  1. I did biochemical tests on several bacterial isolates and had different results. but after identifying the type of bacteria, the bacteria is Pseudomonas aeruginosa. Why do these bacteria have different biochemical tests even though they are one type of bacteria?

    • Ya, there are some sources that say that they are encapsulated. So, we can say they are both capsulated and non-capsulated. They secrete a capsule-like polysaccharide called alginate according to Sumita Jain and Dennis E. Ohman 2005)
