53.  Which one of the following bacteria group CANNOT survive in presence of oxygen? Group of answer choices obligate aerobes obligate fermenters facultative aerobes anaerobes microaerophiles aerotolerant   54.  Identify the MISMATCH pair from the following,  Group of answer choices E.coli  :::: facultative aerobe group Bacteroides :::: obligate anaerobes none of the above is a mismatched pair Chlamydia sps :::: cell culture for cultivation Gardnerella sps :::: bacterial vaginosis Staphylococcus sps :::: can tolerate 20 % salt; cause pimples Rickettsias :::: obligate intracellular parasite

1. Plate count data are used to calculate microbial population density as colony forming units (CFUs) per milliliter of culture. Culture density (CFU/mL) = number of colonies (dilution factor) x (volume plated, in mL) Use these data below to calculate the CFU/mL in this sample of bacteria after 1 hr of growth. **Important to know for these types of questions - only use colony counts that fall between 10 and 300. TNTC = too numerous to count, so many colonies that you can't distinguish them to count. Use the plates with numbers of colonies that can be counted, calculate the CFU on each one, and then calculate the average between all of them. Looking for more assistance? Read section 7.3 in the textbook. Time 1h Dilution (before plating) Volume spread on plate 0.1 mL 0.1 mL 0.1 mL 0.1 mL none 1:10 (1 x 10-¹) 1:100 (1 x 10-²) 1:1,000 (1 x 10-³) Number of colonies observed (replicate plates) TNTC 499 83 10 TNTC 518 87 8 TNTC indicates too numerous to count. *Cell density could not be…

What are common, everyday examples that involve the following microbes: Psycrotroph, Mesophile, Thermophile

Hi can I get help on this microbiology question please? I am stuck and do not understand it. Thank you A prokaryotic cell hitched a ride to Earth on a space shuttle from some unknown planet. Microbiologists studied the microorganism and concluded it is a psychrophile, an obligate halophile, and an obligate aerobe. 1. Based on the characteristics of the microorganism described in this case, describe at least three characteristics that the unknown planet where the microorganism lived before must have so that it can survive in it. 2. Explain the following microbial characteristics or terms in complete sentences: psychrophile. obligate halophile. obligate aerobe.
