- What is the differece between disinfection and sterilization? What is the dfference between bacterial-cidal and -static antimicrobial agents?What is the EFFECT and RATIONAL of Molten agar mixed with bacterial suspension has temperature higher than 45 oC.A microbiologist has isolated a new strain of bacteria, and is trying to characterize aspects of its growth. Three flasks of the same media have different amounts of NaCl added. Other growth conditions are identical, and the flasks inoculated at the same time. At regular intervals over a 3 hour period, culture samples are taken and turbidity is measured. Here are the absorbance values over time in a table and graphed.

What possible error could happen if a glass slide is reused for slide preparation?
- Why should agar media be completely dissolved before they are dispensed in tubes and plates? What are the bases for pegging the temperature at 1210C for 15-30 minutes during moist heat sterilization and 1800C for two (2) hours using dry heat sterilization? Can you sterilize culture media using dry heat sterilization? Why is that so? You will notice in the videos shown, the cotton plug is not used. What is role of cotton plug in media prep, sterilization and culture of microorganisms? Instead of using cotton plug, plastic screw-cap is used, can you substitute this for the former? Is it technically acceptable in microbiology?Background: The following results were obtained from a broth dilution test for microbial susceptibility. What is the minimum bactericidal concentration of this antibiotic and explain what you based your answer on?What is the amount (mL) of pre-culture (108 cell/mL) necessary to inoculate (to add) in a 2-liter culture media for a concentratio 6.5 x 106 cells/mL?
