Which of the following microorganism is used for commercial production of dextran?
Select an option to attempt
Correct Answer: Option C
Explanation
Cellulose is the most abundant organic polymer on Earth and the main structural component of plant cell walls. It is a linear, unbranched homopolysaccharide of-D-glucose units linked by-1,4-glycosidic bonds (configuration at C1 of glucose). The-1,4 linkages force each successive glucose to flip 180°, creating flat, extended chains that hydrogen-bond to adjacent chains, forming highly crystalline, rigid microfibrils. Contrast with starch:-1,4 linkages (amylose) or-1,4 and-1,6 (amylopectin) create helical chains. Chitin is-1,4-linked N-acetylglucosamine. Callose is-1,3-linked glucose.
