MICR221 MIDTERM TEST QUESTIONS WITH ALL ANSWERS VERIFIED Extracellular Polysaccharide - Answer-Capsule! - not every bacteria -often lost in lab - ex. slime found in lungs of CF patients (pseudomonas aerginosa) is due to capsule - this is why antibiotics don't really work - can't get through capsule - protects from desiccation (98% water) - protects from predation - helps cell adhere to surfaces - but bio fouling is bad! Capsule gene organization - Answer-Region 1 - (5 genes) - tran...
