Which B. megaterium culture, a culture in the exponential growth phase or a culture in the stationary phase, would show the best survival following exposure to UV radiation? Explain.

Create a graph of this spectrophotometric data (using Excel or the graph paper below), labeling the four stages of the growth curve- lag, log (exponential), stationary, death. Be sure to label your axes properly and give your graph a title Time Culture Sampled                        % Absorbance 0 min                                                       5% 30min                                                              7% 60min                                                              9% 90min                                                              15% 120min                                                            25% 150min                                                            37% 180min                                                            49% 210min                                                            50% 240min                                                            49% 270min…

Is  Bacillus cereus negative or positive for growing in high salt concentrations?

Taking microbial cells out of a stationary phase culture and putting them into a fresh, sterile medium (in which they can grow) will result in the cells entering which stage of the growth cycle? Death phase O Log phase Lag phase Stationary phase
