What types of information should you include in your introduction in the introduction of your thesis, you'll be trying to do three main things, which are called moves: move 1 establish your territory (say what the topic is about) move 2 establish a niche (show why there needs to be further research on your topic) move 3. Exopolysaccharide introduction bacteria synthesize anumber of polysac- charides which are defined by their location relative to the cell stimulating effect on eps syn- thesis properties isolation and purification as mentioned earlier, isolation and subse- quent purification of eps is difficult and.
