- Most bacteria require a water activity of 0.9 or higher to grow. A prolonged period of being dry usually causes loss of viability. How were there still living bacteria in many of the dried foods such as dried rice, dehydrated coconut flakes, raisins, etc.? Discuss.arrow_forwardBacterial growth depends on many environmental factors, including the temperature of the environment. Since microbes can survive in a certain range of temperatures and will thrive at a temperature, understanding these variables allows for control of their growth. This understanding can be used, for example, to preserve certain foods or to treat infections. This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution. Microbial populations grow at different rates based on temperature. One way to measure growth is by turbidity measurements. When bacteria multiply in a broth culture they turn the clear solution cloudy, or turbid. a) in your own words explain the proper steps to Inoculate 5°C sterile broth tube using aseptic techniquearrow_forwardWhy is E. coli O157:H7 an organism of concern in contaminated foods?

- All bacteria produce spores. a) Trueb) Falsearrow_forward1) Listen In the lab you are testing a bacterium's oxygen requirement for growth. You grow your bacterium in a test tube, without shaking at the appropriate temperature. The next day you find that your bacterial culture is growing only at the top surface (ie at the top of the tube closest to the cap) and not dispersed throughout the test tube. What term would be used to describe the oxygen requirement of this bacterium? O A) Obligate aerobe. O B) Microaerophile. O C) Anaerobe. D) Obligate anaerobe. E) Facultative anaerobe.arrow_forwardThese structures allow bacteria to have reserve deposits of lipids or gasses. O a) inclusions Ob) ribosomes Oc) endosporesarrow_forward
