Inoculation is the start of the process. Initially the bacterial population at the time of experiment was 10,000. The number of bacterias in the lag phase increases by the following formula, . Here,  is the initial number of bacterias and  is the number of bacterias in Lag Phase. Also, the number of bacteria in the stationary phase remains the same. In the exponential phase, the bacterias grow according to the following formula,   Here,  is the time for which the exponential phase lasts. Similarly, the death/decline phase follows the following formula, Here,  is the number of bacterias in the stationary phase and  is the time for which death/decline phase lasts.  The table below represents the time period for which a certain phase lasted.  Time (in hours) Phase0 - 1.5 Lag Phase1.5 - 3.5 Exponential Phase3.5 - 12 Stationary PhaseAfter 12 hours Decline/Death Phase Q 4.1A 4Write down in the blanks proper values so that they satisfy the statements. [Do not put any commas or full stops in the values] The number of bacterias from (0 - 1.5) hours of the experiment is .The number of bacterias at the end of 3.5 hours are .The number of bacterias in the stationary phase are .The number of bacterias after 20 hours of the start of the experiment after rounding off are

5 x 104 cells of Bacillus cereus were inoculated into fresh sterile nutrient medium and incubated at 30oC. After 2 hour lag phase, cells grew exponentially with a generation time of 30 minutes. How many cells would be present after 8 hours incubation? The growth of the bacterium in log phase can be expressed by the following equations: N1 = N0 2n & g = (T1 – T0) / n Where n = number of generations, N0 = initial number of cells at a particular time (T0), N1 = final number of cells at a particular time (T1), and g = generation time Group of answer choices 1.28 x 107 cells/ml 4.10 x 107 cells/ml 2.05 x 108 cells/ml 3.28 x 109 cells/ml 5.24 x 1010 cells/ml

A bacterial strain is growing exponentially. At 10:00 am the titre of the culture is 4 x 106 cells per ml. At 4 pm, the culture is still growing exponentially and the titre has increased to 6 x 108 cells per ml. Assuming that the bacterial strain was in exponential phase growth prior to the measurements at 10:00 am, how many generations would have elapsed between 08:00 am and 4pm? Show all of your calculations. This culture will eventually reach the death phase when the nutrients become limited. What does happen in this phase? What strategies do bacteria develop to cope with nutrient shortages?
