Concept explainers
To answer:
The nutritional classification of Desulforudis audaxviator. This bacterium lives underground, its energy source is sulfate, obtains electrons from hydrogen and builds the organic molecules by using the inorganic molecules seen in the nearby rocks.
Introduction:
All the bacteria require carbon source and energy source for their growth and development. Depending on the carbon and energy requirement, the bacteria can be classified into four categories, namely photoheterotrophs, photoautotrophs, chemoautotrophs, and chemoheterotrophs.
The microorganisms that utilize inorganic molecules as electron donors are known as lithotrophs. The microorganisms that use organic compounds as electron donors are known as organotrophs.

- Explain this The basic nutritional requirements of microorganisms are an energy or carbon source, an available nitrogen source, inorganic elements, and for some cell types, specific growth factors.arrow_forwardComplete the table below regarding different types of fermentation. Microbe Type of fermentation it carries out Products generated through fermentation Saccharomyces cerevisiae Escherichia coli Enterobacter aerogenes Lactobacillus acidophilusarrow_forwardWhich media is used to determine if members of the Enterobacteriacae is motile: Sulfur Indole Motility (SIM) MacConkey Agar Kligler’s Iron Agar (KIA) Urea Brotharrow_forward
- Identify the mode of nutrition (specific level) for the organisms. Spider plant I. Реаce lily Grizzly bear Ticks Thermoacidophiles Shitake mushroom Dumb cane Algae Vulture Halophiles Е. coli Pigs Ascaris Antelope Slime moldsarrow_forwardIn the Mannitol Salt Agar, why is there no observed growth of Escherichia coli?arrow_forwardAll of the following are ways microorganisms adapt to limited nutrients except: synthesize increased amount of enzymes for uptake and metabolism of limited nutrients form metabolically active highly resistant endospores synthesize enzymes needed to use a different nutrient acetic acid adjust the rate at which they metabolize nutrientsarrow_forward
- Identify physical and chemical methods used for foodpreservation. How does each method limit growth ofmicroorganisms?arrow_forwardStaphylococcus aureus is non-motile, a facultative anaerobe, and a mesophile. At 37⁰C in abundant glucose, which incubation environment is more likely to produce the highest cell mass of S. aureus within two hours? Flask with aeration to add oxygen to the broth and shaking Flask left on the lab bench Flask grown in an anaerobic chamber that removes oxygen from the air around the flask Flask without aeration All will be equalarrow_forwardTrue or false: Bacillus prefers to sporulate as soon as True O False possible upon sensing any nutrient limitationarrow_forward
- lists the major contents of the bacterium Escherichia coli.arrow_forwardDescribe the industrial fermentation process of Cephalosporin by including the type of fermentation porcess (batch, fed-batch or Continous) and bioreactor used. Also describe how the media was prepared.arrow_forwardGive 5 examples of microorganisms that may be grown in Nutrient Broth.arrow_forward
