Concept explainers

Microbial Growth

The development of microbial growth is influenced by various natural conditions (both physical and synthetic) like pH, temperature, saltiness, gas focus (O2, CO2, and H2), nutrients, water action, and assimilation. Knowing the distinctive physical and chemical factors that influence the development and endurance of microbial growth in the climate will assist with reinforcing endeavors outfitted towards their control. These lines lessen or diminish their harmful impacts on humankind, creatures, and the climate.

Which of the following experimental approaches is likely must complete picture of a particular cell's metabolism? a. NMR spectroscopey b. Metabolic inhibitors c. Mass spectroscopy d. Isotopic tracers
What statement correctly explains why moist-heat is more effective than dry-heat for sterilization purposes? The microbe's molecules are resistant to alteration in the absence of water. Dry heat will always be a lower temperature than moist heat. Dry heat dehydrates the microbes, and dehydration is a method of preserving microbes. Water is a good conductor of heat.
Which ONE of the following best describes the abbreviation ‘MIC’? Select one: A. The lowest concentration at which no microbial growth is detected B. The lowest concentration that indicates whether an antibiotic would be effective or not C. The lowest concentration which is not toxic to the host D. The lowest concentration which is least effective against the organism E. The lowest concentration which kills the organism
Microbes are exposed to a wide variety of environmental factors that affect growth and survival. By giving two (2) examples, discuss how the microbial survival in various environmental conditions has been used to understand its ability to make flavorful and long shelf-life type of foods.
There are various environmental factors that can influence microbial growth and reactions. These factors play a role which will determine if a microbe can function in a given environment. What are 2 environmental factors believed to be the most important out of the others ?
Which of the following groups of microbes is most likely to be associated with humans? A psychrophiles. B thermophiles C hyperthermophiles D mesophiles.
A drug failed to work. Even if resistance is not an issue, the antimicrobials are found to only have a discrete range of bacteria that they can exert their effects on. Why is this the found case? Question options: Microbial components vary over different species and strains. If the organism naturally doesn't express the target component, the drug won't be able to exert an effect on it. Antimicrobials are designed to be effective for a predetermined period of time. An older antibiotic can't exert any effects on a new microbial strain. There is a different antimicrobial designed for every strain of bacteria. As a result there is no crossover in action due to selective targeting. The body filters antimicrobial compounds to interact with their target microorganism. Until research determines how to control this, antimicrobials will only ever have a very discrete range of targets.
Consider that a certain antimicrobial drug prevents bacterial growth. However, when the drug treatment is stopped, the bacteria resumes growth. This antimicrobial drug would be considered narrow-spectrum. bacteriostatic. toxic. broad-spectrum. bacteriocidal.
Besides dehydrated foods, how might the amount of water available to microbes be decreased? Group of answer choices Treatment by non-ionizing radiation. Treatment at high pressures for extended periods of time. Storage at temperatures between -2 and 4 °C. Pasteurization Addition of solutes such as salt or sugar.
Design a concept map on microbial growth that would contain the key features of the following concepts (Requirements of microbial growth, Bacterial Growth, Control of Bacterial Growth and Antimicrobial methods).
Explain the difference in Microbial Inhibitory Concentration and Microbial Bactericidal Concentration. (When explaining differences you have to talk about both things being compared. Just explain how they are different. Definitions will not be accepted.)
Which of following statements is TRUE about antiseptics and disinfectants? A. Disc diffusion works because the disc is soaked in bacteria and is the exposed to antimicrobial. B. You can tell the characteristics of the zone inhibition whether an organism is cidal or static in its effect. C.The shape of an object being cleaned may influence the effectiveness of germicides D. Gram + organisms are more resistant than Gram - organisms E. A large zone of inhibition shows bactericidal effect
