- Another method of microbial control is filtration. List down at least 5 kinds of filters which could be used for this method?Why is the membrane filter method preferred to the most probable numbermethod (MPN) for the microbiological analysis of water samples?Below is a scenario requiring the use of laboratory equipment and instruments. A watery fecal sample is tested for the presence of Bacillus cereus and Vibrio cholerae. The sample is stored in a screw capped tube. You are tasked to grow the Bacillus in a solid medium while Vibrio in a liquid medium. Choices: A. Incubator, B Hanging Drop Slide , C.Petri Dish, D. Drying Oven, E. Bunsen Burner, F. Inoculating NeedlE , G. Volumetric Pipette, H. Screw-capped Tubes, I. Hot plate, J. Centrifuge, K. Inoculating Loop, L. Microscope, M. Beaker, N. Biosafety Cabinet 1. What could be used to determine if there are more bacteria in the sample aside from Bacillus and Vibrio? 2. What should you use if you want to observe the natural motility of Bacillus under a Brightfield microscope? 3. Where should you perform the task of sterilization and inoculation? 4.What should be used to transfer the sample to the broth? 5. What could be used to separate the solid from the liquid portion of the…

METHOD:RATIONALE:What summary can be drawn from the stab slant and surface inoculation.What would be the expected out come of a Nitrate reduction test If the bacteria is a pathogenic intestinal bacteria?
- What Gram-negative bacterium might you come into contact with in a unsanitary hot tub? asap please detail explanation neededIf you did the multiple-tube technique, list one advantage and one disadvantage of each method of detecting coliforms?Using aseptic techniques, list the general procedure of inoculating a broth from a plate culture.
- Why is water tested for coliform bacteria rather than for pathogenic bacteria which may be present?Identification of an organism does not require a pure culture because Bergey’s Manual will sort out the contaminant. Identification of an organism does not require a pure culture because Bergey’s Manual will sort out the contaminant. True FalseAs a water treatment expert, please clearly highlight the potential limitation of the treatment approach that only focuses on elimination of coliforms.
