- What is the key difference between reactions that result in the final product of fermentation to form lactic acid or alcohol? What significance do these differences have in terms of microbial technology?Which of the following statements regarding low temperature storage is FALSE? Question options: freezing inhibits microbes through the unavailability of water freezing causes microbial death largely through DNA denaturation all of these statements are TRUE refrigeration functions largely by reducing the metabolic rate of microbes psychrophiles are generally not effectively inhibited by refrigeration many bacteria can survive freezing for years at a timeIn treating an oil spill, why might biostimulation be preferred over bioaugmentation?
- Which of the following statements regarding low temperature storage is FALSE? Question options: all of these statements are TRUE refigeration inhibits microbes through the unavailability of water low temperature storage the metabolic rate of microbes many bacteria can survive freezing for years at a time psychrophiles are generally not effectively inhibited by refrigeration freezing causes microbial death through membrane destructionMannitol salt agar (MSA) only allows the growth of halophiles. Among the halophiles, mannitol fermenters release acid that turns the pH indicator yellow; mannitol non-fermenters leave the medium red. Onto MSA you inoculate a halophilic mannitol non-fermenter and a non-halophilic mannitol non-fermenter. What are your expected results in this experiment? Explain the role of the media in this case.Microbial fermentation can be carried out as either a once off ----------------- culture or a-------------------------- culture. The correct terminology for these respective cultures & the vessel the latter is carried out in are? Select one: a. continuous, batch, fermenter b. batch, continuous, chemostat c. batch, continuous, turbidostat d. batch, continuous, turbidostat e. continuous, batch, chemostat
- Which of the following terms is NOT used to describe microbes thrive in different temperature ranges? Thermophiles Psychrophiles O Mesophiles O HalophilesWhy bacterium Thermus thermophilus is used ?Menaquinones is produced by Flavobacterium meningosepticum via submerged fermentation with 60% working volume in 30-L fermentation. To obtain the crude menaquinones, the fermentation medium is centrifuged at 12,000 rpm for 15 minutes. The vacuum-freeze dried particles are crushed and collected. After that the samples are treated with methanol for 20 minutes. To remove polar lipid compounds from bacterial cells, HZ816 macroporous adsorption resin column is used with methanol-dichloromethane (l:1) as mobile phase and flow rate of 0.75 mL/min. Rotary evaporation at 500 C is carried out to concentrate the eluent. After that, the concentrated sample is purified with Bio-BeadsTM S-X3 to remove components without UV absorption. To obtain the homolog purified menaquinones, RP-C18 column is used. Recrystallization is carried out to obtain pure crystalized menaquinones. Answer the following: Indicate how to obtain the sample in the methanol solvent. Three different chromatography are used in…
