2. You work in the restaurant industry. A small child has just vomited on a table and the surrounding floor. The areaneeds to be cleaned quickly because, well, its vomit and customers are waiting to be seated. You have a choicebetween two antimicrobials: Substance X and Substance Y. A bacterial growth chart is shown below in thepresence of the two different antimicrobials The results are below.105104103Substance XSubstance Y10210110024810Time (min)e2015 Pearsan Edrien sa) Calculate the approximate decimal reduction time (D-value) for each of the two antimicrobials tested. TheD-value is the time it takes to kill 90% of the microbes in a sample. (Hint: What is the percent differencebetween 10 and 102?)b) You need a disinfectant that works within 30 seconds. Can either of these be used?Number of living microbes

Antimicrobials are agents that either kill microorganisms (microbicidal) or stop their growth (biostatic). Antimicrobials that are used to act primarily against bacteria are called antibiotics and the ones that act against fungi are known as antifungals.D-value/decimal decay time/decimal reduction time is the time required to reduce a population of microbes by one log or by a factor of 10 at a specific temperature and under specified conditions. In other words, 10% of the organisms are reduced after one D. a. To calculate the D value: - As we can see, the time for one log cycle reduction taken by substance Y is approximately 1 minute while in the case of substance X it is approximately 2 minutes. b. None of the chemicals can be used as none of them works within 30 seconds.
