- A bacterial organism is catalase positive and cytochrome oxidase positive. This could suggest that the organism is an obligate aerobe. True or false?What is one difference between fermentation and anaerobic respiration? Since neither requires oxygen, why would a microbe select one of these versus the other? Name a specific microbe which uses fermentation and a specific microbe which uses anaerobic respiration.A microbe that does not require oxygen for metabolism but will use it ifavailable is a/ana. microaerophile.b. facultative anaerobe.c. obligate anaerobe.d. aerotolerant anaerobe.e. obligate aerobe.
- if a bacterium lacks cytochrome C oxidase, does that make the bacterium an anaerobe? Explain?You set up an anaerobic jar and after incubation the indicator strip is blue. What can you conclude from this? Are the organisms growing on your plate anaerobes? Explain.Why do you need to use antifoams in fermentation medium? How you could avoid from contamination during fermentation?
- Would an obligate anaerobe or an obligate aerobe be more likely to produce catalase? Why?Basically, catalase tests is performed to confirm if an organism is an: A) Carbon dioxide producer B) H₂Oterminal electron acceptor C) Hydrogen peroxide detoxifier D) Oxygen producer E) FermentativeGiven what is known about humans, why is it unlikely that a thermophile or a psychrophile would be a human pathogen?
- The generation time of microbacterium cells present in activated sludge is 30 minutes. If these bacteria are allowed to grow for 15 hours, how many generation would have taken placeRequires oxygen at a lower concentration than typically found in air. Question 3 options: a) Obligate aerobe b) Facultative anaerobe c) microaerophile d) None of the aboveYou have 2 organisms, A and B. One is an obligate aerobe and the other is an obligate anaerobe. You have 2 Nutrient Agar Plate Media that these organisms can grow on. How can you differentiate which organism is aerobic and which is anaerobic?
