Answer 1

14) Pseudomonas aeruginosa is a encapsulated motile rods which can withstand the antibacterial properties of soap in addition to this they are low nutrient requirement organisms which makes enable to grow on soap dish.

15) Glutaraldehyde is hazardous chemical that is used as cold sterilant to disinfect and heat sterilize heat sensitize medial, surgical and dental equipment. It is also responsible for occupational asthma and it should be handle with care or it can effects patients, doctors and environment.

16) Hydrogen peroxide has potent cleaning power with powerful disinfection and also suits the ecological environment. Hydrogen peroxide I power full disinfectant against anaerobic and aerobic organism as these e organism cannot synthesize catalase that breaks hydrogen peroxide and the hydrogen peroxide oxidizes the membrane of organisms causing the breakage of membrane thus killing microorganisms.

17) The items to be sterilized by ethylene oxide are placed in chamber and allowed with ethylene oxide gas for nearly 10-12 hours untilled the products are fully sterilized in vacuum chamber. Under this condition ethylene oxide gets penetrated into the membranes of organisms and killing them. It can be used as alternative for dry heat and moist heat sterilization.
